Lethal Performance Clutch Kits

[Insert action movie trailer voice] When raw power collides with precision engineering, every component must perform without compromise... In all seriousness, Lethal Performance Clutch Kits are designed to harness and transfer every ounce of torque—from street-friendly 500hp builds to full-throttle 1000hp monsters. Utilizing advanced materials, innovative bonding techniques, and rigorous manufacturing standards, our clutch kits deliver blistering performance with rock-solid durability.

Lethal Performance offers a clutch lineup engineered to suit every level of Mustang power. The Street Fighter 525 delivers smooth, stock-replacement reliability for naturally aspirated builds with its Carbon/Kevlar friction disc and 525 ft/lbs torque rating. Step it up with the Street Warrior, a robust, SFI-approved kit featuring dual-faced ceramic discs built to handle 700hp and 700 ft/lbs, perfect for turning everyday driving into a track-ready experience. For those who demand even more, the LPX and LPXHD twin-disc systems combine advanced Carbon/Kevlar technology with precision engineering to manage 800 to 1000 ft/lbs of torque, offering exceptionally smooth engagement and enhanced durability under extreme conditions.

When it comes to choosing a clutch kit for your build, it’s not just about upgrading for the sake of power—it's about matching your clutch to your build. A kit that's engineered for a 500hp setup won't hold up when your engine cranks out 800hp, and a clutch designed solely for street use might buckle under the drag strip’s relentless abuse. Choosing the right performance clutch ensures every gear change is smooth and every launch is optimized, whether you're carving through city streets or dominating the track.
