Anthem Off-Road. In a street driven application, you never want to limit the ability of the rear axle to move up and down only its ability to rotate. Believe it or not, traction bars can actually improve the braking ability of a truck. While acceleration without traction bars forces the pinion angle upward, heavy braking causes the opposite to occur the pinion angle is forced downward. Traction bars keep the pinion angle the same no matter the circumstance.
One easy way to tell if a truck needs traction bars is how the rear axle and suspension behaves while on a chassis dyno or, as many have done, throw the GoPro under the truck and take a test drive. During a dyno pull, where maximum horsepower and torque is being sent to the rollers, axle wrap will be in its most prevalent state if it exists at all.
Driveshaft plunge and an upward-pointing pinion angle are key items to look for. An up and coming player in the traction bar market is Flight Fabrications. The company builds ladder bar-style traction bars using 1. Arguably no other sport wreaks as much havoc on a driveline than sled pulling axleshafts, differentials, driveshafts, U-joints, pinion yokes, etc. As a general rule of thumb, they are needed as soon as extra horsepower has been added to the mix.
One such part is a traction bar. Its bushings are equally vulnerable to displacement. Fortunately, a traction bar works to prevent the axles from slanting, which secures the bushings from slipping whenever the car is in motion.
The connectivity of these parts is paramount for a well-performing car. A suspension system has several main functions. Springs are the core parts that assist the performance of these functions. Leaf springs especially function as support while absorbing bumps on the road. Interestingly enough, leaf springs were used on carriages and carts before the invention of cars and trucks. These days, leaf springs are the norm within modern SUVs, vans, and large trucks, but some older cars still have these springs in their suspension system designs.
Leaf springs can become bent or deformed and cause axle wrap. This is where the employment of traction bars comes into play.
For a traction bar, everything you need to know has to do with their objective: prevention. The design of traction bars is purposeful to prevent axle wrap. Traction bars are prevention devices that mount to the rear axle of a vehicle and are connected elsewhere to the frame. How do they do it??
Well they act as a brace that keeps the axle from moving at all. The rear attachment point is pretty much standard. Almost all bars bolt up with the factory u bolts new ones of course. The front attachment is where they differ but ill discuss that later.
What the bar does is take the force from the axle trying to move forward and transmit it to the frame in the fron tattachment point. At the same time some of this force goes back to the rearend and pushes it into the ground giving you more traction, thus why they are called traction bars. At the same time it also prevents your axle from doing its own thing compared to the frame which also gives more traction and prevents driveshaft failure which is usually caused by bounching.
The bouncing effect comes from the sprin deforming and snapping back, ones this starts its nearly impossible to stop without letting off. Now there are all kinds of different bars but here are the most common. Short bars such as caltracs use the front spring shackle as an attachment point.
These work well for drag racing I am told but I havent seen many successes in pulling with them, and im one to testify. The kinda long bars usually bolt right where the frame bends up in the rear which is just after the rear cab mount. This is a good setup for pulling but keeps alot of the force going to the rear tires.
The Long bars like what I run connect way up front. Mine connect in between the trann x member and the t bar x member.
These bars take a lot of the force and use it to lift the front end.
