Frequently Asked Questions

What does the dual-rate setup do?

A dual rate spring kit uses two spring rates: a soft initial rate for small-bump comfort and a progressive rate for big hits. Tunable crossover ring sets the transition point.

Will this fit my 2-seat Pro XP?

No — this kit is 4-seat Pro XP 4 specific. For 2-seat Pro XP with Walker Evans, use K25-PL1030-0.

What if I have FOX Dynamix shocks?

Use K25-PL1033-0 for FOX Dynamix-equipped Pro XP 4. Spring dimensions differ between Walker Evans and FOX Dynamix.

Why are these tuned differently from the 2-seat kit?

The 4-seat Pro XP 4 has a longer wheelbase and carries 4 passengers — this Pro XP 4 dual rate spring kit with crossover rings uses different rates tuned for that mass and geometry.

Is this better than buying new shocks?

For value-conscious upgrades, this Stage 1 spring upgrade for Pro XP 4 Walker Evans delivers measurable ride quality without the cost of new shocks.
