The Expedition One™ Trail Series™Rear Bumper with Smooth Motion Swinging Tire Carrier system is recognized thoughout the off-road industry as one of the best new products for the JK Wrangler. Bumpers are constructed of high-grade, precision cut 3/16" steel. Standard on all bumpers are 1" thick 3/4" recovery shackle mounts. The Expedition one™ Smooth Motion STC system™ allows you to open the taligate in one smooth motion. This unique system pioneered by Expedition One integrates the carrier and rear gate with an adjustable coupling system. This makes it so the extra weight of an over-sized tire is carried by the bumper and chassis, increase the life of the rear gate and stock hinges. This makes for a long lasting and rattle free carrier system. Gen II design incorporates a modular mounting system for options to add such as hi-lift jack mount, CB mount, auxiliary rack (coming soon), and utility can mounts (also coming soon). Expedition One JK Rear Bumper comes optional with a 2 stage zinc primed textured black powder coat standard, or can be ordered bare. Rear bumper is designed to utilize the stock receiver hitch. Tire carrier system can hold up to a 40" tire. Bumper may also be ordered without the tire carrier.
