We are excited to release our 80- & 100-series Transfer Case Part Time Spool Kit! Made in Japan exclusively for Marlin Crawler, our Spool Locker replaces the factory transfer case differential carrier assembly permanently locking the rear output to our spool itself.
Our Japanese manufactured Marlin Crawler spool replaces the factory transfer case differential and deletes the viscous coupling. This spool is an excellent complement to our 3.12:1 Crawler Gears and allows you to convert from Full-time 4WD, or All-Wheel Drive, or Selectable 4WD High Range. Additional parts are needed included an OEM Switch and Locking Hubs to complete the conversion. The use of locking hubs allows for a better steering feel, less wear on front axle parts (important with inner axle shaft upgrades), and increase fuel mileage.
More tech information coming soon!
