The Science Behind Shock Therapy’s Shock Forks for the Polaris RZR Pro R

Polaris RZR Pro R Shock Fork

By David Crowley

Contrary to popular belief, shock forks on a Polaris RZR Pro R and Turbo R don’t typically break during a crash. The weakest point in the shock system is actually where the shock shaft tapers down to the threads where it connects into the fork, snapping the shock shaft itself.  Likewise, there isn’t really any need for a stronger fork (which is the only benefit provided by other aftermarket forks) as it doesn’t address the weakest point in the system. 

Shock Therapy’s Shock Forks for the Polaris RZR Pro R & Turbo R come with an ingenuitive design that’s even currently patent pending. Their shock fork is the only one on the market that supports the shaft and prevents it from snapping or shearing off –– something which only happens when a ball joint breaks or you clobber a rock and rip off a wheel, as seen below.

Shock Therapy improved the typical design to provide even more strength and support where the system needs it most. With the same shaft and same thread diameter, the design of the shock forks provides support by surrounding the shaft to prevent shear –– reinforcing the shock shaft at the weakest part of the system. Additionally, the two-piece spring perch (which also works with stock shock forks) causes a press fit on the fork which tightens it to the shaft for extra security.

The shock forks from Shock Therapy utilize stronger material than stock, and the design produces no loss in suspension travel. Moreover, adding other Shock Therapy components to your vehicle can help provide reinforcement for the whole suspension system, such as Tie Rods.
