2020-2026 Duramax 68" Traction Bar Kit (DCLB/CCLB)

Long-bed Duramax trucks that tow hard or make more power need the axle locked down before wrap eats U-joints and yokes. Wehrli’s 68" traction bar kit for 2020–2026 GM HD trucks uses rebuildable RockJock Johnny Joints at the frame and a poly bushing at the axle so it stays quiet on the street while holding the pinion where it belongs.

This kit (WCF100876): Double Cab Long Bed and Crew Cab Long Bed. Frame-side mounts typically need welding (Crew Cab Short Bed is the bolt-on DIY path on the companion 60" kit). Competition trucks should weld the front mounts for max strength.

Wrong kit?

• Regular Cab Long Bed, Double Cab Short Bed, or Crew Cab Short Bed → WCF100826 (60")
• Lift with U-bolts flipped up → alternate Wehrli kit (call us — usually WCF100854 family)
• Rear block over 5" or ~6"+ total lift → this 68" kit is often correct; still measure axle-to-frame mount distance on a big lift

Colors: WCFab Red, Gloss Black, and Gloss White commonly ship in a few business days; other powder colors have a longer lead. We can order the color you want and install in Idaho Falls when the bay’s open.

Call 208-542-7793 with year, cab, bed, and lift height before you buy if you’re not sure.
