Product information updated on 2021-10-07, Manufactured by BDS Suspension - Part Number BDS:128408, 2007 to 2020 Tundra Recoil Mount Kit, , These new RECOIL traction bars are built to the highest standards for the ultimate performance on and off-road. The bars are fabricated from 2" OD x 3/16'' wall steel tubing with a threaded bung welded in toward the axle and a CNC machined end at the frame. The axle mount uses the tried and true BDS large forged flex end and jam nut to take whatever abuse you throw at it. Utilizing a forged housing with large 1-1/4" -12 threaded shank, a single sided snap ring and 1-piece flex ball, the flex ends are capable of up to 15-degrees of misalignment in either direction. At the frame end the bar uses a durometer specific polyurethane bushing and free floats in the traction bar utilizing a pair of dual stage internal compression springs and UHMW polyurethane bearings. The main spring has a 3000lb spring rate. Both ends are greaseable and serviceable. Fully assembled the RECOIL traction bars are 60" long and mount to the vehicle using fabricated 1/4" steel brackets. Bracket kits are vehicle specific. The mounting brackets are designed for easy bolt-on installation. The traction bars and mounting brackets use a durable gloss black powdercoat finish. These new RECOIL traction bars are built to the highest standards featuring quick and easy adjustment while installed on the vehicle. To adjust spring tension, use the supplied spanner wrenches at the axle to loosen the jam nut. From there the main bar can be rotated to load or unload the springs at the frame side of the bar. Using the concave end of the wrench handle against the frame end check the location of the end of the main bar in relation to the notches on the wrench to verify the load on the springs, the shorter the distance the more loaded the springs are. Repeat this process on the other traction bar and use the wrenches to tighten down the jam nuts and you are ready to go! Join the revolution with the next generation RECOIL traction bars from BDS Suspension.
