Advance Adapters NV4500 Transmission & 3.8:1 Atlas ll Transfer Case Super Combo Kit for 89-93 Jeep Wrangler YJ (with 4 Cylinder & Manual Transmission)

It's plain & simple. Buy both the Atlas II and the NV4500 Transmission and save over $300! It's the perfect time to install both while the skid plate is down and your project is under way. You'll have the strongest drivetrain system available on the planet.

ATLAS II TRANSFER CASE (Ultra-Low 3.8:1 Gear Ratio): The solid one-piece case design is manufactured from 356-T6 heat-treated aluminum alloy. The massive gears are helical cut and synchro-equipped for quiet performance and shift-on-the-fly capability.

NV4500 TRANSMISSION: Replace your balky AX15 or AX5 with a New Venture NV4500 Transmission. The NV4500 is used in both the GM & Dodge truck applications. There have been numerous NV4500 transmission conversions in almost every type of 4WD vehicle due to its nearly indestructible design. The factory transmissions used in Wranglers have proven to be inadequate for aggressive off-road driving. They do not hold up over time under extreme conditions.
