Bullnosemania Thank you for the question. Depending on the HP of the LS engine, axle ratio, tire size, and what this will be used for (street/light trail, serious off road, etc.), the four speed SM465 is a good heavy duty compound low first gear transmission, no overdrive however. If street/light trail and ~300HP engine, we offer the new AX15. For a higher HP engine and serious off road overdrive you may look into the TR4050, rated at ~600 HP. All these options are adaptable to the Jeep Dana 300 transfer case.
