This is a complete 4L60E super rebuild kit containing Alto Red Eagle clutches with the 3/4 clutch pack that includes 8 clutches. This kit will include everything else you need to rebuild your 4L60E transmission. A new filter is included as well as a bushing kit and and thrust washer kit. The band in the kit is a high performance RedEagle band.
Alto Red Eagle® material offers similar mid-point coefficient at high horsepower applications. In addition, the Alto Red Eagle® material gives superior friction wear characteristics at high energy engagements. The leading competitor's material degrades thermally and physically after reaching approximately 2.25 HP/in2.
Below we offer some engineering data collected with this particular clutch.

NOTE: The Lower Lbs./Sq.In. Required to stop the flywheel, the higher the frictional properties.
Results: Pressure required to stop the flywheel on "ALTO RED EAGLE" are slightly lower than "Manufacturer A" and well below "Manufacturer B."
Conclusion: The frictional properties of "ALTO RED EAGLE" are slightly higher than "Manufacturer A" and well above "Manufacturer B."
