Buying Guide
What should you consider when upgrading rear suspension?
- Load rating: Match the shock to your rider weight and gear. Higher ratings handle heavier loads but may feel stiffer for lighter riders.
- Stroke length: Longer strokes improve off-road absorption on big hits; shorter strokes save space and weight but may offer less cushion on rough trails.
- Mounting compatibility: Check eye-to-eye length, inner diameter, and mounting hardware to ensure a proper fit with your bike.
- Material and construction: Aluminum alloys provide lighter weight and durability; steel may be tougher but heavier.
- Maintenance: Some shocks require regular fluid checks and spring preload adjustments for optimal performance.
Frequently Asked Questions
- What is “eye to eye” length and why does it matter?
It is the distance between the mounting eyes of the shock. It must match your bike’s mounting points for proper fit and geometry. - Can I upgrade to a heavier shock if I ride with gear?
Yes, but ensure the weight rating aligns with your typical riding load to avoid excessively stiff suspension. - Do these shocks fit all pit bikes?
Most are designed for common mounting sizes; always verify eye-to-eye length and rod diameter for your model. - What is a swing arm kit and when should I consider one?
A swing arm kit with a shock gives a complete rear-end upgrade, often improving stability and alignment on various pit bikes. - Are aluminum shocks better than steel?
Aluminum typically reduces weight and resists corrosion, but quality varies by manufacturing; select based on durability and weight needs.
