Leafsprings
Parabolic Mono Leafsprings (PS420-6)

2″ WIDE MONO PARABOLIC LEAFSPRINGS, LIMITED QUANTITIES AVAILABLE

Narrower width allows for better side tire clearance, up to 1/4″

Mopar A-Body, Stock Height

Alternative for aftermarket spring. Substantially lighter than multi-leafsprings.

Parabolic spring design distributes stress along the length of the spring, reducing stress on the arch. Each spring pair is arch verified. Center pins and bushings included.

CalTracs solid Bushings included when ordered directly from Calvert Racing.

NOTE: These springs are designed for DRAG RACING and have a higher spring rate / stiffer ride than stock springs. Springs are dipped in black paint before assembly, but some raw steel may show due to deburring/grinding sharp edges.

Calvert Mono Leafsprings are designed to work with CalTracs to maintain arch. While street driving does not put undue stress on the springs, racing with Calvert springs without a traction device installed may result in bent or de-arched springs.

CalTracs MX (6100-MX)

1960-1963 Ford Falcon

***

To get the most out of your CalTracs, we recommend that your installed CalTracs bars are close to parallel to the ground when fully loaded. Sometimes that configuration is difficult to achieve depending on the mods or equipment you have installed on your drag race car. CalTracs MX helps solve that!

***

Full CalTracs MX kits for cars feature our new MX 3-Hole Adjustable Rear Mounts, MX 4-Hole Adjustment Pivot Plates, and upgraded 9/16” bolt pivot hardware, these kits offer up to TWELVE adjustment settings (compared to two hole adjustable settings in Standard Drag Profile kits) to allow for fine tuning your CalTracs for the best HOOK possible on your racecar. Our new MX rear mount and MX pivot plate designs keep the overall CalTracs assembly set-up above the tire rim line on 15” wheels for track competition compliance and safety, just 1/2” longer than our Standard Drag Profile CalTracs.

EACH KIT ALSO INCLUDES a set of U-BOLTS for stock rear ends. If your vehicle has been modified, please call us so we can sent the correct size. 661-728-9600, M-F, 8am-4:30pm Pacific Time.
