How to find the right Bike Suspension Service Parts AI guide
Written by an AI model from its trained knowledge.
What the AI looks for in Bike Suspension Service Parts
- Exact model and year match
- Order seals and damper parts by fork or shock model, model year and damper type, not by brand alone. Internals change between years and dampers even within the same product name.
- Stanchion diameter
- Dust wipers and foam rings must match the stanchion size exactly, for example 32, 34, 35, 36 or 38 mm. A seal sized for the wrong diameter leaks or binds immediately.
- Oil type and weight
- Use the manufacturer's specified oil and volume for the lowers, the damper and the air spring. The wrong oil changes damping speed and can damage seals.
- Shock eyelet bushings and hardware
- Match the eyelet bore, hardware width and bolt diameter for each mount. Worn or wrong-size hardware causes knocking and play in the rear end.
- Service interval
- Follow the manufacturer's riding-hour schedule for lower-leg service and for full damper service. Regular lower-leg service is cheap and prevents stanchion and bushing wear, which is costly to fix.
Brands that matter
- RockShox: OEM service kits are sold by fork or shock model and year.
- Fox: OEM rebuild kits, plus its own branded suspension fluids.
- SKF: Aftermarket low-friction seal kits for many forks.
- Enduro Bearings: Aftermarket seals and shock bushing hardware kits.
- Motorex: Suspension fluids and greases widely used in bike service.
- Maxima: Suspension oils that some manufacturers specify.
What to avoid
- Generic seal kits that do not state the stanchion diameter and the compatible fork models.
- Mixing oil brands or weights in a damper.
- Opening nitrogen-charged or IFP-pressurized dampers without the correct tools and charging equipment.
Questions
Should I service the lowers myself?
Lower-leg and air-can service is a common home job with a seal kit, the specified oil and basic tools. Damper rebuilds on pressurized shocks are better left to a service center.
