Built the Marlin Way – Since the 1970s
We don’t follow manuals. We follow Marlin. Our proprietary gear setup method — developed in the 1970s and handed down only to our master builders — is unlike anything else in the industry. Buying from us promises a more precise gear mesh pattern, resulting in a quieter, stronger, and longer-lasting differential. Proven on the trail and trusted for daily driving by tens of thousands of Toyota/Lexus owners, weekend wheelers, and professional race teams — including top of class and podium finishes at King of the Hammers, Baja 1000, World Extreme Rock Crawling Championship Series, and three consecutive Formula Toyota national titles.
✅ Industry-leading reliability record over a vast install base
✅ Built in-house by technicians who’ve been with us since the early 2000s
✅ Proven to outlast traditional setup methods
This is more than a build — it’s the original, still done the right way.
