OK, technically not an R154, what I actually have is a brand new r150. For those that don't know this is just as strong as an r154 but with shorter ratios: R150: First Gear: 3.830:1 Second Gear: 2.062:1 Third Gear: 1.436:1 Fourth Gear: 1.00:1 Fifth Gear: 0.838:1 R154: First Gear: 3.250:1 Second Gear: 1.955:1 Third Gear: 1.310:1 Fourth Gear: 1.00:1 Fifth Gear: 0.753:1 As you can see this is brand new, never been on a car before. After doing some research if you want to make your R150 or r154 even stronger then marlin crawler do a billet bearing carrier Heavy Duty Bearing Cover Plate, R-series | Marlin Crawler, Inc. and an upgraded thrust washer Chromoly R-series Thrust Washer Kit | Marlin Crawler, Inc. to massively increase the life of your box. Comes with a front prop section, all the release bearing, slave cylinder setup etc and not pictured but a bell housing and input shaft extension to bolt straight up to a Toyota 1UZ v8. (No gearstick) this is the short input shaft version. ***DEPOSIT TAKEN***
