PowerTrain Technology (PTT) Replacement Clutch Disc: Mitsubishi EVO 8 & 9 (1" x 23 Spline)

SINTERED BRONZE METALLIC - PTT's standard friction material is a proprietary sintered metallic material that has been custom blended to meet a variety of different requirements. It is also ground to an extremely fine finish. This eliminates excessive clutch wear and any bedding-in requirement. Standard thicknesses available in this material are .105", .200", or .250" thick. The thickness of the disc for use in your clutch is determined by the type of use it is ultimately put to. Generally speaking, a thicker disc would be selected if the clutch is going to be consistently subjected to higher operating temperatures. All clutch torque ratings shown in this catalogue are for clutches using this material. Metallic friction materials stand up to extreme heat abuse better than organic friction materials.

ORGANIC - Organic friction materials have a softer, more forgiving engagement characteristic. PTT organic discs have a higher coefficient of friction (Cf) than some metallic linings offered. Using the same clamp load (diaphragm spring), the organic material will deliver a higher torque capacity. GENERALLY, you can plan on approximately 400 lb. ft. of break-away torque per 7.25" disc. Organic friction materials lose Cf as the lining temperature goes up. If you get an organic clutch hot, and it slips, let the clutch cool down to avoid costly damage to the rest of the clutch components due to excessive heat.

Replacement Clutch disc pack contains 2 disc.
