Revolution Gear & Axle 05-23 Toyota Tacoma 8.0in IFS Reverse 4.56 Ratio Thin Ring & Pinion Set

This 4.56 ratio ring and pinion set from Revolution Gear & Axle is built for the 8.0-inch Independent Front Suspension (IFS) found in 2005 through 2023 Toyota Tacoma models. Opting for a different gear ratio, like this 4.56, is a common upgrade when you've changed tire size or are looking to improve your vehicle's performance off-road or when towing. A lower numerical ratio (like 4.56 compared to the stock 3.73 or 4.10) means the gears turn more times for each rotation of the driveshaft, which helps bring your engine RPMs back into their optimal range, especially with larger tires.

Revolution Gear & Axle uses heat-treated 8620 steel for the ring and pinion gears, a well-known material for its strength and durability in drivetrain components. This set is specifically designed as a 'thin' gear set, meaning it uses a thinner pinion gear. This design choice is often made to allow for better clearance within the differential housing, making installation smoother. The reverse cut means the teeth mesh in the opposite direction of a standard cut gear, which is necessary for the reverse rotation of the front differential in many IFS setups.

When installing a new ring and pinion set, proper setup is crucial for longevity. This includes checking backlash, pattern, and preload. It's recommended to follow the manufacturer's installation instructions carefully and to break in the new gears according to their guidelines to ensure they last for many miles to come.
