The SDi Terrain Master 2.1 rear shocks replace the factory rear shocks on the 2018+ Polaris Ranger XP 1000 with adjustable piggyback-reservoir coilovers. This listing is the rear pair, left and right. If you are shopping Polaris Ranger rear shocks because the back of your XP 1000 squats under load or rides harsh, these are the rear half of SDi's Ranger XP 1000 set.
SDi says the typical UTV leaves the factory with low-end emulsion shocks that are over-sprung and offer little performance. The Terrain Master 2.1 answers that for standard-travel machines with high-flow pistons, a low-friction piggyback reservoir, quality seals and bushings and an oversized compression adjuster. Together with the matching front pair, these Polaris Ranger XP 1000 shocks cover all four corners.
Searching for Polaris Ranger 1000 shocks? Check your model first: this set is listed for the Ranger XP 1000, not the base Ranger 1000.
Key Features
- Large bore compression adjuster for a wide, usable adjustment range
- Billet aluminum T6 high-flow pistons with low opening forces for a sensitive, comfortable ride
- Low-friction piggyback reservoir that helps the shock shed heat on long, rough runs
- Race-style quick-adjust preload ring for setting ride height (maximum 1.5 in / 40 mm of preload)
- Machined, anodized aluminum internals with no plastic inside the shock
- Induction-hardened shafts with hard chrome coating to resist pitting and wear
- Barrel-formed, high-tensile lightweight springs built for bow resistance
- PTFE-lined 28 mm spherical bearings with sealed spacers
- 3-piece fully rebuildable seal head for quick, easy maintenance
- Zero Fade Fluid now standard
As a UTV shocks upgrade for the back of the machine, these Ranger rear shocks are among the more adjustable UTV rear shocks for a standard-travel Ranger, and like other Polaris Ranger shocks in SDi's line they rebuild instead of wear out.

FAQ
Is this one rear shock or a pair?
This listing is the rear pair: a left and a right Terrain Master 2.1 rear shock with springs. The front shocks are a separate listing, so order both if you want all four corners.
Will these stop my Ranger XP 1000 from squatting with a loaded bed?
They replace the factory rear shocks with adjustable coilovers. Use the preload ring to set ride height and the compression adjuster to firm up the rear: SDi recommends 1-5 clicks for heavy loads, 6-10 for sportier performance and 11-15 for comfort.
Which rear mounting position do I use?
The SDi manual says to use the outside position (A) on four-seat machines and the inside position (B) on two-seat machines, with the reservoirs up and adjusters facing out and toward the front of the vehicle.
What preload should I run on a two-seat versus a Crew?
The SDi manual lists a 14 in rear spring at 1.5 in preload for four-seat machines and 1.0 in for two-seat machines, with 12-15 in of ride height measured on 29 in tires.
How hard are they to install?
It is a bolt-in swap using the factory shock bolts. You need a floor jack and stands, a socket set, a torque wrench and medium-strength thread lock. Remove the lower bolt, then the upper, swap the shock and torque to factory spec.
Do these fit the base Ranger 1000 or Ranger XP 900?
No. SDi lists this shock for the 2018+ Polaris Ranger XP 1000. The base Ranger 1000 and older XP 900 are not listed.
Why SDi
SDi (Suspension Direct) designs and develops the Terrain Master 2.1 in the US to give standard-travel UTVs real off-road damping. SDi shocks use machined, anodized internals with no plastic inside and a fully rebuildable seal head, which is why riders searching for SDi suspension and UTV shocks look at the Terrain Master line. Dunes 2 Dezert SXS ships side by side shocks like these nationwide.
