I've got a 2017 Chevy 3500HD Regular Cab with a 7" lift. Are the 70" traction bars or the 58"?

Standard cab long bed trucks require the 58" traction bars. One thing to remember is that the lift can affect the traction bar length. When speaking to the lift height, the rear lift is critical to traction bar length and not the front. Most lift kits will raise the rear of the truck about 2" less than the front. For instance, a 7" lift will generally lift the back of the truck 5". Our traction bars are adjustable to accommodate up to 4" of rear lift. If your truck needs custom length bars, please call us to discuss your options.
