When deciding to do a conversion, the first step is to select the type and size of engine you would require. You should consider things such as dependability, power, economy, speed, price range, adaptability, and availability of equipment and parts.

With reference to engine conversions, the Chevy V8 seems to be the most popular option. These adapter kits will adapt your Land Cruiser's transfer case to a GM automatic transmission that will bolt directly to a Chevy V8. Most of the time, these conversions require driveline and floor pan modification.

- Adapter material is 356 T6 heat treated aluminum alloy.

- Kit includes adapter housing, late 4L60E 6 to 4 bolt adapter, 16 spline spud shaft, GM VSS sensor, t-case shifter bracket, retainer, sealed bearing, gasket, nylon lock nut, fastening hardware, and adapter instructions.

Transfer Case: This adapter assembly fits 9/1973 - 7/1980 16 spline transfer cases (originally mated to a 4 speed transmission). The drive gear has 16 internal splines and a diameter of 1.259”. Bolt pattern is the same as the earlier 3 speed transfer cases.

Transmission: The adapter kit is designed for exclusive use with 1997 & up 2wd 4L60E / 4L65E. These 4 speed overdrive transmissions are featured in late model GM trucks. The output of this transmission has a 6 bolt hex pattern. An extra adapter is included in this kit that will convert the output to a 4 bolt pattern which is compatible with the adapter housing.

*Note: It is not practical to adapt an automatic transmission to the Land Cruiser's 6 cylinder engine. The length of the engine, coupled with the length of the automatic transmission causes problems with the fuel tank, transfer case linkage location, and driveshaft angles.

Frequently Asked Questions

When can I expect to receive my order?

We strive to ship orders as quickly as possible but orders can take as long as 4 weeks due to item availability. However, this is an estimated time. Due to a high volume of orders we receive, we cannot expedite the process as this would be unfair to other players and clubs. We process orders in the order as they are placed. Those that place their order early on will most likely receive their order before those that place their order at a later date.
