Great ride, great stance and traditional styling. Computer engineered to be low while still maintaining proper load capabilities. Just like our front springs, POSIES moly-nylon buttons between the leaves gives a friction free smooth ride.
How to determine what length spring you need
If wishbone is split, perch ends must be heated and bent so that spring perches are at right angle to axle and parallel with spring eyes. Correct distance between perches must be maintained. This must be done before ordering spring so distance between perches can be measured.
