13th Annual Maintenance May Is Here!

Welcome to our 13th annual Maintenance May Sales Event — and this year we’re doing something a bit different:

We’re putting the spotlight on Differentials — one of the most important and most overlooked parts of your rig.

Now through May 31, get 10% back on:
• Differential Re-gears
• Rebuilt Third Members
• New Bearings & Seals
• Lockers, ARB Compressors
• …and more!

Why Marlin Crawler? Because We Build Differentials the Right Way — Since the 1970s.

Our founder Marlin pioneered a proprietary gear setup method that delivers a superior mesh pattern with reduced heat, noise, and wear. Today, we still build every third member the Marlin Way — and we’ve been at it longer than anyone else in the industry.

✅ Built with Premium Hardware
✅ Gear Choice: Revolution (Premium) or Yukon (Trail & Competition Proven)
✅ Trusted by Thousands — Proven on the Trail, Quiet on the Street

When you install a Marlin Crawler diff, you’re not getting someone else’s idea of quality. You’re getting the original — built by the team that defined the standard.
