THE PERFECT FIT

IQ Front Suspension Adjustments

Shock Valving

Walker/Evans shocks can be revalved if spring preload alone isn’t

sufficient and further adjustment is desired to control suspension

stiffness.

WARNING

Changing shock valving on Walker/Evans shocks requires special

tools and a sound knowledge of mechanical theory, tool use, and

shop procedures to perform the work safely and correctly.

Shocks contain high-pressure nitrogen gas. Use extreme caution

when handling high-pressure service equipment. We recommend

that this work be performed by a Polaris dealer.

Front Springs

For models without externally adjustable or revalvable shocks, the

front springs can be changed if spring preload alone isn’t sufficient and

further adjustment is desired to control suspension stiffness. See your

Polaris dealer for more information.
