Locking Down the Differential for Real

Under hard acceleration, the rear differential on this platform can shift and rock within its factory mounting, and that movement translates directly into wheel hop, drivetrain shock loading, and power lost to flex instead of forward motion. Torque Solution's Rear Differential Lockdown System addresses that movement comprehensively rather than with a single bushing or brace, tying the differential down more securely across its full mounting points. That thoroughness is what separates a true lockdown system from a partial fix. That's the kind of detail that separates genuine engineering from a basic replacement part.

Built for Serious Power and Serious Use

Constructed from billet aluminum with urethane bushings rather than factory-style rubber, this system is built to handle the increased torque loads of a modified engine without the differential movement that becomes a real problem once you're well past stock power. Less differential movement means more consistent, predictable power delivery to the wheels, especially during hard launches or corner exits. For a genuinely built car, this is a drivetrain upgrade worth prioritizing. It's a small distinction that makes a real difference once you're actually driving on it.

Straight From Subispeed

A comprehensive drivetrain upgrade for 2008-2012 Subaru WRX / 2008-2012 Subaru STI — locks the rear differential down for real rather than addressing just one point of movement.
