QA1 is excited to expand its classic Mopar suspension line!

Gerst Tubular Suspension—a manufacturer of classic Dodge, Plymouth, and Chrysler coil-over systems—is now part of QA1.

With this addition, QA1 will quickly expand its line of full-vehicle suspension kits for Mopars. QA1’s state-of-the-art facility in Lakeville, Minnesota enables expanded, efficient manufacturing while maintaining the high quality standards both companies are known for. People will still be able to connect with Carl at events and learn more about his designs throughout his ongoing collaboration with QA1. 

Founded by Carl Gerst nearly a decade ago, Gerst has been producing high-end coil-over systems for classic Mopar cars and D-100 trucks with a focus on innovative designs, top-notch quality and exceptional customer service.

“I hand-picked QA1 when I made the decision to partner with another company,” says Carl Gerst, Founder of Gerst Tubular Suspension. “QA1’s quality standards and manufacturing capability made them the ideal partner. Their team is highly passionate and talented - it’s going to be a lot of fun working together on development projects in the years ahead.”


About Gerst-designed products.

Mopar A, B & E Body Systems
Designed by Gerst, the front and rear coil-over systems eliminate the torsion bars allowing for significantly improved geometry, giving users a more modern driving feel. Popular engine swaps, like the popular Gen 3 Hemi. are also supported with modular motor mounts and plenty of exhaust clearance.

D-100 Systems
Finally, D-100 truck owners have a solution for improved suspension for their classic truck. Easy-to-install front suspension systems convert your truck to a modern coil-over suspension with rack and pinion steering. These Gerst designed front suspension systems are the perfect solution for your ideal lowered stance, ride quality and drivability.
