Shock Spring Seat Adjustment
The front shocks, on vehicles
without hydraulic front lift and rear
shocks, have threaded spring seats
that allow adjustment of the preload
on the coil springs. The vehicle
corner weights can be adjusted for
track use. If the vehicle trim height
is modified, it should be returned to
normal trim height before street use.
The spring seat can be adjusted
approximately 20 mm (0.8 in) up or
down from the nominal position.
Each complete turn of the spring
seat will change the vehicle height
approximately 1.5 mm (0.06 in).
When adjusting the seat to the
upper limit, lift the dust boot and
ensure the seat does not thread off
the center support tube (stop
adjustment when threads no longer
visible). When adjusting the seat to
the lower limit, leave approximately
10 mm (0.4 in) of thread visible for
the lower lock nut to have full thread
engagement.
To adjust the lower spring seat:
1. Raise the vehicle so the tires
are completely off the ground.

2. Loosen the lower spring seat
lock nut (2).
3. Thread the lower spring seat
lock nut (2) downward off of the
threads to its resting location
on the shoulder of the center
support tube.
4. While holding the center
support tube holes, turn the
spring seat (1) upward to
increase spring preload,
or downward to decrease
spring preload.
