Finally, a true ROCKCRAWLER Transfer case gear set for for the Vitara/Grand Vitara/Tracker. Our gear set is manufactured from SAE 8620 alloy billet material. We believe that welded gears are JUNK! For long wear life and vibration free operation at high speeds nothing else is acceptable. Final reduction of 4.24:1 is a whopping 134% lower than stock! When used with the stock axle ratio of 5.12, it yields a crawl ratio of 79.3 :1! If you look around, the only Vitaras and GV's you find really doing it off road run a CALMINI ROCKCRAWLER! There's a reason! It completely transforms this vehicle's off road capability. Complete kit comes with all new machined billet gears, bearings, seals, 2 quarts of oil and installation instructions for an easy do it yourself at home installation.
