Revolution Gear & Axle D44-410 4.10 Ratio Ring & Pinion for Dana 44 Rear

Vehicle Fitment

• Fits vehicles equipped with a Dana 44 standard-rotation rear differential - verify axle code, spline count, gear ratio and housing before purchase.

Features

• 4.10 :1 gear ratio tuned for Dana 44 rear axles to restore performance with larger tires or increased load.
• Heat-treated 8620 steel construction for excellent strength and long-term durability.
• Designed for 26-spline standard-rotation Dana 44 differentials to ensure proper fit and gear engagement.
• Precision gear cutting and finish for smoother engagement, quiet operation and reduced wear.
• Improves mechanical advantage, reducing engine/drive-train workload when using high-gear ratios or heavy towing loads.
• Maintains highway drivability when used in appropriate size/tire combinations by optimizing engine RPM.
• Backed by a 2-year limited manufacturer warranty for reliability assurance.
• Installation ready for competent gear installer - requires correct preload, backlash and pattern setup.

Product Description

The Revolution Gear & Axle D44-410 ring and pinion set delivers a robust 4.10:1 gear ratio upgrade for vehicles equipped with a Dana 44 rear differential. If your vehicle has been fitted with oversized tires, added heavy gear, or is used frequently for heavy loads or towing, this gear set helps restore proper mechanical leverage and ensure that engine power is efficiently translated to the axle. Constructed from heat-treated 8620 steel and designed specifically for the Dana 44 platform, it offers a balance of durability, smooth operation, and highway-worthy drivability.

This listing is ideal for off-road ramps, 4x4 trucks or SUVs with Dana 44 rear axles where the stock gear ratio no longer matches the upgraded tire size or load demands. Correct installation is crucial: you must verify the exact axle housing, carrier code, spline count, ring gear bolt pattern, and differential rotation before proceeding. A professional setup is highly recommended to ensure preload, backlash and gear pattern are within specification. Confirm the ring gear bolts and bearing set are sourced simultaneously unless included.
