You’ve found Marlin Crawler’s one-of-a-kind “Total Spline” 23-spline 2.28:1 transfer case input gear, the strongest 23-spline input gear in the world, now available in our Ultimate Strength Competition-grade Material!

This will convert a 21-spline 1979-1995 4-cylinder transfer case to a 23-spline version so that the stronger 5spd R150F (3.0L V6) and R151F (2.4L Turbo I4) transmissions may be used. Fits any gear driven t/case originally fitted to 4cyl 1979-1995 trucks and 4Runners. Commonly used in crawl boxes for a number of later model applications. Factory 2.28:1 Gear Ratio.

This is the strongest 2.28:1 input gear in the world.

• Total-Spline™ Technology

• Heat Treated Chromoly Steel

• Full-length Spline Engagement

• Addresses one of the weakest parts of your t/case

• Minimizes Dual Case Coupler wear, combats strip-outs

You will not find a stronger input gear!

Build your transfer case right the first time, and put your tools away!
