This clutch cover carries the exact Toyota part number 31210-0K310, manufactured to the original equipment specifications used in factory assembly. Built to Toyota's material and dimensional standards, ensuring correct fitment and consistent clutch engagement pressure.
Uses a diaphragm spring that applies uniform clamping force across the clutch disc friction surface, providing consistent pedal feel and progressive engagement.
The pressure plate and diaphragm spring receive factory-spec heat treatment, ensuring the spring retains its clamping force over the service life of the clutch.
Each unit is balanced to OEM tolerances, preventing vibration and chatter that can occur with poorly balanced aftermarket pressure plates.
Mounts directly to the flywheel using the factory bolt pattern. No modifications, adapters, or custom fabrication required.
Each Genuine Toyota clutch cover assembly meets Toyota's original equipment quality standards, including:
- Diaphragm spring load testing - clamping force verified against factory specification
- Dynamic balancing - residual imbalance within OEM tolerance
- Material certification - steel grade confirmed to Toyota material standard
- Dimensional inspection - bolt hole alignment and cover geometry verified against OE blueprint
- Heat treatment verification - hardness and temper confirmed per batch
A certificate of conformance (COC) with batch test data is available for wholesale orders.
