Frequently Asked Questions

What does dual-rate do that single-rate doesn't?

A dual rate spring kit uses two spring rates — soft initial for small-bump comfort and progressive higher rate for big hits. The crossover ring lets you tune where the rate transition happens.

Will this fit my Pro XP 4?

No — this kit is 2-seat Pro XP specific. For 4-seat Pro XP 4 with FOX Dynamix shocks, use K25-PL1033-0.

What if my Pro XP came with Walker Evans shocks?

Use K25-PL1030-0 instead. Spring dimensions differ between Walker Evans and FOX Dynamix.

Do I need anything else?

The Pro XP dual rate spring kit with crossover rings includes springs and crossover rings — no other parts needed for installation on stock FOX Dynamix shocks.
