This is the first of a series of new developments for the bracket racer, dragster drivers specifically, so keep up with what we have going on!

Our latest innovation to come out of our doors is our new extreme adjustment 4-link brackets! We came up with this specifically for the racer whose car needs that fine tuning to maneuver their way down the track. Needless to say, we are talking about your on the edge, high horsepower, and small tire race cars. We've designed these brackets with inserts so you can tune the suspension with even more precision. Included in the kit are inserts that allow for 4-link bar changes up to 1/8". With this kit, you will receive 4 brackets and 8 inserts for the brackets, which allows for you to be able to make a 4-link change in smaller increments than ever before, and without really having to mess with pinion angle, and bar length. Grade 8 bolts, nuts, and washers are also included. Kits are available now!
