Parabolic Mono Leafsprings (PS640-4)

2″ WIDE MONO PARABOLIC LEAFSPRINGS, LIMITED QUANTITIES AVAILABLE

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

1964-1966 Ford Mustang, Stock Height

1967-1973 Ford Mustang, -1 In Drop

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.

Calvert’s Mono Parabolic Leafsprings are available in Stock height as well as +1″, and 1-3″ drop. Call for other/custom ride heights.

Please call if you are running on original or springs over 20 years old; your ride height may need to be adjusted to achieve expected results.
