2001-2010 Duramax 60" Traction Bar Kit (RCLB/CCSB/ECSB)

Classic 2001–2010 Duramax HDs still earn their keep towing and making power — and axle wrap still breaks U-joints and yokes when the leaf pack can’t hold the pinion. Wehrli’s 60" traction bar kit adds RockJock Johnny Joints at the frame and a poly bushing at the axle so the truck stays planted without dual-heim chatter.

This kit (WCF100850): Regular Cab Long Bed, Extended Cab Short Bed, and Crew Cab Short Bed for 2001–2010 GM HD trucks. Axle mounts bolt on via the U-bolts; confirm frame-side mount path for your cab/bed.

Wrong kit?

• Extended Cab Long Bed or Crew Cab Long Bed → WCF100852 (68")
• Lift with U-bolts flipped up → WCF100854 family
• Rear block over 5" or ~6"+ total lift → often the 68" kit; measure axle-to-frame on a big lift

Colors: WCFab Red, Gloss Black, Flat Black, and Gloss White commonly ship in a few business days; other powder colors have a longer lead. Local installs available in Idaho Falls when bay time allows.
