Revolution Gear & Axle GM 14-Bolt 10.5in Rear Axle 4.88 Ratio Thick Ring & Pinion Set

If you're looking to re-gear your GM 14-bolt 10.5-inch rear axle for larger tires or heavier towing, this thick ring and pinion set from Revolution Gear & Axle is a solid option. A 4.88 ratio is a popular choice for trucks running 37-inch to 40-inch tires, helping to bring your engine's RPMs back into an efficient range for better acceleration and fuel economy. This set is specifically designed as a 'thick' gear set, which means it uses a stronger, thicker ring gear that requires a special installation kit, but offers improved durability for demanding applications.

Revolution Gear & Axle is known for well-built drivetrain components. This ring and pinion set is made from strong steel and precision-cut to ensure smooth power transfer. The 'thick' design is a notable upgrade over standard gear sets, providing more tooth contact area on the ring gear, which can handle more torque and reduce the risk of tooth breakage, especially important when you're pushing your vehicle off-road or under heavy load. Proper installation by a qualified technician is crucial for this type of gear set, as it requires specific setup and backlash adjustments.
