Get your R154 rebuild kit from the team whohas offered R154 transmission support the longest! This kit starts with our R154 OEM rebuild kit, which has all the major bearings, synchros (3pc for 2nd gear and multi-piece 5th gear) and seals. Next the kit includes all the proven Marlin Crawler upgrades: HD Bearing retainer, Chromoly Thrust Washer, Billet 1-2 Shift Fork, and billet 3-4 Shift Fork.

This kit is for the later model tripod mounted shifter transmissions from the JZZ30 Soarer and JZX100 Chaser with two 3pc synchros. This rebuild kit is NOT for the US MK3 Supra R154. Some later model R154s do have different parts then what we offer in this kit, so please check inside your transmission if it has any 3pc synchros, and verify before ordering. Some additional items may be needed during a transmission rebuild, depending on the condition or your R154 on the inside. We recommend only experienced manual transmission builders do the installation of this kit. Special tools and a bearing press are required, and only a trained eye will catch some issues seen inside an R154. Please use ONLY Redline MT90, MTL, or Royal Purple SynchroMax gear oil!!

We can build your transmission including all the parts in this kit for $1999 plus shipping if you want the work done right by us, with experience from hundreds of R154 builds. Call us if you are interested in having your transmission built for you. Sometimes there are damaged parts above and beyond what is included in this kit, but we will call you once it is inspected and let you know if additional parts need to be replaced.
