....I will be replacing/upgrading all of the key components along with high quality Torrington bearings, moulded pistons from with corresponding return spring, sonnax shell, sonnax supported input drum, reverse drum, pump rebuild with hardened rings, vette servo, pinless accumulators, appropriate valve body modifications with new separator plate and there's probably a couple things I missed but got the main list of things....anyways....I am having a hard time deciding what 3-4 clutch pack to get. I am a bit leery of the 9 pack systems with the thin steels even though they are kolene treated. Would a high quality 6 pack alto red pack with kolene steels be sufficient or perhaps an 8 friction setup would be best. Thoughts and recommendations please |
DO NOT USE Alto Red Eagles in the 3-4 Clutch!!!
Using High Energy Frictions & the Latest OEM Hardened 4L60E Apply & Backing Plates are most important parts to this equation, Besides good Pressure Rise.
