Torco Limited Slip Additive: Eliminate Rear Differential Noise and Chatter

Is your vehicle making a harsh clicking or "chattering" sound during turns? Torco Limited Slip Additive is specifically formulated to silence noisy hypoid gears and eliminate clutch chatter in limited-slip and posi-traction differentials. By modifying the friction between clutch plates, this additive ensures smooth engagement and whisper-quiet operation for your rear end.

Key Benefits for a Quieter Drive

Torco’s friction modifiers are the industry standard for maintaining high-performance differentials.

• Eliminates Gear Noise: Stops the annoying "groaning" or "clunking" sounds coming from your rear differential.
• Stops Clutch Chatter: Smooths out the applying and releasing of clutch plates for a vibration-free experience.
• Improves Clutch Engagement: Optimizes the friction coefficient to ensure your posi-traction unit works exactly when you need it.
• OEM Quality: Meets or exceeds original manufacturer performance specifications for long-term protection.

Which Type of Additive Do I Need?

To get the best results, you must choose the correct formula based on your vehicle's manufacturer. Using the wrong friction modifier can lead to continued noise or improper clutch performance.
