Shock Therapy Dual Rate Spring Kit for Polaris RZR 900 Trail & RZR 900 XC

Shock Therapy Dual Rate Spring Kit for Polaris RZR 900 Trail and RZR 900 XC with Fox shocks

The Shock Therapy Dual Rate Spring Kit replaces the factory coil springs on your Polaris RZR 900 Trail and RZR 900 XC with Fox shocks with a dual-rate spring setup. Shock Therapy calls it the best starting point for upgrading your suspension: the kit is custom tailored to your machine, taking into account driver weight, accessories, terrain and driving style.

WHY A DUAL RATE SPRING KIT

A dual-rate setup stacks two springs on each shock. The softer spring handles small bumps and chatter, and the firmer spring takes over as the suspension compresses further. You get a more comfortable ride on rough trails without giving up support when the hits get big.

• More ride height: Fresh, correctly rated springs lift the machine back up to where it should sit and give you more ground clearance.
• More bottom-out resistance: The firmer rate takes over as the shock compresses, so hard landings and big hits are less likely to slam the suspension to the end of its travel.
• Less bucking: A spring setup matched to your machine and how you ride helps keep the rear end from kicking up over whoops and holes.
• Smoother over chop and chatter: The softer stage soaks up small bumps, washboard and trail chatter before the firmer stage comes in.
• No sagging: Shock Therapy's springs hold their rate, so the machine keeps its ride height instead of settling over time.

FEATURES

• Custom tailored to your machine: Shock Therapy sets up the kit for your machine, taking into account driver weight, accessories, terrain and driving style.
• Made in the USA from CrSi spring steel: Shock Therapy's own springs are made in the USA from high-quality chrome silicon (CrSi) material, so each spring is the exact rate it should be and does not fade or break. The material costs more, and Shock Therapy says it is worth it for function and long life.
• Lifetime warranty on the springs: Shock Therapy warranties the springs for life.
