FAQ

Will this kit fit my Turbo S 4 with Walker Evans shocks?

No. This kit is sized for Fox Live Valve shock dimensions. Walker Evans shocks require ZBroz's dedicated Walker Evans Turbo S 4 spring kit.

Will it fit the 2-seat Turbo S?

No. This kit is rated for the 4-seat chassis weight. The 2-seat Turbo S uses ZBroz's dedicated 2-seat Fox LV spring kit.

Will Live Valve still work after install?

Yes. The dual rate springs work seamlessly with the factory Fox Live Valve electronic damping — no controller modifications, no recalibration, no warning lights.

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.

Is installation DIY-friendly?

Yes — plan 2-3 hours per side with basic shock service tools and a spring compressor. Setup instructions are included.
