Pro Metallic Clutch Kit: Toyota 1GR-FE (4.0L)
Engineered for the absolute extremes of competitive racing and heavy-duty off-roading, the LCE Pro Metallic Clutch Kit is designed to eliminate slip and handle the high-torque output of the 4.0L 1GR-FE. While other designs rely on "gimmicks," our single-diaphragm heavy-duty pressure plate delivers maximum, consistent clamping force across the entire RPM range.
Race-Proven Holding Power
This kit combines our highest-rated pressure plate with a bulletproof dual-metallic friction disc. It is the definitive choice for:
- Drag strip & circle track racing
- Extreme rock crawling
- Competition-level off-roading
LCE Pro Performance Specifications
The LCE PRO Pressure Plate is engineered to provide a massive 2,500 lbs of clamping force. This translates to a robust 475 Ft-Lbs torque limit and a 475 HP rating, ensuring your drivetrain can handle extreme power demands without slipping.
Complete Installation Kit
Each LCE Clutch Kit is a comprehensive package featuring all-new components:
- Heavy-Duty Diaphragm Pressure Plate
- Dual-Metallic High-Friction Disc
- Premium Throw-out Bearing
- Alignment Tool
Critical Application Notes
- Engagement Style: This is a highly aggressive clutch. It is designed for racing and competition; it is not recommended for daily street use due to its rapid engagement and firm pedal feel.
- Vehicle Compatibility: Fits North American-produced trucks only.
- Exclusions: Not compatible with TDI engine conversions.
- 6-Speed Manual: Specifically configured for the 1GR-FE 6-speed transmission.
- The LCE Advantage: From street performance to the grueling conditions of professional competition, our kits are engineered for those who demand more "grab" and absolute reliability. Simply the best.
-Note: This specific kit is designed for the 6-speed 1GR-FE, which does not utilize a pilot bearing.

Clutch Installation Guide: Proper Assembly & Break-In
Following these steps precisely ensures maximum performance and longevity for your new LC Engineering clutch.
Failure to follow these installation or break-in procedures will void the product warranty.
1. Preparation & Inspection
- Safety First: Disconnect the negative battery cable before beginning work.
- Orientation Check: When removing the old clutch, note which direction the spring pack is facing (Engine vs. Transmission). The new disc must be installed in the same orientation.
- Cleanliness: Thoroughly clean the inner bellhousing. Debris on the clutch surfaces can cause premature failure.
- Inspection: Check 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 required to prevent vibration and abnormal wear. If the flywheel shows heat discoloration (blue spots), replacement is recommended.
- Installation: Use a small amount of Loctite on the flywheel bolts.
- Hardware Note (2RZ/3RZ): Flywheel bolts for 2RZ/3RZ engines are Torque-to-Yield and cannot be reused. You must install new bolts.
- Pattern: Always torque flywheel bolts in a star pattern (see torque chart).
3. Pilot Bearing & Disc Alignment
- Pilot Bearing: Press the new supplied pilot bearing into the crankshaft. Skipping this step often leads to "squealing" noises during cold starts.
- Alignment: Use the provided alignment tool to center the disc.
- 20R/22R/RE/RET/2RZ/3RZ: Spring side faces the Transmission.
- 5VZ (V6): Spring side faces the Flywheel.
4. Pressure Plate Installation
- Alignment: Line up the pressure plate holes with the flywheel dowel pins. Keep the alignment tool centered and supported during this process.
- Torque Sequence: Tighten bolts evenly in a star pattern, a few turns at a time.
- Crucial: Use hand tools only for the pressure plate. Uneven tightening or using an impact wrench can warp the plate, which is not covered under warranty.
5. Throw-out Bearing & Lubrication
- Replacement: Install the new throw-out bearing using the two retaining clips on the clutch fork.
- 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 to ensure smooth engagement.
6. Transmission Reassembly
- Handling: Slide the transmission into place carefully. Never let the weight of the transmission hang on the clutch disc, as this will bend the disc center.
- Mating: If the input shaft resists, slightly rock the transmission or turn the output shaft.
- PROHIBITED: Do not use the bellhousing bolts to "pull" the transmission and engine together. This causes severe damage to the clutch and engine thrust bearings. If they do not mate by hand, the alignment is incorrect.
7. Final Steps & Break-In
- Hydraulics: Reinstall the slave cylinder and bleed the system per the factory manual.
- Break-In Period: Road test the vehicle and avoid aggressive driving, high-RPM shifts, or heavy towing for the first 500–750 miles. Proper seating of the friction material is vital for a long service life.
