Wehrli 20-24 Chevy & GMC Duramax RCLB/CCSB/ECSB 60in. Traction Bar Kit - Illus Purple

This Wehrli Custom Fabrication (WCFab) 60-inch traction bar kit (WCF100826-IP) is designed for 2020-2026 GM HD Duramax trucks, specifically for Regular Cab Long Bed (RCLB), Extended Cab Short Bed (ECSB), and Crew Cab Short Bed (CCSB) models. Traction bars are a critical upgrade for diesel trucks with increased horsepower or those towing heavy loads, as they prevent axle twisting. Axle twisting can lead to damage to u-joints, pinion yokes, driveshafts, and even twisted axle housings.

The kit features heavy-duty bars built in-house at WCFab, carrying a lifetime warranty against bending or breaking (to the original purchaser). It utilizes high-quality RockJock rebuildable and greaseable "Johnny Joint" heim connections at the frame, allowing for torsion adjustment and accommodation of changes in rear ride height. A heavy-duty Poly Urethane Bushing is used at the axle connection to reduce noise and vibration. The kit includes Grade 8 hardware for secure installation. The traction bars are professionally powder coated with an epoxy primer base coat for enhanced corrosion resistance.

Installation Notes:
* 100% bolt-on DIY installation option for Crew Cab Short Bed models.
* All other cab and bed configurations require frame modification and welding for proper installation.
* Welding front mounts on all competition applications is recommended for maximum strength.

Important Fitment Considerations:
* If you have a Double Cab Long Bed or Crew Cab Long Bed truck, use part number WCF100876.
* If you have a lift kit and your U-bolts face up instead of down (like factory), use Traction Bar Kit WCF100854.
* If you have a lift kit and your rear lift block is taller than 5 inches or your total lift height is 6 inches or greater, use part number WCF100876.
* For trucks with a significant lift, it is recommended to measure from your axle mounting point to your frame mounting point to ensure proper bar length.
