2014-2018 Silverado/Sierra 1500 60" Traction Bar Kit (RCLB/CCSB/ECSB)

Stop axle wrap for good

Wehrli builds its traction bars in-house and warrants them for life, to the original buyer, if a bar bends or breaks. Added power can twist a leaf-spring axle, which leads to broken U-joints and driveshafts and even twisted axle housings; the bars stop that wrap-up.

The axle brackets bolt under the axle tube with the axle U-bolts, and the front mounts weld to the frame. A rebuildable, greaseable RockJock Johnny Joint at the frame allows adjustment if you raise or lower the rear, and a polyurethane bushing at the axle keeps noise and vibration down. The bars are powder coated over an epoxy primer, which Wehrli says gives far better corrosion protection than a single coat.

Who it's for

Owners of 2014-2018 Chevrolet Silverado / GMC Sierra 1500 (regular cab long bed, extended cab short bed, crew cab short bed) who are adding power or towing heavy.
