Description

6L80E 6L90E 4-5-6 Clutch Power Hub with 45 Teeth and Shaft Plus PATC Power Pack.

6L80EPH.  6L80E 4-5-6 Clutch Power Hub, Alto Red Eagle Power Pack and Billet Intermediate Shaft. This hub allows for 100% more clutch apply area over stock, 100% more thrust bearing rollers, 150% more lube holes, 29% more inner clutch spline contact area over stock, thick apply plates and a very large Alto Red Eagle Power Pack is included. The Power Pack has 33% more clutches than stock and the lining is 50% wider than stock resulting in 100% more clutch lining area. Combine this with better clutch material and higher pressure and that equals way over 100% more clutch holding power.

PATC is proud to bring you our newest 6L80E transmission improvement. When the 6L80E / 6L90E was first released we knew the possibilities were endless. We actually made the decision to purchase 2 new test vehicles to help us develop this transmission, a 2011 AWD GMC Denali and a 2012 Camaro 2SS. There are 8 major improvements in our new power hub versus the factory hub. We spared no expense on this one. We started our design by eliminating the clutch hub dampener. This increased the contact area between the shaft and hub by 300%. We then designed our shaft out of 300M billet alloy steel, proceeded by heat treatment for added strength. This also ensures that the splines on the shaft have no chance of twisting off or breaking with heavy shock loads. This makes it ideal for hard launches at the track on big boost motors. The hub is made from 4340 HTSR (Heat Treated Stress Relieved) steel, we then have a Zinc Chromate coating applied for increased durability. This is where things start getting really sweet. We have a redesigned Torrington thrust bearing that has 100% more roller bearings than the factory one. 

There are also 150% more oil lubes holes on the hub itself. The inside clutch hub corner has a very large radius machined in versus the factory 90 degree angle. What make this really sweet though is the fact we have machined this one piece billet steel hub to accept a Powerglide clutch. This really opened the door for already race proven clutch material and set-ups that we know works, and yes we have developed a Power Pack for this that is turning the world on it’s ear yet again. We have the most complete and well designed solutions for this shaft and clutches on the market. This was engineered in collaboration with engineers from 2 different race industry manufactures. We know this works and have the scientific evidence to back it up.
