Hyper Shock Absorber Rear for Can Am Defender HD8 HD10 Gas Shock with Preinstalled Spring and Adjustable Preload

Rear gas shock absorber engineered as a direct replacement for Can-Am Defender HD8 and HD10 models. This shock replaces the factory units 706001900 and 706002485 and arrives ready to mount with a preinstalled spring for quicker setup. The preload is adjustable, delivering consistent damping and improved control on rough trails and work-site tasks. Built for Can-Am Defender HD8 (2017-2020) and HD10 (2018), it restores ride height, reduces bottoming out, and enhances overall stability when carrying gear or navigating rough terrain.

What sets this aftermarket replacement apart is its purpose-built performance for real-world trail and farm use. The preinstalled spring eliminates guesswork during install, while the adjustable preload lets you tailor the ride to load, payload, and terrain. This means fewer compromises between on-the-clock durability and on-trail comfort, with predictable damping that helps you maintain traction whether you’re patching fences or cruising fire roads. When you need a rugged, ready-to-install solution, this rear shock delivers reliability you can feel when the trail gets rough.

Installation Notes:

• Support the Defender securely and remove the rear wheel to access the shock mounting points.
• Compare mounting bushings with the factory locations and ensure correct orientation before installation.
• Clean mating surfaces and threaded mounts; apply a light anti-seize compound on bolts if recommended by your service manual.
• Fit the shock with the preload adjuster in a neutral position, then gradually preload up or down to match your load and terrain.
• Torque mounting bolts to the Can-Am service manual specifications; reuse or replace hardware as needed, following the vehicle’s torque sequence.
• Cycle the suspension a few times after installation, then re-check preload and mounting torque to ensure proper seating.

Why Upgrade?

Running a worn rear shock on a Defender compromises control, increases bottoming out, and degrades traction on uneven terrain. This aftermarket replacement restores dampening performance, ride height consistency, and overall stability, delivering reliable handling whether you’re navigating off-road trails or hauling gear on the farm.
