The SDI Terrain Master 2.1 rear shock replaces the factory rear shocks on the 2016+ Honda Pioneer 1000, giving owners adjustable compression, a piggyback reservoir and rebuildable internals in place of basic emulsion shocks. It is the rear half of SDi's Honda Pioneer 1000 Terrain Master 2.1 package, so you can upgrade the back end first or pair it with the matching front shock set for the full setup.
SDi built the Terrain Master 2.1 because the typical UTV comes with low end emulsion shocks that are over sprung and offer little performance. These Honda Pioneer 1000 shocks use high flow pistons, a low friction piggyback reservoir, quality seals and bushings, and an oversized compression adjuster, making them a practical Honda Pioneer 1000 suspension upgrade for owners who haul in the bed, carry passengers and trail ride the same machine.
Shopping Honda Pioneer 1000 rear shocks? This is the rear half of the setup. SDi lists it for the Pioneer 1000, and the same part covers Honda Pioneer 1000-5 shocks applications; SDi does not list it for other Honda Pioneer shocks fitments such as the Pioneer 500 or 700.
SDI Suspension (Suspension Direct) builds these SDI shocks as a direct replacement, not a long travel kit. Compared with other aftermarket UTV shocks, Terrain Master UTV rear shocks are one of the simplest UTV shocks upgrades for SxS shocks that ride harsh, and SDi offers the same side by side shocks platform for other utility machines.

Built To Solve: Harsh, Bouncy Rear Ride On The Honda Pioneer 1000
- Factory emulsion rear shocks that feel over sprung and harsh over ruts and washboard
- Rear damping that fades as the stock shocks heat up on long rough runs
- No way to tune the rear for a loaded bed, five passengers or an empty cruise
- Worn stock shocks that cannot be rebuilt, versus a 3-piece fully rebuildable seal head

FAQ
Why does my Honda Pioneer 1000 ride so harsh in the rear?
SDi says the typical UTV comes with low end emulsion shocks that are over sprung. The Terrain Master 2.1 rear shock replaces them with high flow pistons, a piggyback reservoir and an adjustable compression clicker, so you can set the rear softer for comfort or firmer for load.
Will these shocks handle a loaded bed?
They are adjustable for it. SDi recommends 1-5 compression clicks for heavy loads, 6-10 for sportier performance and 11-15 for comfort, and the quick adjust preload ring lets you raise or lower ride height.
Does it fit the Honda Pioneer 1000-5?
SDi lists 2016+ Honda Pioneer 1000 fitment and its preload chart is written for 5-seat machines, which matches the 5-seat Pioneer 1000-5. SDi does not name the Pioneer 1000-6 Crew; confirm with us before ordering for that model.
What preload and ride height does SDi recommend?
SDi's chart uses an 11 in rear spring with 1.0 in of preload on a 5-seat machine, for a ride height of 12 to 15 in measured with 27 in tires. Maximum preload is 1.5 in (40 mm).
How hard is installation?
Bolt-on. With the machine lifted, remove the lower then upper bolts, fit the shock with the reservoir up and the adjuster facing out, and reinstall the stock hardware with blue thread lock torqued to factory spec. Repeat on the other side. The SDi installation manual is attached to this listing.
Should I buy just the rear shock or the full SDI kit?
This listing covers the rear only. If you are replacing all four corners, add the matching SDI Honda Pioneer 1000 front shock set or the complete Terrain Master kit (STM-SS-2531005). Matched front and rear damping gives the most balanced ride.
Why SDI
Suspension Direct (SDi) is a suspension manufacturer and parts supplier for motocross and UTV applications. SDi designs and develops the Terrain Master 2.1 in the US to bring real off-road damping to standard travel utility side-by-sides like the Honda Pioneer 1000, with rebuildable internals instead of throwaway shocks.
Complete Your Honda Pioneer 1000 Rear Shock Upgrade
Confirm your Pioneer 1000 model and year, then add this SDI Terrain Master 2.1 rear shock to your cart. For a balanced ride, pair it with the matching SDI front shock set, and check ball joints and A-arm bushings while the suspension is apart. Questions on quantity or fitment?
