    Sonnax super hold servo kit 28821-09K dual piston design has 30% more apply area than the OE Powerglide servo. The patented design fits completely inside the case, and the external cover clearance is the same as original servos. The larger apply area will increase band apply force at your current line pressure or allows you to reduce line pressure by 20% to 30% while maintaining the same apply force. Improved sealing throughout reduces fluid loss and is optimized for low friction movement.

    • 30% More apply area
    • Allows line pressure to be reduced, freeing up horsepower
    • Dual seals for piston to case bore
    • Pin-to-case PTFE seal
    • Fits into the same space as a standard servo assembly

    In high performance applications where a larger servo is desired, the Sonnax Servo Kits provide a larger apply area. The Sonnax servo is calibrated to progressively increase band apply force as line pressure increases. Sonnax servos are the perfect upgrade for more holding power without excessively harsh shifts.
