1955-1957 Chevrolet BelAir
-3″ DROP HEIGHT, 2″ WIDE MONO PARABOLIC LEAFSPRINGS
Alternative for aftermarket spring. Substantially lighter than multi-leafsprings.

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.
