- Performance requirements - Match the clutch to your driving style and vehicle modifications
Reputable aftermarket brands like Exedy, LuK, Sachs, and Valeo offer quality alternatives to genuine Toyota clutch kits.
In most cases, clutch components should be replaced rather than repaired when they show signs of failure. Here's why complete replacement is usually the better option:
- Wear patterns - Clutch components wear as a system; replacing only one part often leads to premature failure
- Labor costs - Since most of the expense is in the labor to access the clutch, it's cost-effective to replace all components at once
- Reliability - Repaired clutch components rarely provide the same performance and longevity as new parts
- Resurfacing limitations - Clutch discs can't be effectively resurfaced once the friction material is worn
The only component that might be repaired rather than replaced is the flywheel, which can often be resurfaced if it's not severely damaged.
