QA1 conical springs are designed so that the lower end sets
on the coil-over shock and the upper end sets in the original spring bucket
in the frame. This allows for the use of a longer and lighter spring for
more stored energy, offering increased weight transfer. Greater durability
is also achieved by locating the spring pressure in the frame and not on
a single stud. The threaded aluminum body allows ride height adjustment
and boasts an easy bolt-in installation. The system includes Promo Star
coil-over shocks, specially designed conical springs and all mounting hardware. |
