• NOTE: Calvert Racing Springs are designed for DRAG RACING and have a higher spring rate / stiffer ride than stock springs. Spring halves are dipped in black paint before assembly, but some raw steel may show due to deburring/grinding sharp edges.
• Calvert Split 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 Split Mono Leafsprings are available in Stock height as well as +1″, and 1-2″ drop. Not all ride heights are available on all applications.
• NOTE: If you are running on original springs over 20 years old; your ride height may need to be adjusted to achieve expected results.
