Powerflex Transfer Case Bushing Insert - Performance Series

Product Details

Drivetrain deflection is a direct threat to hard launches and fast track exits. Under aggressive load, the factory xDrive transfer case mount twists and deflects significantly inside its rubber voids. This deflection delays throttle response and places heavy angular stress on the driveshafts and flex discs. The Powerflex PFF5-1526P Transfer Case Insert is a track-targeted solution designed to anchor the transfer case on E9X, E83, and E84 xDrive platforms.

Formulated from a track-proven 80A durometer Purple polyurethane, this insert is specifically engineered for tuned street and occasional track vehicles. By filling the factory bushing's compliance voids, it significantly increases torsional stiffness in the primary power path. The result is zero-compromise torque transfer, sharper manual shifts, and completely predictable acceleration at the limit. (Note: As a performance-focused component that couples the transfer case closer to the chassis, a minor increase in cabin NVH, particularly at idle, is to be expected).

Technical Features:

• 80A Durometer Polyurethane: Engineered specifically to restrict high-torque transfer case rotation.

• Direct Void-Fill Design: Locks down the factory mount without requiring a full bushing press-out or removal.

• Stabilized Driveline Alignment: Prevents angular misalignment of the driveshafts under heavy launch loads.

• Track-Validated Longevity: Impervious to oil degradation and thermal heat cycles that kill factory rubber.
