FAQ

Will this kit fit my XP 4 1000 with Fox shocks?

No. This kit is sized specifically for Walker Evans Needle shock dimensions. Different OEM shocks (Fox IBP, Fox Live Valve) use different spring lengths and require dedicated kits.

Will it fit the 2-seat XP 1000 or XP Turbo?

No. This kit is rated for the 4-seat XP 4 chassis weight. The 2-seat XP 1000/Turbo uses the dedicated ZBroz XP 1000/Turbo Walker Evans spring kit.

How much ride height does this kit add?

Expect 1-2 inches of ride height recovery depending on accessories, passenger load, and current spring sag. The dual rate design restores factory-intended geometry.

Can I install it at home?

Yes — this is a DIY-friendly bolt-on upgrade. Plan 2-3 hours per side with basic shock service tools and a spring compressor. Setup instructions are included.

Does it work with aftermarket accessories like cages and bumpers?

Yes — the dual rate kit is specifically tuned to handle the added weight of common XP 4 accessories without sacrificing ride quality.
