The Poison Spyder Trail Cage is designed for those Jeep YJ, TJ and LJ owners who already have the factory roll bar, and would like to add on to it to form a full roll cage rather than installing a complete new cage. The Trail Cage kit is an eight piece set. It comes with two Lower A-Pillars (dash to floor supports) and two tubular Upper A-pillars that are to be welded to the factory windshield bars. Also included are a dash bar, upper windshield bar, and two center spreaders that can be located in several positions.
The Poison Spyder Trail Cage kit comes disassembled and requires welding to install. The Lower A-Pillar is designed to provide a strong foundation for the forward section of the cage while not intruding into the dash or compromising legroom. The Trail Cage is secured at the windshield, at the front gusseted A-Pillar, at factory mounts on the door jamb and to the floor through the forward drain hole. This provides solid strength from the top of the windshield to the floor. The Lower A-Pillars and gussets are CNC laser cut and precision brake-formed for quality and fit. Tubular kit components are constructed from 1.75" .120 wall DOM structural tubing. All tubular components are CNC-bent and laser-notched for a precise fit, and laser-marked with reference numbers for easy identification and installation.
The Heavy Duty Header Bar Kit is sold separately but is a highly recommended addition to the Trail Cage installation. The Trail Cage can be installed with the stock header bars, but those are little more than thin-wall tubing intended to brace the windshield, providing little in the way of cage protection. Our Heavy Duty Header Bar Kit replaces them with precision-manufactured, high strength components that work withh your stock roll bar and Poison Spyder Trail Cage Kit to provide the strength and safety of a real deal, heavy duty cage. The Heavy Duty Header Bars are made from high strength 1-3/4" X .120 wall DOM structural tubing, laser notched and expertly welded to CNC laser cut 3/16" mount plates. For comparison, the stock header bars are made of .095 wall welded seam tubing, withh thin gauge stamped metal mounting flanges. The DOM tubing used in the Poison Spyder kit has a yield strength of 70,000 psi, with a tensile strength of 44,668 lbs. Compare that to the welded seam tubing of the stock header bars, at 40,0000 psi yield strength and only 19,757 lbs. tensile strength. The Heavy Duty Header Bar Kit may also be installed by itself without the Trail Cage, or with other manufacturer's add-on cage kits.
