These R Series Pro Coil systems from QA1 are engineered just for drag racing. Their R Series shocks offer firm compression with a wide range of rebound adjustment for front drag racing applications. Also featured are specially designed conical springs that allow the use of a longer and lighter spring for more stored energy, offering increased weight transfer. Greater durability and safety also result from locating the spring pressure in the frame and not on a single stud. Available for both small and big block applications, these systems are ride height adjustable, and give you unmatched performance on the strip.
