GM41: Made from full 300M
Almost 3 years ago now one of our dealers Thomas Hendrix from Hendrix Engineering had asked us to make a set of axles with different diameters. The reason for this was to help with Wheel hop on certain cars. Now this technology is not something new and it was actually created by both GM and Chrysler for Corvettes and SRT8 models. Like those cars it works quite well. When the torque is applied to the rear wheels through the drivetrain, the axles torsionally twist at a certain rate. On cars with certain types of suspension, they both twist and release simultaneously and cause the wheels to "HOP". With different diameter bars this "wrap up and release" happens at different times helping the wheels to spin. On a street/strip car this is a great thing but keep in mind like the factory ones it will have limitations.
What we have done different is this: Our skinny bar is smaller in diameter than a stock 28 spline 108mm CV would use and its made from 300m. We have rolled the spline onto a ground piece of the material that during the rolling process raises the spline above the center diameter of the bar (this is done with all rolled splines DSS uses). This allows us to make the axle without an internal snap ring so there is no internal groove for a square edged stress riser during torsional shock loading. We then make the Big bar using our 300m material but it's made with a 1-1/2 diameter to balance out the strength. This also has rolled splines so at the edge where the race meets the spline (area of most failures) it is much stronger due to the re-forming of the same material instead of taking away grain structure/material like a cut spine. So if you're running a car up to or around the 1000hp range (keep in mind auto and 6 speed cars will have different effects on Hp ratings) and want to reduce some of the wheel hop this just might be the axle set for you.
Please keep in mind a high performance race car will need the axles to be the same diameter for obvious reasons stated above. Choose Your Parts Wisely.....
1. Our big is big bigger and our little is little all the way down (but uses 300m) 1-1/2 big bar and 1-1/8 small, largest spread in the Industry.
2. rolled spline so the stress riser behind the CV race engagement is stronger by design.
3. Chromoly cages
4. fully insured and in stock
5. fully poweder coated bars
