Tech Install: 2002 Silverado 2500HD BDS Recoil Traction Bars
Adding Recoil Traction Bars To Our Big Chevy
We're all familiar with the concept of traction bars, or at least we should be. For those who aren't, here's a quick refresher. As torque is applied to the drive wheels of a vehicle, those wheels turn and propel the vehicle forward. If the rear axle of said vehicle is suspended by leaf springs, which by nature are not rigid, the axle will attempt to rotate forward as well create what is referred to as axlewrap. Under normal conditions, the leaf springs are able to control this motion and limit movement, as too much rotation can break the U-joints, damage springs, or worse. However, when larger tires or additional power are added into the mix, the stress on the leaf springs can become too great.
This is where traction bars enter the equation. By providing support for the axle, these bars work to prevent unwanted rotation. There are a few different kinds of traction bars, ranging from solid bars to splined versions, and even ones with complex linkage designed to prevent axlewrap while not interfering with suspension travel. Desiring to build a better bar—one with all the benefits of a solid bar and none of the negatives—BDS Suspension introduced the Recoil traction bar.
Recoil traction bars use an internal, adjustable, dual-rate spring to provide as much anti-wrap force as is desired by the application while not impeding articulation or wheel travel. Installation of the traction bars is incredibly simple and adjusting them is even easier. Applications are available for Ford, GM, and Ram pickups. We installed a set on our lifted 2002 Silverado 2500HD, which sports 37-inch tires and more than 600 rear-wheel horsepower. The benefit was immediately noticeable in reduced axlewrap and wheelhop, with only a small detriment to ride comfort when cranked up tight. Overall, we're very impressed with all aspects of the Recoil traction bars. Follow along as we take a quick look at the easy install process.
