Ring & Pinion Dana 44 Ad vanTEK Rear 5.38 Rubicon

The Ring & Pinion Dana 44 AdvantEK Rear 5.38 Rubicon is a high-performance differential gearset engineered for heavy-duty off-road recovery, rock crawling, and extreme terrain navigation. This Dana 44 ring and pinion kit delivers the low-end torque multiplication needed to extract vehicles from deep mud, rocky inclines, and challenging backcountry conditions where standard gearing falls short.

The 5.38 gear ratio provides aggressive torque amplification—critical for slow-speed power delivery during technical climbs and load recovery. This ratio is paired with a 28-spline pinion shaft, engineered to handle the shock loads and sustained torque demands of extreme wheeling. The Dana 44 platform is the industry standard for heavy-duty rear axle applications, trusted for its strength and reliability in the most punishing terrain. The AdvantEK gearset specifically combines manufacturing precision with materials science to minimize gear noise and maximize component longevity under repeated high-stress cycles.

This gearset is designed for serious 4x4 operators—Jeep Rubicon owners, expedition builders, and recovery specialists who demand dependable axle performance in extreme conditions. The 5.38 ratio transforms driveline response in low-range applications, making it ideal for vehicles equipped with modern tire packages (35-inch and larger) where factory gearing becomes inadequate for controlled descent and load management. Installation requires professional rebuild service with proper bearing preload and backlash adjustment to ensure peak performance and durability.
