Frequently Asked Questions

What's the difference between HD Pro Max and Intense Series radius rods?

The HD Pro Max radius rod uses 1.5" Chromoly DOM tubing while Intense Series uses 6061-T6 billet aluminum I-beam. HD Pro Max prioritizes maximum strength with rugged steel; Intense Series prioritizes weight savings and aesthetic with billet aluminum.

Does it offer camber adjustment?

Yes — the RZR Turbo S radius rods use Teflon-lined Heim joints that allow precise camber adjustment.

Will they fit my Turbo S 4?

Yes — the HD upper radius rod kit for Polaris Turbo S fits both 2-seat and 4-seat Turbo S.

Do I need HD Pro Max lower rods too?

For a unified HD Pro Max rear suspension, pair with K45-0650-11. Mixing with OEM lowers works but doesn't deliver the full benefit.

Is installation difficult?

Direct bolt-on with included hardware. Alignment check recommended after install.
