Revolution Gear & Axle D30S-456TJ 4.56 Ratio Ring & Pinion for Dana 30 Short Pin

Vehicle Fitment

• Fits vehicles equipped with a Dana 30 short-pinion front axle housing (standard rotation) - verify axle code, spline count and rotation before ordering.

Features

• 4.56 :1 gear ratio designed for Dana 30 short-pinion front axles.
• Constructed of heat-treated 8620 steel for high durability and strength.
• Short-pinion design improves fitment in front-axle configurations where clearance is tight.
• Precision-machined ring and pinion gearset for smooth engagement and reduced gear noise.
• Enhances torque delivery when oversized tyres or added load make stock gearing inadequate.
• Maintains highway drivability when matched properly with tyres and gear ratio selection.
• Backed by a 2-year limited manufacturer warranty for reliability assurance.
• Requires correct professional installation - preload, backlash and gear pattern must be properly set for optimal performance.

Product Description

The Revolution Gear & Axle D30S-456TJ ring & pinion set offers a 4.56:1 gear ratio upgrade specifically for Dana 30 short-pinion front axle configurations. Built from highgrade 8620 steel and precision machined for smooth engagement and quiet operation, this gearset is designed to regain traction and driveline performance when larger tyres, added loads or off-road demands exceed the capabilities of factory gearing.

Ideal for off-road-capable vehicles with Dana 30 front axles (especially those upgraded with oversized tyres or extra weight), this gear set provides improved torque delivery and better match for modified driveline conditions. Because this is an axle-specific part rather than a simple vehicle-specific plug-in, correct fitment verification is critical: confirm the exact axle housing code, pinion spline count, rotation type, and ring-gear bolt pattern before installation. Professional installation, including correct preload, backlash and gear pattern setup, is strongly recommended. Ring gear bolts, bearings and seals must be sourced separately unless specifically included in the kit.
