CYDZSW Universal Rear Shock Absorber 215mm (8.46in) — Adjustable Spring, 2000lb Rated for E‑bikes, ATVs & Mini Motorcycles

CYDZSW 215mm universal rear shock absorber is a durable, adjustable suspension spring designed to fit a wide range of small motorized and pedal vehicles with an 8mm mounting hole and 215mm eye-to-eye length.

This replacement shock combines a high-strength steel body, adjustable damping and spring preload, and corrosion-resistant finishes to refresh worn suspension on electric bikes, mini motorcycles, ATVs, go-karts, pit bikes and many folding or mountain bicycles. It’s engineered to accept a maximum rated load of around 2000 lbs (dependant on installation and vehicle setup) and is sized to replace common 215mm (8.46 inch) rear shocks without modification on compatible models.

Will this shock fit my vehicle?

If your vehicle uses a rear shock with an eye-to-eye length near 215mm (8.46 inches) and mounting holes roughly 8mm (0.31 inch) in diameter, this unit is engineered to be a direct replacement. Always measure the installed shock center-to-center and mounting bolt diameter before ordering to confirm compatibility.

• Eye-to-eye distance: approximately 215mm / 8.46 in
• Mounting hole diameter: about 8mm / 0.31 in
• Common fits: 2-stroke quads, buggies, mini motorcycles, pit bikes, e-bikes, folding bikes, some MTBs
• Check for clearance and orientation in your swingarm or frame

How does the adjustable damping and preload help my ride?

The shock offers adjustable damping and spring preload so you can tune ride height and resistance to compression. Adjustments let you balance comfort and control—firmer settings reduce squat under acceleration and softer settings absorb bumps better.

• Turnable preload to change spring tension and ride height
• Adjustable damping for compression response on varied terrain
• Improves handling when matching shock settings to rider weight and load
• Helps compensate for vehicle modifications or added cargo

What materials and durability features are included?

Manufactured from precision steel components with attention to wear resistance, the shock is built for extended service life under typical recreational use. Surface treatments and quality machining reduce oxidation and friction at moving interfaces.

• High-quality steel construction for strength and rigidity
• Precision parts to minimize play and ensure consistent travel
• Anti-oxidation finishes to protect against rust and elements
• Designed for repeated compression cycles in off-road and urban use

Is installation difficult and what tools are needed?

Installation is straightforward on compatible vehicles and typically requires basic hand tools. The shock is intended as a direct swap for worn units of the same size, avoiding drilling or frame modification in most cases.

• Direct replacement for existing 215mm eye-to-eye shocks
• No drilling or welding required on compatible frames
• Common tools: sockets or wrenches to remove mounting bolts, torque wrench recommended
• Allow time for torque checks and a short test ride to confirm settings

Who is this for: Riders and DIY mechanics who need a robust, adjustable rear shock for small motorized or pedal vehicles—especially owners of electric bikes, pit bikes, mini motorcycles, ATVs, go-karts and folding or mountain bicycles that accept a 215mm shock. It’s aimed at people looking for a cost-effective replacement that restores suspension function and lets them fine-tune preload and damping to suit weight, load and terrain without complex modification.
