*Dana 300 must be used with a passenger side front axle. Since ground clearance is a concern for most vehicles, Advance Adapters has developed a rotation kit to allow the Dana 300 to be clocked at a higher than stock rotation. The kit allows up to four different rotations than stock. The adapter is .75" thick and includes a new longer input shaft for the Dana 300. The kit retains the proper spline engagement and proper indexing for the Dana 300 transfer case. Kit works on all Jeep Dana 300s with a 23 spline input. Will not work with adapter kits that use a 27 or 32 spline input into a Dana 300. Floorboard and shifter modification may be required.
Advance Adapters got its start in Downey, California in 1971 with a single adapter mating a Muncie car 4-speed to a Jeep Dana 18 transfer case. Eventually headers, overdrives, motor mounts and linkage brackets were added to the offerings to complement their core adapter components. When interest in rock crawling spiked in the mid-1990s, Advance Adapters offered low ratio transmission swaps then switched gears into the ultra-low gear transfer case arena. Today, the company is based in Paso Robles, California and their engine and transmission conversions for Jeeps are in kit form and sold as individual components. Shop Advance Adapters Now
