Unlock the full potential of your drivetrain with the 4th Gen Pickup 5.29 Gear from Revolution Gear and Axle. If you’ve upgraded to larger tires, then re-gearing is essential—and this package delivers. Designed specifically for 1986–1989 Toyota 4-cylinder pickups and 1984–1989 4Runner models, this gear kit provides the perfect balance between power and efficiency. Whether you’re hitting the trails or hauling heavy loads, this 5.29 gear ratio ensures your truck responds confidently.

Since factory gears can’t keep up with oversized tires, you’ll likely notice reduced torque and sluggish performance. Fortunately, this gear package solves that problem. By optimizing power delivery, it improves acceleration, climbing, and throttle response. Additionally, the package helps maintain proper RPMs on highways, which boosts fuel efficiency over time. As a result, your truck performs better in every situation.
