FAQ

Will this kit fit my Pro R 4 with Fox Dynamix shocks?

No. This kit is sized specifically for Walker Evans Needle shock dimensions. Fox Dynamix shocks require ZBroz's dedicated Fox Dynamix Pro R 4 spring kit.

Will it fit the 2-seat Pro R?

No. This kit is rated for the 4-seat chassis weight. The 2-seat Pro R uses ZBroz's dedicated 2-seat Walker Evans spring kit.

How much ride height does it add?

Most owners see 1-2 inches of ride height recovery depending on accessories and current spring sag. The dual rate design restores factory-intended geometry.

How long does installation take?

Plan 2-3 hours per side with basic shock service tools and a spring compressor. Setup instructions are included with the kit.

What's included?

Front and rear dual rate springs tuned to the Pro R 4 chassis with Walker Evans shocks. Shocks and shock hardware are not included — the kit installs over your existing factory shocks.
