ADJUSTING SPRING CROSSOVER (DUAL SPRING ONLY)
The spring crossover point is an important tuning parameter. A softer initial spring rate
offers improved traction and hook-up while a higher spring rate deep into travel helps to resist bottoming on
jump landings.
As a rough guideline, the spring crossover point should be as deep into travel as possible without
experiencing excessive bottoming. The crossover point is defined as a percentage of the total shock travel.
The factory setting for the spring crossover point is 55 percent. This means that a 5-inch travel shock would
have the crossover point at 2.75 inches (5.0 inches x 0.55) into the shock travel.
In order to calculate your spring crossover ring placement, you need to know four important pieces of
information:
1.
Metal-to-metal shock travel in inches (measure before spring installation).
2.
Main spring rate (lb-in) - marked on spring (see Reading the Spring Rate).
3.
Tender spring rate (lb-in) - marked on spring (see Reading the Spring Rate).
4.
Desired crossover point (as a percentage).
The shock travel is the exposed length of the shaft (including the bump stop) when the shock is fully
extended. It may be easiest to measure before you install the shock.
Some shocks use external spacers below the bump stop to limit travel. Do not include the spacer length as
part of the travel.
The crossover point is a tunable parameter. It should be between 45 and 65 percent.

STEP 1
Set ride height as described on page five.
STEP 2
Once you have established the correct preload, jack up the UTV and place on a stand to keep the
wheel off the ground. The shock should be fully extended.
