Description
Description
Built for 10R80s that need to hold more power, the Suncoast Category 3 kit pairs extra capacity clutch packs with a Suncoast Pro-Loc valve body. More clutch capacity and more line pressure give firmer clutch apply and quicker converter lockup under heavy towing or added power.
The E clutch goes from a factory 5 clutch stack to 6 clutches for about 20% more capacity and arrives fully assembled and stacked. The F clutch goes from 4 clutches to 5 for about 25% more capacity. The Pro-Loc valve body raises main line pressure by as much as 60 psi, with a built-in bypass that dumps pressure above 420 psi.
Part Number: SC-10R80-CAT3
Running a milder build? The Category 2 kit (SC-10R80-CAT2) covers the clutch upgrades without the valve body. Going bigger? The Category 4 kit (SC-10R80-CAT4) adds an SFI billet flexplate.
