SDI Shock Absorber for Can-Am Defender

SDI (Suspension Direct Inc.) shock absorbers are performance UTV and side-by-side suspension upgrades. They replace basic factory shocks and improve ride quality, control, and durability. The line covers rebuildable Terrain Master 2.1 shocks and E-CLIK electronic adjustable shock systems. Each is designed to handle work, trail riding, and rough terrain.

Key Features:

• High-flow piston design: Valving is tuned for smooth, consistent damping and good small-bump compliance.
• Piggyback reservoirs: Added oil capacity and better heat management help the shocks hold up on long rides and under heavy loads.
• Adjustability: Terrain Master shocks have an oversized external compression adjuster for tuning between comfort and firmness. E-CLIK systems adjust damping electronically.
• Durable construction: Lightweight aluminum bodies resist corrosion. Hard chrome-coated shafts resist wear and pitting. Low-friction seals and quality bushings or bearings keep articulation smooth.
• Serviceability: Terrain Master shocks have a fully rebuildable seal head, so they can be maintained and used season after season.
• Designed in the USA: SDI develops its own suspension products and tunes them for utility-focused side-by-sides.

SDI shock absorbers give a more planted, comfortable, and controlled ride when hauling, working, or running hard on trails. Choose the specific part number for your application from the options listed on this page.
