Revolution Gear & Axle GM 10-Bolt 8.5in/8.6in 4.88 Ratio Face Hobbed Ring & Pinion Set

This Revolution Gear & Axle kit includes a face hobbed ring and pinion gear set designed for GM 10-bolt 8.5-inch and 8.6-inch rear axles. The 4.88 gear ratio is a popular choice for those looking to improve acceleration or accommodate larger tires on their vehicle. Face hobbing is an advanced gear cutting process that creates a stronger, more durable tooth profile compared to traditional methods, which can lead to a longer lifespan for your drivetrain components.

Choosing the right gear ratio is crucial for how your vehicle performs. A 4.88 ratio will make your engine work less at highway speeds if you've installed larger tires, or it will significantly improve your off-the-line acceleration and towing capability if you're running stock or slightly larger tires. This set is well-built with precision machining to ensure it fits right and performs reliably. Proper installation by a qualified technician is recommended to achieve optimal performance and longevity from these gears.
