The APR DQ250 Clutch Packs replace the factory transmission’s friction disc and steel plates with an advanced and proprietary design that allows for greater performance. The system goes beyond the norm of simply increasing the disc and plate count, and takes a multi-step approach that not only greatly improves the overall friction engagement area, but does so without sacrificing the total heat-sink material mass of the steel plate. With 40-50% more friction discs, tighter tolerances, carefully specified materials, surface finishes, a proprietary top plate design and more, the clutches hold more torque, prevent premature failure, and provide quick stutter-free high-performance engagement!

Quick facts:

  • More friction discs
    OEM: 9 discs & 18 surfaces (4 large (K1) / 5 small (K2))
    APR: 13 discs & 26 surfaces (6 large (K1) / 7 small (K2))
  • Larger friction disc engagement area
    – Larger OD / smaller ID for a wider engagement area
    – Grove pattern optimized to increase engagement area
    – Grove pattern maintains proper cooling channels
  • Optimized friction material
    – Carefully selected material allows for shutter-free high-performance DCT engagement
  • Improved friction disc tolerances
    – Tighter flatness specifications helps prevent premature wear, drag, hot spotting and warping
  • More steel plates
    OEM: 11 plates (5 large (K1) / 6 small (K2))
    APR: 15 plates (6 large (K1) / 7 small (K2) + 2 integrated top plates)
  • Proprietary top plate design
    OEM: Unused stamped-steel spacer plates
    APR: Thick steel plates with friction mating surface
    – Allows for more friction plates while maintaining critical steel plate thickness
  • Improved steel plate design
    – Thick plates maintain proper heat-sink material mass
    – Heat flattened to stringent flatness requirements
    – Increased hardness to further assist in rigidity
    – Aggressive surface finish matched to friction material
    – Design helps prevent premature wear, drag, hot spotting and warping
    – Provides smooth shutter-free DTC engagement
  • Less clutch destroying heat
    – Better friction means less required clamping pressure, and that means less clutch destroying heat
  • Manufactured in the USA by Quartermaster
    – Multi-plate clutch experts, founded in 1958
