Description
Quality Construction. Crafted from high-quality steel, Revolution Gear & Axle constructs their ring and pinion gears for superior strength and longevity. Each component is precision-machined to exacting tolerances, ensuring a perfect fit and smooth operation. The gears undergo a heat-treating process that increases their hardness and resistance to wear, making them exceptionally durable under extreme conditions.
Installation. Installing the Revolution Gear & Axle GM 14 Bolt 9.50 Inch Ring & Pinion Gear Kit with a 4.56 ratio requires professional expertise. The installation process typically involves disassembling the differential, careful setup of the new ring and pinion gears to ensure proper backlash and tooth contact, and reassembly.
