Question & Answers

1 Answered question

Does this fit the 4" bore on the dana 18?

Asked by imagemaker from on

Hello! Yes, this Advance Adapters GM SM465 to Jeep Dana 18/20 Transfer Case Adapter will fit the 4" bore of the Dana 18 transfer case. Thanks!

Answered by Bob H from on

Manufacturer

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
