Swedged Tubing Provides Similar Strength with Less Weight

Weight is the enemy of a race car. Any time you can save weight without reducing integrity or creating an unsafe situation you will benefit. Utilizing aluminum tubing for such things as control arms, Panhard bars, steering linkage, and more are all great ways to not only save weight but allow your suspension and steering to react faster to changes in the track surface, which ultimately keeps your race car’s tires in contact with the racing surface for precise throttle, braking, and steering control that can put you in the winner’s circle.

One easy way to save weight is to replace heavy wall steel suspension and steering tubes with thin wall steel versions that utilize a swedged end. Swedged tubing is the perfect upgrade to these suspension and steering pieces when sized properly for the application. Swedging the ends of the steel tubing shrinks the outside diameter down, which thickens the wall of the tubing in the area where threads are created for the heim joint, bushing, or clevis end piece to be installed. This critical area is cold formed, which further strengthens the steel tube. Swedged steel tubes are lighter than their non-swedged steel counterparts while meeting the same strength requirements.

Multiple Lengths to Fit Any Race Car Application

We offer these super strong steel threaded tubes for your project in a gold zinc finish. They are constructed from high strength steel and available in 7 different lengths from 4-1/2-inches to 7-1/2-inches, in 1/2-inch increments. These gold finish steel tubes are threaded to 5/8-18 with right-hand threads on one end and 1/2-20 left-hand threads on the opposite end for building or repairing adjustable upper control arms. This allows the adjusting sleeve to be mounted between two points of adjustment, such as the upper ball joint collar and a traditional rod end. Rotating the threaded tube moves the threaded ends of your control arm inward or outward for adjustment. For the 5/8-18 and 1/2-20 thread ends these steel sleeves utilize this equates to roughly 1/8-inch of adjustment for each full rotation of the hollow threaded tube.

Great for IMCA Modified and Sport Mod Builds

Wherever you wish to save weight by using a thin wall swedged steel adjustable threaded tube in your race car, be it for a steering linkage, chassis support, or elsewhere, it is easy to figure out exactly what you need. Simply measure the center-to-center distance of your two adjustment or mounting points, subtract 3 inches for your rod ends, bushings, or clevises you choose and then order the closest length to that measurement. So, if your final measurement after subtracting the 3 inches for your ends is 5-inches, that is what you will order from the drop-down menu.
