Poison Spyder Rear Spreader Bar Kits are the easy way to add rear-seat protection to the stock Jeep roll bar. The kit consists of a rear spreader bar and two center stringers to tie the main hoop of the stock roll bar to the rear spreader. All components are made of 1.75″ OD, .120″ wall DOM tubing. each piece is CNC laser notched and NC-bent for a quick, hassle-free installation with no extra notching, fitting and grinding. Requires welding. The Rear Spreader Bar Kit is best used in conjunction with our Trail Cage Kit to result in a complete full cage. Note that the installed photo below depicts an LJ Unlimited. The TJ version is identical but shorter.
