We never stop building at Marlin Crawler. That's why we've put together this great Differential Builder Package to feed the builder in you!
This Spool Locker Builder Package is for 1979-95 8-inch 4-cylinder applications. For 1986-87 22R-TE Turbo applications, please use the 6-cylinder version of this package.
Includes the following High Quality Products:
- (1) Marlin Crawler Ninja Gears
- (1) Marlin Crawler Ninja Setup Kit with Japanese Bearings
- (1) Yukon Spool Locker
- (1) Oversized 29-spline Triple Drilled Pinion Flange
Once installed, we suggest following our differential break in procedure to maximize the life of your new investment. Also, keep in mind that there will be debris generated from the break-in period, so you may want to run cheap mineral oil for the first 500 miles and then replace that out with this high quality Redline oil.
