There are several advantages to the Quarter-Max Anti-Roll Bar Kit.

1. Longevity/Stiffness:  In the Quarter-Max kit, the anti-roll arms are designed to weld to the shaft, which eliminates the vertical slop that a bolt-on arm kit will have from day one and will always continue to get more slop as it is used, especially with aluminum arms.

2. Optimized Design:  We have 30+ years of car building experience so we have designed our kits with anti-roll links that feature weld-in threaded tube adapters.  The benefit is after the anti-roll bar has been mounted you can cut and weld the adjustable links that attach to the housing to be the ideal length to achieve optimum 90 degree arm to link angle at ride height so the link will never go past center.

3. Weight:  The Quarter-Max kit will be lighter than most because we use one tube for our anti-roll bar design.  Our design to have the bearing cup fixture welded with the mounting bracket is more expensive for us to manufacture, but is much lighter than adding another outside tube all the way across just for the anti-roll bar to pivot on.

4. Better Materials:  Our anti-roll bar is made with high grade 4130 chromoly steel tubing, which is a stronger grade of steel than mild steel.

5. Higher Quality/Affordable Pricing:  At Quarter-Max we strive to make the highest quality parts in the industry.  Quality over quantity.  All of our kits are designed and manufactured in-house at our facility in Galesburg, IL, USA.  Because we control everything in-house we are able to achieve higher quality standards with all of our kits, and with our experience as an award winning chassis builder, we have the hands-on experience to build the best products for our customers at an affordable price.
