Standard Width Jeep JK Rear Crusher Flares with Black SpyderShell

The Jeep JK's thin sheetmetal fenders and stock plastic flares are among the most vulnerable body components when traversing the trail. The Poison Spyder JK Rear Crusher Flare™ kit improves both the aesthetics and durability of your Jeep during your off road adventures. Poison Spyder Standard Width JK Crusher Flares™ provide tire coverage similar to the factory flares, with the added advantage of a better departure angle and outer tire clearance. Steel Crusher Flares™ and Poison Spyder's exclusive Inner Brace system are the ultimate in fender armor for your JK, with the toughness to withstand punishing scrapes with granite canyon walls. This product is finished in black with Poison Spyder's proprietary SpyderShell™ Armor Coat process.

Product Description

Steel JK Crusher Flares™ are constructed using 1.5" X .120" wall DOM (Drawn-Over-Mandrel) structural tubing as the outer "rub rail". This DOM tubing provides better resistance to crushing, kinking, and bending than competitors' flares made with thinner wall, welded seam tubing. The foundation of the Crusher Flare is a CNC laser cut, 3/16" thick steel mounting plate, precision brake-formed to conform to the subtle curves of the JK's body panels. Mounting holes are countersunk for the use of flat-head stainless steel mounting hardware. The top plate is CNC laser cut 1/8" aluminum plate, which is hand formed around the curves of the Crusher Flare for a factory appearance that matches the JK's organic body lines better than any other aftermarket metal flare available.

Roll-Bent Outer Tubes
Poison Spyder Crusher Flares™ were the first all-metal armored flare on the market when the Jeep JK debuted with the 2007 model year. Since then dozens of companies have tried to duplicate the original. But Poison Spyder stays a step ahead, and now Crusher Flares™ are the only metal armored flare on the market constructed with CNC ROLL-BENT OUTER TUBES. Using the latest technology in computer-controlled roll-benders to form these tubes results in several advantages. First, and most obviously, roll-bending results in a much more elegant product, whose subtle curves match the lines of the Jeep JK perfectly. Our competitors' products are easy to spot because parts made on traditional tube benders have sharp, segmented bends that simply can't match the Jeep's body lines as well. The other benefit is that roll-bending is a gentler process, resulting in less weakening of the tube where it stretches or compresses around bends. ONLY Poison Spyder Crusher Flares™ are manufactured with this state-of-the-art CNC roll-bending process!

SpyderShell™ Armor Coat
SpyderShell™ is more than just powder coating—it's a complete system that includes the state of the art in preparation, application, materials and packaging to ensure that your SpyderShell™ products stay looking great for years. The SpyderShell™ process has been engineered to provide your Poison Spyder product with years of unmatched great looks, corrosion protection and weather-resistance. Our proprietary 6-stage system starts with media blasting the entire part, to remove contaminents and prep the metal surface for the best possible adhesion. Next, any seams are sealed with 3M Scotch-Weld to block moisture from entering and causing corrosion where the powder can not reach. The first coat to be applied is a zinc-rich powdered black primer, which is baked on to form an impenetrable bond between the metal product and the coating. The primer is black--rather than traditional gray--so that any rock chips or trail damage are less conspicuous. The final top coat is an industrial grade, "super-durable" architectural finish in semi-gloss black, which is engineered to retain its appearance through years of exposure to sun and weather. SpyderShell is a coating process unmatched by any other Jeep armor aftermarket manufacturer, for which we are confident in offering a 5-year warranty on materials and workmanship.

Exclusive Inner Brace Set
Every set of Poison Spyder JK Crusher Flares™ comes with a set of inner braces that tie the Crusher Flare in to the sturdier, heavier-gauge steel of the JK's inner body tub structure. Competitors' JK Flare products simply bolt directly to the outer layer of the JK's body sheetmetal. But as any JK owner knows, the exterior sheetmetal is very thin and flexible. Simply bolting a heavy duty fender directly to the exterior sheetmetal without the inner bracing is a disaster waiting to happen. Regardless of how sturdy the flare is built, upon contact with rocks, trees, etc., it will simply push in and deform the flimsy sheetmetal it is bolted to, possibly causing expensive and unsightly damage. The Inner Brace Set that comes with Poison Spyder Crusher Flares™ effectively bypasses the outer sheetmetal, instead transferring those forces to the much stronger inner structure of the Jeep. These Inner Braces are CNC laser cut, brake-formed for a great fit and simple installation.

Provisions for LED Marker Lamps
The JK Rear Crusher Flare™ Kit comes standard with mounting provisions to place a small 3/4" LED marker lamp inside the flare just rearward of the tire. The LED can be wired in to the Jeep's running lights or turn signal circuits. 3/4" amber LED lamps are available separately from Poison Spyder.

Steel or Aluminum?
Not sure whether to choose steel or aluminum for your Crusher Flares? Aluminum is lighter in weight, so might be the best choice for those looking to save weight on their heavy JK's in order to improve fuel mileage and gain an advantage off-road. However, when wheeling with aluminum flares it is up to the driver to use more care and finesse, as the aluminum components are not going to be able to withstand the same direct impacts that steel can. The outer tube on our aluminum Crusher Flares is beefy .188" wall thickness. Compared to our steel Crusher Flares which use .120" wall DOM steel tubing. The thicker tube wall recoups some of the strength lost by going to aluminum, however the steel versions will still be stronger in a direct impact with the rocks. Aluminum JK Crusher Flares are less than half the weight of the steel version. Which is best for you will depend on your particular intended use of the Jeep, driving style and other factors.

