To our valued customers,

While this time of year typically involves the chance to shop our products on sale, we had to make the tough decision to postpone any promotional pricing in light of supply chain issues, rising costs and several other factors affecting our business as well as our vendors. We know that our Black Friday/ Cyber Monday sales are very popular and we hope to bring them back once these situations stabilize. We appreciate our customers and want to thank you for continuing to choose Advance Adapters.

With sincere thanks- The Advance Adapters Team


300637 : Short Speedometer Pinion Gear for Electronic Style Housings (#300637)

Starting at: $39.22

Speedometer Pinion Gears

These speedometer pinion gears are the short design used in the electronic style housings found in most of the Jeep TJ New Process 231 transfer cases.

Most of gears that we offer below are imported gears and may require a small modification.  On some of these gears, the square hole on the shaft of the gear may be a snug fit to the speedometer cable.  If this is true in your application, you may be required to sand or file on the square stock at the end of the speedometer cable to fit the gear.  However, most of them fit fine and do not require this modification.
