THE PERFECT FIT

Suspension Adjustments

Independent Front Suspension and Front Track Shock 
Spring Preload (RMK/PRO-RMK)

Factory settings, combined with user adjustments to the rear track shock 
spring, should be all that’s necessary to provide the best riding experi-
ence for most riders. The primary adjustment for overall vehicle balance 
is RTSS preload. Perform this adjustment first. See page 50. 

After adjusting the preload, and if desired, additional adjustments can be 
made to the independent front suspension and front track shock preload.

 

When adjusting the front suspension, be sure the springs on both sides 
of the vehicle are at the same adjustment.

Always perform shock spring preload adjustments with the weight of 
the vehicle removed from the shock and with the shock at full extension.

NOTICE: Never exceed one inch (2.54 cm) of preload beyond the factory set-

tings. When decreasing preload, make sure at least two turns of pre-
load are holding the retainer against the spring.

For a softer ride on rough, washboard surfaces, reduce front track shock 
(FTS) spring preload by 1-2 turns.

To improve corner stability, increase front suspension (IFS) spring pre-
load by 1-2 turns on both sides of the vehicle. 

NOTICE: IFS spring installed length must always be set at least 1/4 inch (6 mm) 

less than the free length.
