About Us


John drove his 1968 Cobra Jet Mustang at the 1991 Winston World Championships, taking the title and setting the sportsman stock race world on fire. John is often crediting with reigniting interest in stock car racing at that moment.

Learning from other drivers and sharing what he himself learned with other enthusiasts. John opened Calvert Racing Suspensions in 1991 out of his garage. The Calvert plant is now located in Lancaster, California, and holds several patents. They manufacture the CalTracs Traction Bars, Three-Link Kits, split mono leaf-springs, shocks, wheelie bars, and other suspension race parts designed specifically to improve racing times and address some of the issues that stock car racers face in street, strip or drag racing.

Calvert Racing Suspensions tests every single shock, both front and rear, each threaded insert for CalTracs systems, wheelie bars, and all manufactured and custom parts to ensure quality, consistency, and spec accuracy.

Installation Guides, most of them illustrated, are included for CalTracs, CF/CR Series shocks, Adapters, Hangers, Perches, Lowering Blocks, and other misc. parts.
