🛠 Install Tips
- Always replace all clutch springs as a full set – mixing old & new may cause uneven pressure.
- Check clutch plates for glazing or wear while the assembly is open – replace if needed.
- Torque bolts evenly and in a cross pattern to avoid warping the pressure plate.
- If fitting to a tuned engine, consider pairing with upgraded friction plates for maximum performance.
✅ A small upgrade that makes a big difference to clutch performance and lifespan.
