For heads-up racing machines in many of the sport’s most competitive eliminators, the most minute of suspension adjustments can be the difference between winning and losing, or even making the trip or not. There are so many critical factors, from shock and strut valving to spring selection, four-link bar positions and angles, and so on. And that’s not counting the myriad other factors that go into proper weight transfer to maximize traction. Ride height is also key, and believe it or not, in a Pro Stock car, Pro Modified, Top Sportsman, and the like, just fractions of an inch of change in the front ride height can effect weight transfer enough to completely alter the outcome of a run in given conditions.
To provide but one more tool in the arsenal of a chassis tuner, RJ Race Cars and Quarter-Max devised a threaded adjustable strut mount kit (Part No. RJ-201398), which allows for quick adjustment of your front ride height in the staging lanes, with the car on the ground, using only simple hand tools. The threaded mounts give you total control over the front ride height and the travel in the front struts, and it does so without adjusting the springs by raising or lowering the threaded mounts. RJ provides an adjustable spanner wrench and a strut socket tool with the kit. Once you have the strut mount adjusted to achieve your desired ride height, you simply lock the spanner nut on the mount.
The kit can increase or decrease the amount of travel in the front struts to alter the weight transfer. To increase travel, you simply lower the spring perch down, which will allow more shaft to be inside the strut at ride height. When the car launches the strut will travel further before it reaches full extension. The inner strut mount features a spherical bearing to eliminate all binding for smooth and consistent front end travel.
“Our is the only one that you can easily adjust on the ground…just use a ratchet and your spanner wrench and you can adjust it in just a couple of minute. For Top Sportsman cars, Pro Stock, this is a really important tool for them to have. We put it on every car we build,” Rick Jones says. ”
