Why the 4-Seat Turbo R Demands Its Own Dual Rate Kit

The Polaris RZR Turbo R 4 Seater combines the highest power output in the RZR lineup with the highest passenger capacity — creating unique spring rate requirements that no 2-seat or lower-power kit can address. At Turbo R speeds with 4 passengers, a spring that's correctly rated for 2 passengers will feel too soft under full load, leading to excessive body roll and bottoming. A spring tuned for a 2-seat Turbo R will feel too stiff when the machine is lightly loaded. The AllThingz UTV dual rate kit solves this with a progressive spring rate curve that works correctly across the full load range of the 4-seat Turbo R — soft enough for 1-2 passengers, firm enough for a full crew at speed.

My 4-seat Turbo R was brutal with a full crew at speed. This dual rate kit transformed it — plush over small stuff, still handles big hits with everyone loaded up. — Verified Buyer

Installed the full kit in about 90 minutes. Every passenger noticed the difference immediately. Best suspension upgrade I've done on the Turbo R. — Verified Buyer
