LCE Pro Performance Clutch Kit: Toyota 1GR-FE (4.0L)
Elevate your Toyota’s drivetrain with the LCE Pro Clutch Kit, engineered for drivers who demand significantly more holding power without sacrificing daily drivability. Our system utilizes a high-performance single-diaphragm pressure plate to ensure consistent clamping force across the entire RPM range.
Performance & Reliability
The Pro Clutch Kit is the ultimate "middle ground" for street enthusiasts and weekend warriors alike. It provides over twice the holding power of a factory clutch while maintaining a comfortable, only slightly firmer pedal feel.
- Enhanced Heat Resistance: Built to handle the thermal demands of technical off-roading and high-performance driving.
- Optimized for Large Tires: This is the ideal upgrade for 4WD vehicles running 31" or larger tires, where extra torque capacity is required to move increased rotational mass.
- Versatile Application: Specifically designed for vehicles with slight-to-moderate performance upgrades that still require everyday drivability.
Technical Specifications
The LCE PRO Pressure Plate delivers a formidable 2,500 lbs of clamping force. This setup is rated for a 300 Ft-Lbs torque limit and 300 HP, providing a massive safety margin over the stock unit.

Clutch Installation Guide: Steps for Success
Following these steps precisely will ensure maximum performance and longevity for your new clutch.
Please note: Failure to follow proper installation or break-in procedures will void your warranty.
1. Preparation & Inspection
- Safety First: Always disconnect the negative battery cable before beginning any major mechanical work.
- Orientation Check: When removing the old clutch, note which direction the spring pack is facing (Engine vs. Transmission). You must install the new disc in the same orientation.
- Cleaning: Thoroughly clean the inner bellhousing to prevent debris from contaminating the new clutch surfaces.
- Component Check: Inspect the clutch fork and pivot bar for cracks, excessive wear, or damage.
2. Flywheel Maintenance
- Surface Prep: You must either resurface or replace the flywheel. A fresh mating surface is mandatory to prevent vibration and premature wear. If the flywheel shows heat discoloration (blue spots), replacement is required.
- Mounting: Apply a small amount of Loctite to the flywheel bolts and torque them in a star pattern (see chart for specs).
- Hardware Note: 2RZ/3RZ flywheel bolts cannot be reused. These are torque-to-yield bolts designed for one-time use only. New bolts are available through LC Engineering.
3. Pilot Bearing & Disc Alignment
- Pilot Bearing: Install the new supplied pilot bearing into the crankshaft. Skipping this step often leads to annoying squealing noises during cold starts.
- Alignment Tool: Use the provided tool to center the clutch disc.
- 20R, 22R/RE/RET, 2RZ, 3RZ: Spring side faces the Transmission.
- 5VZ V6: Spring side faces the Flywheel.
4. Pressure Plate Assembly
- Dowel Alignment: Align the pressure plate holes with the flywheel dowel pins.
- Centering: Ensure the alignment tool stays perfectly centered while installing the pressure plate—do not let it hang on its own.
- Torquing: Use hand tools only to tighten bolts evenly in a star pattern, a little at a time. Uneven tightening can warp the plate, which is not covered under warranty. Remove the tool once secure.
5. Throw-Out Bearing & Lubrication
- Replacement: Install the new throw-out bearing, ensuring it is properly secured to the clutch fork by the two retaining clips.
- Lubrication: Apply a thin layer of white lithium grease or anti-seize to the input shaft splines, pressure plate "finger" tips, and bearing contact surfaces for smooth engagement.
6. Mating the Transmission
- Careful Entry: Slide the transmission onto the engine. Never let the weight of the transmission hang on the clutch disc, as this can cause permanent damage to the disc center.
- Seating: If the input shaft doesn't slide in easily, try rocking the transmission slightly or turning the output shaft.
- Critical: Do not use the bellhousing bolts to "draw" the engine and transmission together. If everything is aligned, they should mate by hand. Forcing it can damage the clutch and engine thrust bearings.
7. Final Steps & Break-In
- Reassembly: Reinstall the slave cylinder and any other removed components. Bleed the hydraulic system according to your factory repair manual if necessary.
- The Break-In: Avoid aggressive driving for the first 500–750 miles. Proper seating of the friction material is essential for a long service life.
