Description: This traction bar kit (WCF100854) is a must - have upgrade for your diesel truck. It fits 1999 - 2022 Cummins RCLB/CCSB/ECSB models and 1999 - 2010 Powerstroke RCLB/CCSB/ECSB models. The kit comes with 60' long bars for Regular Cab Long Bed, Extended Cab Short Bed, and Crew Cab Short Bed trucks. When you increase your truck's horsepower, traction bars prevent axle twisting, which can cause broken u - joints, driveshafts, and twisted axle housings. Our traction bar brackets weld to the axle tube bottom and the front - end frame. At the frame, we use a high - quality RockJock rebuild - able and grease - able “Johnny Joint” heim connection for axle torsion adjustment or when raising/lowering the rear of your truck. At the axle connection, a heavy - duty Poly Urethane Bushing reduces noise and vibration. Grade 8 hardware connects the bars to the frame and axle mounts. The kit is powder - coated in your choice of color, with an epoxy Primer base coat before the final color, increasing corrosion resistance over ten times compared to a standard single - coat powder application. Features: Lifetime warranty against bending or breaking for the original purchaser, 60' heavy - duty bars, HD Poly Bushings, RockJock Johnny Joints, axle and frame side weld - on mounts, Grade 8 hardware, and powder coating with a zinc primer base coat. Notes: Not compatible with 2014 - 2022 Ram 2500 trucks with rear coil springs/linked suspension. For extended cab long bed or crew cab long bed trucks, use part number WCF100855. If your rear lift block is taller than 5' or total lift height is 6' or more, use WCF100855. For big - lift trucks, measure axle to frame mounting points before ordering. For 2011 - 2022 Ford F - 250 and F - 350, see WCF100388 and WCF100399.

Using the Traction Bar Kit: First, make sure your truck is compatible with this kit according to the year, make, and model information provided. If your truck meets the requirements, you'll need to weld the traction bar brackets to the bottom of the axle tube and the front - end frame. Use the Grade 8 hardware to connect the bars to the mounts on the frame and axle. You can adjust the torsion on the axle using the RockJock “Johnny Joint” heim connection at the frame. If you raise or lower the rear of your truck, this connection also allows for easy adjustment. Note: This kit is not suitable for 2014 - 2022 Ram 2500 trucks with rear coil springs or linked suspension setups. If you have an extended cab long bed or crew cab long bed truck, or if your rear lift block is taller than 5' or the total lift height is 6' or greater, use part number WCF100855. For 2011 - 2022 Ford F - 250 and F - 350, refer to WCF100388 and WCF100399. For trucks on a big lift, measure the distance from the axle mounting point to the frame mounting point before placing your order to ensure the bar length works for your truck. Maintenance: The heavy - duty Poly Urethane Bushing at the axle connection helps reduce noise and vibration, but it's a good idea to check it periodically for wear. The powder - coated finish with a zinc primer base coat provides great corrosion resistance, but you can still wash your truck regularly to keep it clean and prevent any potential damage. The RockJock Johnny Joints are rebuild - able and grease - able, so follow the manufacturer's instructions for proper greasing to keep them in good working condition.
