SunCoast Performance SUNCOAST ALTO 4L80/85E CATEGORY 0 REBUILD KIT - SC-4L80E-CAT0-A

Features and Benefits:

• NEW 4L80E OVERHAUL KIT
• ALTO RED EAGLE CLUTCH PACKS WITH INCREASED CLUTCH COUNT
• HIGH PERFORMANCE KOLENE STEELS
• NEW 4L80E FILTER
• NEW 4L80E BUSHING KIT
• NEW 4L80E THRUST WASHER KIT

 

This is a complete 4L80E super rebuild kit containing Alto Red Eagle clutches with upgraded power clutch pack that includes additional clutches and steels. The additional friction count along with the upgraded steels will improve your 4l80E's torque and horsepower capacity.

This kit will include everything else you need to rebuild your 4L80E 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.

Six Level High Energy Test
On Frictional Properties And Wear

Lbs./Sq. Inch Pressure Required To Stop Flywheel In One Second

Levels	Cycles	OEM Manufacturer A Pressure Required (Lbs./Sq.In.)	OEM Manufacturer B Pressure Required (Lbs./Sq.In.)	ALTO Red Eagle Pressure Required (Lbs./Sq. In.)
1	10	64	70	66
1	100	65	71	65
2	10	72	84	74

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."

Test Schedule and Duration:
Test conducted in six energy levels. Each level consists of 100 clutch engagements at 60 second intervals, from 4600 RPM with a clutch lockup time of one second, the indicated pressure required to stop the flywheel in one second.
