Frequently Asked Questions

What do traction bars do for leaf springs?

Traction bars are designed to counteract axle wrap, a phenomenon where the torque from the drivetrain causes the leaf springs to twist into an S-shape during acceleration. By bracing the axle housing against the frame, traction bars prevent this twisting, ensuring more consistent power delivery to the wheels and reducing wheel hop.

How do traction bars prevent wheel hop?

Wheel hop occurs when axle wrap causes the rear tires to rapidly gain and lose traction. Traction bars create a rigid link between the axle and the frame, effectively stopping the leaf springs from twisting. This maintains the axle’s position relative to the chassis, keeping the tires firmly planted on the ground and preventing the cyclic loss and regain of traction.

Are traction bars necessary for a daily driver?

For most stock daily drivers, traction bars are not strictly necessary. However, if your daily driver is a truck used for towing, hauling heavy loads, or has increased engine power, traction bars can significantly improve stability, prevent driveline damage, and enhance the overall driving experience by eliminating wheel hop and axle wrap.

Can traction bars affect ride quality?

Yes, some traction bar designs can subtly affect ride quality. While designed to prevent axle wrap, some systems, particularly those with rigid, non-adjustable designs or those heavily preloaded, might introduce a slightly firmer or harsher ride, especially over bumps. However, many modern designs aim to minimize this impact, and high-quality systems often offer adjustability to fine-tune the balance between performance and comfort.

What's the difference between CalTracs and traditional ladder bars?

CalTracs bars, like those from Calvert Racing, are a type of ‘active’ traction bar system. They use a pivot-point design that actively applies leverage against the leaf spring during acceleration, essentially using the axle’s rotational force to push down on the spring, enhancing traction. Traditional ladder bars, conversely, are typically a more rigid, fixed-length design that simply prevents the axle from rotating, often leading to a stiffer ride and less dynamic traction management. CalTracs are generally considered more sophisticated for performance tuning.
