GM TURBO 350 TRANSFER CASE ADAPTERS

GM TURBO 350 TRANSFER CASE ADAPTERS
'79-'83

The '79-'83 Toyota requires using a transfer case adapter that is 3-3/8" long. This precision machined, one-piece adapter provides precise alignment of the transmission/transfer case. The two units are coupled together with an exclusive coupler/internal support bearing assembly to ensure a leak-free installation and eliminate vibration problems. We have sold many replacement adapters to customers who made the mistake of purchasing a 2-piece style adapter first!

If you have a 4WD TH350 transmission you may purchase the adapter, less shaft, at a reduced price. This adapter, when used for V8 installations in 1984-1995 models, should eliminate driveline modifications.

GM 700R / 4L60 OD
TRANSFER CASE ADAPTERS

GM 700R TRANSFER CASE ADAPTERS

The 700R-4 transfer case adapter is becoming popular due to a first gear ratio that is 17% lower than the Turbo 350 transmission, plus the advantage of a 4th gear that is a 30% overdrive. This greatly reduces engine rpm at highway speeds and will increase fuel economy. Chevy V8 conversions will require minor driveshaft modifications. The 2nd version 4L60-E 1997 and later has a removable bell housing and requires an additional adapter. This adapter converts the hex bolt to a square pattern.

FORD C4 TRANSFER CASE ADAPTERS

The C4 transmission is an extremely compact and rugged unit. This adapter, when used in '84-'95 trucks, eliminates both driveshaft modifications and transfer case mount relocation. The C4 adapter features an exclusive design, coupler/internal support bearing assembly to ensure a smooth, vibration-free installation. The adapter, when used in '79-'85 trucks and 4Runners, requires minor driveshaft modifications.
