Advance Adapters Atlas Speedometer Housing Assembly - 301506 - ADV301506
82-86 CJ;Replacement for your Dana 300 or Atlas Transfer Case; California Residents: WARNING Just like gold, this is the hard to find now discontinued OEM speedometer pinion gear holder (S-2538608) (NSN 3040011923673) that was used in 1982-1986 Jeep CJ vehicles. In the past this part was only available as salvage or reconditioned part and they were nearly impossible to find. This we know this from our own firsthand experience as this is the primary speedometer pinion gear holder that we use with our Atlas Transfer Cases. We have begun production on our own precision machined billet aluminum version of this elusive item for use with our Atlas Transfer Case, and now it is available to you. Made to factory OEM specs this speedometer pinion holder makes for a perfect replacement for your Dana 300 or Atlas Transfer Case. Note: This speedometer assembly is not needed in 1987-up Jeep vehicles. The drive gear is sold separately (PN300620) due to speedometer calibration for tire size and axle gear ration.
