Fine Tuning the Shocks
The four GTX shocks greatly in uence handling. Periodic
maintenance may be required to maintain optimal performance.
You can also tune your shocks to your driving style or running
environment. Whenever you rebuild shocks, or make any changes
to the pistons, springs, or oil, always make changes to the shocks in
pairs (front or rear).
To disassemble the GTX shocks:
1. Remove the 2.5x14mm
cap screw from the
lower spring retainer.
Remove the lower
spring retainer and
shock spring.
2. Remove the cartridge/
shock shaft/piston
assembly from the
shock body.
3. Remove the M4
locknut, piston,
4x8mm washer, and
the existing cartridge
assembly from the
shock shaft.
4. Assemble the new
cartridge on the
shock shaft.
Note: The new cartridge must be assembled on the shock shaft. DO
NOT attempt to assemble the cartridge separately and slide it onto
the shaft. This may damage the shaft O-ring and cause a leak.
5. Reassemble in reverse order. Be sure to ll the shocks with 100%
pure silicone shock oil to help prolong the life of the seals. From
the factory, the GTX shocks are lled with 30W shock oil. When
adding shock uid, be sure to allow any air bubbles to escape.
You can tune your shocks by using thicker or thinner viscosity shock
oil, as well as changing the piston that moves through the uid inside
the shock.
Ride height can be adjusted by using the threaded spring retainer.
Adjust the ride height so that the suspension arms are just slightly
above being parallel to the ground. Observe how X-Maxx handles
in turns. Proper setup will add stability and help prevent spinouts.
Experiment with di erent shock oils and ride heights to nd what
works best for your driving style and conditions.
