Locking Differentials Give Your Toyota 4Runner Maximum Traction

A 2nd gen 4Runner locking differential is one of the most impactful upgrades you can make for off-road capability. A locker forces both wheels on an axle to turn at the same speed, eliminating the problem of power going to a spinning wheel with no grip.

Our assembled units include the Grizzly Locker, a mechanical automatic locker that operates on 30 spline axles and engages under power with no switches or air lines needed.

Ring and Pinion Gears Let You Match Your Axle Ratio to Your Tire Size

When you run larger tires, the factory gear ratio becomes too tall and causes sluggish acceleration and extra drivetrain strain. Regearing corrects that mismatch and restores the performance feel the truck had before the tire upgrade. The gear ratios available include:

  • 4.11 suits mild lifts with moderately sized tires and keeps highway driving comfortable while improving on the factory setup.
  • 4.56 works well for mid-size tires and moderate overland builds, making it one of the most popular all-around ratio choices.
  • 4.88 is built for larger tires and builds that spend most of their time off pavement where crawl performance takes priority.
  • 5.29 is for the most aggressive setups with oversized tires, high lifts, or added weight from armor and recovery gear.

 

Choosing the right ratio depends on your tire diameter, engine output, and how you use the rig. Picking the correct ratio restores throttle response, reduces heat in the drivetrain, and makes the truck feel like it was built for those tires from day one.

Install Kits and Bundle Packages Cover Everything You Need

A gear installation done without proper bearings, shims, and seals often has to be redone. Our install kits and bundle packages for the 2nd gen 4Runner differential are organized to match the way real builders plan their builds. The categories available include:

  • Assembled Differentials arrive ready to drop in with no extra setup, saving hours of labor compared to building from loose components.
  • Gears are available as standalone ring and pinion sets in multiple ratios for builders who prefer to handle their own installation.
  • Install Kits include all the bearings, shims, and seals needed to complete a proper gear swap the first time without shortcuts.
  • Bundle Packages combine gears, install hardware, and locker options into one purchase, which is ideal for regearing both axles at once.

 

Ordering everything together means fewer shipping delays and a faster path from purchase to install. Bundle packages are the smartest way to plan a full drivetrain overhaul without missing a single component.
