Description: The PO1-HDR4 kit features ACT's most popular Heavy Duty pressure plate. ACT Heavy Duty pressure plates utilize an exclusive diaphragm design to increase clamp load, reduce deflection, and maximize clutch life. All diaphragms undergo a four-stage heat-treating process for unparalleled performance. Precision cover stampings ensure rigidity and consistency. ACT's 4-pad rigid race discs are made with high-quality ceramic friction materials. The chrome-moly hub is heat-treated for added strength and durability. The lightweight, rigid design allows for quicker shifts and smooth, trouble-free service. With the 4-pad rigid race disc, engagement is harsher, but shifting is faster. The 4-pad rigid race disc is well-suited for smaller disc sizes in smaller engines.

Great oil but...
Size: 5 Quarts
Great oil. My only gripe is that I need 5.5QT's and single quarts are not available in this weight. Even if it was it looks like a single qt would cost about as much as 5qt's.