Features & Benefits

At Poison Spyder we strive to build superior features into every aspect of each product we make. Every feature has a reason for being included in the design. Here are a list of the most important of these features, along with an explanation of the benefits of each. Consider these important factors when shopping for products, and compare the competition to Poison Spyder's features and benefits!

Feature Benefit
SpyderShell™ Armor Coat The best-looking, most durable finish coating available from any 4X4 aftermarket products manufacturer.
Best Looking Flare The Poison Spyder JK Crusher Flare™ is designed to be an aesthetically pleasing match to the curves and bends of the JK's body lines. Compare the appearance of a properly installed Crusher Flare™ to competing flares with straighter tubes, sharper bends, and an overall appearance that just looks out of place on the JK.
Inner Brace Kit Transfers impact forces through the Crusher Flare™ to the sturdy inner tube of the Jeep, which is made of much thicker material than the thin sheetmetal exterior skin. Metal JK flares that do not have inner braces just bolt directly to the flimsy exterior sheetmetal, and can dent or crease that sheetmetal if the rigid flare bumps into rocks, trees, etc.
Steel or Aluminum Construction Crusher Flares™ are available in either heavy duty steel or light weight aluminum, to suit the needs of a wide variety of Jeep owners and their four-wheeling requirements. Choose steel for heavy duty ruggedness, for use on Jeeps that see a lot of time in the rocks and hard core wheeling. Opt for aluminum when weight savings is an issue, or on Jeeps that will only see mild off-road use with reduced chances of encounters with the rocks.
3/16" Thick Mount Plate The mounting plate is CNC laser cut and precision brake-formed for a great fit to the Jeep JK's flare mounting surfaces. This thick material helps spread impact loads over a wide area, reducing potential damage. Mounting holes are countersunk so that flat head hardware may be used for a sleek, flat surface.
1.5" OD, .120" Wall DOM Tubing Steel Crusher Flares™ use a 1.5" diameter, .120" wall Drawn-Over-Mandrel (DOM) high strength structural steel tube as the outer "rub rail". Compare this to competing products on the market which use weaker welded seam tubing, which is less resistant to bending and kinking than DOM.
.188" Wall Aluminum Tubing Aluminum Crusher Flares™ employ a 1.5" diameter, .188" wall annealed aluminum tube as the outer "rub rail". This is the component of the flare that is most likely to come in contact with rocks and other obstacles. The thick wall of the aluminum tubing helps to guard against denting and bending. This tube is formed in an NC bender and securely fixtured during assembly to ensure quality.
3D-CAD Designed Assembly Fixtures Crusher Flares™ are built in assembly fixtures that were designed simultaneously with the Crusher Flares™ themselves. The process involves using 3D Computer Aided Design and an actual 3D solid model of the Jeep JK to render the subtle curves and compound surfaces of the JK. The manufacturing process using these fixtures is similar to building the part in-place, right on the Jeep, with fixtures to hold each component securely in place while welding it all together, ensuring against heat warping. The result is the best looking, best fitting, easiest to install, most consistent quality Crusher Flare™ ever produced.

Frequently Asked Questions

Got a question about this product? We've tried to cover the most frequently asked ones below. You may also want to check our Master FAQ Page for more general questions about Poison Spyder, our products, ordering and shipping. Don't see an answer to your question? Ask our sales department by email at [email protected], and we'll get back to you as soon as possible with the information you need.

Q: You offer Narrow Crusher Flares for the front, but I don't see them listed for the rear?

A: If you look at the stock plastic JK flares, you'll notice that the rear ones are quite a bit narrower than the fronts, as the nose of the JK tapers considerably toward the front. Our Standard Width Crusher Flares™ were originally designed to approximate the width of the factory plastic flares, and as a result, the Standard Width Rear Crusher Flares™ are already quite a bit narrower than the front ones. As it turns out, the Front Narrow JK Crusher Flares™ are actually a very close match with the Standard Width rears. In fact they match so well that an even narrower rear flare wouldn't look right. So we recommend running the Narrow fronts with the Standard rears.

Q: How do I choose between steel and aluminum?

A: It depends on how you use your Jeep, what kind of wheeling you do, and which product you're considering. For armor used on Jeeps that get wheeled hard in extreme rock terrain, we prefer steel because it is simply more durable, less susceptible to bending or gouging, and will distribute impact loads over wider areas better. But the trade-off is that steel is of course heavier. There are some who prefer a lighter rig even in hard core terrain, opting to use aluminum but accepting the greater risk of damage in order to gain the performance of a lighter rig. For these folks, if their driving style is more finessed and patient, aluminum might be the better choice. For vehicles being used primarily on the street, and light trail duty, the aluminum products might be the better choice solely for the weight savings.

5 of 5 Look great April 26, 2019
Reviewer: Scott Haas from Monclova, OH United States  
Installed myself.  Definitely you need a good nutsert tool.  I put cut my own foam backing for the flares. Also used red
Loctite on the Nutserts to seal the edge and help keep them from spinning.  I used a Length of 1 1/4 PCV pipe to support the fender when installing.  You have put it on and off a few times during the install and it is too heavy for one hand.

3 of 5 Disapointed February 7, 2017
Reviewer: Michael Verley from Meridian, MS United States  
Ok first I would like to say I think Poison Spyder has a great design team. But there finished product has a lot to be desired.  I had heavy weld splatter all over the inside of the Crusher Fenders front and rear. The weld splatter was everywhere even in the counter sinks and to make it worse they powder coated over the splatter. Needless to say I was very disappointed with their craftsmanship.
