The SDi Terrain Master 2.1 rear shocks replace the factory rear shocks on the 2024+ Polaris Ranger XD 1500 with adjustable piggyback-reservoir coilovers. This listing is the rear pair, left and right. If you are shopping Polaris Ranger 1500 shocks because the back of your XD 1500 squats, bounces or feels harsh with a loaded bed, this is the rear half of SDi's Ranger XD 1500 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. Paired with the matching front shocks, these Polaris Ranger rear shocks complete a four-corner Polaris Ranger suspension upgrade.
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 the other Polaris Ranger shocks in SDi's line they are fully rebuildable.

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 XD 1500 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 mounting position do I use on a two-seat or Crew?
The SDi manual says to use the outside rear mounting position (A) on four-seat machines and the inside position (B) on two-seat machines, with the reservoirs up and adjusters facing out toward the rear.
Do these fit both the two-seat and Crew Ranger XD 1500?
SDi lists the shocks for the 2024+ Polaris Ranger XD 1500 and ships the springs at the four-seat setting. On a two-seat machine, set rear preload to 0.625 in per the SDi manual instead of 1.0 in.
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.
Should I buy the rear pair or SDi's complete kit?
If your front shocks are still good or you are spreading the upgrade out, the rear pair lets you start where the load sits. For all four corners at once, add the matching SDi front pair or look at SDi's complete Ranger XD 1500 Terrain Master set in the related products.
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.
