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 thin wall chromoly steel 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 chromoly 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 chromoly 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 machined from a solid billet of steel and threaded internally and then welded to the chromoly tubing, which further strengthens the 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 chromoly steel threaded tubes for your project in a gold zinc finish. They are constructed from high strength chromoly steel and available in 33 different lengths from 5-inches to 37-inches in 1-inch increments. These zinc finish chromoly steel tubes are threaded to accept 3/4-16 rod ends, bushings, or clevises with left-hand and right-hand threads. This allows the adjusting sleeve to be mounted between two points of adjustment, such as the chassis and rear axle for a Panhard bar mount, among other fitment applications. Rotating the threaded tube moves the threaded ends of your choice inward or outward for adjustment. For the 3/4-16 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 Chassis and Suspension Builds
Wherever you wish to save weight by using a thin wall chromoly steel adjustable threaded tube with swedged ends in your race car, be it for a four-link, Panhard bar, 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 4 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 4 inches for your ends is 18-inches, that is what you will order from the drop-down menu.
Tech Tip: When assembling a tube, each heim end adds approximately 2" to the overall length (assuming the heim is screwed into the tube half way.) If you have a heim on each end of the tube, the working length from eye to eye will be approximately 4" longer overall. As a rule, your tube length will need to be 4" shorter than your working eye to eye length requirement.

Worked for me
Summary: Could be made better with a slot or nut shape to help set it on the fly /fast
Cons: should have a slot for a wrench
Pros: size and thickness

Awesome tubing
Summary: I've bought this tubing twice now in different lengths and each time I'm just as impressed. I use it as a panhard bar for my lowered yukon denali that has a fat diff cover, which no off-the-shelf panhard bar clears it. I needed a smaller OD diameter, but still just as strong as DOM tubing, so I was happy to see pre-threaded chromoly tubing sold by the inch by speedway. I used QA1 offset misalignment spacers (.75 diff side & .25 bumper side vs .50 on both) and cleared the cover by millimeters! The first time, I left the bar as-is and the zinc coating did its job showing no signs of corrosion or rust, even as a daily for well over a year in the pacific northwest. The second version I painted it black just to match my other tubular bars. Never questioned the durability of it, even though I throw the heavy pig around like my third gen camaro and I'm confident it can handle autox duties once I get my denali dialed in.
Cons: No spot for a wrench to hold it in place
Pros: LH Thread side is clearly marked LH threads are clearly marked Popular 3/4" LH/RH threads Pretty light Small OD Well Built / Quality
Yes, I recommend this product.
Solid and exactly as advertised x2
Summary: I have purchased two of these at different times. Both were identical in every way and they work great.
Yes, I recommend this product.
