traction bar

Traction bars have been around for a long time. They are great for reducing or preventing wheel hop and spring wrap-up on cars with rear leaf springs, especially in drag racing situations. Not only do they add to the performance aspect of the car, but also these chrome traction bars look great on the car.

How They Work
Here's how they work: Under normal driving they give a little firmer ride, but under hard acceleration the front of the bars come up and the snubbers come in contact with the leaf springs. This action stiffens the springs and puts more power to the tires, which causes less spring or rear end twist, and more traction on the ground.


The distance from the snubber to the spring can be adjusted by moving the bar back and forth and by moving the snubber from one of the three mounting holes provided to one of the other holes. The more gap between the snubber and the spring, the slower but more aggressively the bar reacts. Less gap means the bar reacts more quickly but less aggressively. In drag racing situations, there usually isn't any gap between the spring and the snubber. This way, the traction bar is working as soon as you get on the gas.

Safe Installation
These universal traction bars will fit most, if not all, older cars with rear leaf springs. For installation, safety is a concern anytime you are jacking up a car and crawling under it. Use heavy-duty jack stands and always remember to block the front wheels. Work on level ground. Keep in mind that the parking brake is attached to the rear wheels, so when you raise the rear wheels there is no longer a parking brake, which is why you should block the front wheels.


Once you've safely installed your traction bars, try a few quick acceleration runs to determine the best setting for the rubber snubbers and your driving style. After you get the bars dialed in, you're ready for some traction action!

traction bars and jack stand
Here are the traction bars right out of the box, and the jack and stands needed for the install.
universal traction bar under spring
Start by placing the universal traction bar under the spring. Now use the jack to position the traction bar in place. Center the bar so all suspension components clear adequately (such as U-bolts, shock mounts, brake lines etc.). The rubber snubber can go into one of three holes depending on how long the stock springs are. Be sure the rubber snubber is fastened securely.
traction bar u bolts over leaf spring
Position the U-bolts that are furnished in the kit over the leaf spring and through the mounting brackets of each bar. Run the nuts up on the U-bolts, using lock washers until they are just snug to the spring. Make sure the leaf spring is centered in the U-bolts.
rubber snubber adjust
Adjust the rubber snubber for a firm or soft ride. Snubber adjustment will vary with type of installation and personal requirements. The suggested adjustment is a half-inch from the leaf spring.
