What is a mini spool and how does it work?

A mini spool replaces the spider gears inside your open differential carrier. By doing this, it locks the two axle shafts together, ensuring that both rear wheels receive 100% of the engine's power at all times. This provides maximum traction, especially off-road or during hard acceleration.

Is this mini spool suitable for street driving?

No, this mini spool is not recommended for street-driven vehicles. Because it locks both wheels together constantly, it can cause tire scrubbing and binding when turning on pavement, leading to increased tire wear and potential drivetrain stress.

What vehicles does this Yukon mini spool fit?

This mini spool is specifically designed for Ford 8.8-inch rear axles with 31-spline axles. It fits a broad range of Ford and Lincoln models, including many Broncos, Crown Victorias, F-150s, and Mustangs from the late 1970s through the early 2010s.

Product Details

If you're looking to get the most traction out of your Ford 8.8-inch rear end, a mini spool is a solid option. This Yukon Gear mini spool replaces the spider gears in your open differential carrier, forcing 100% of the engine's power to both rear wheels simultaneously. It's a straightforward way to achieve full-time locked traction, which is ideal for off-road use, drag racing, or any situation where maximum grip is the priority.

Yukon performance spools are made from high-quality materials designed for strength and longevity in demanding applications. This particular mini spool is built to fit Ford 8.8-inch rear ends that use 31-spline axles. It installs directly into a standard open carrier case, making it a more economical choice than a full locker for achieving full-time lockup. Keep in mind that this setup is not recommended for daily street-driven vehicles due to the constant binding that can occur during turns.

This mini spool fits a wide range of Ford and Lincoln vehicles, including popular models like the Ford Bronco, F-150, and Mustang, as well as the Lincoln Mark LT. If you're building a dedicated off-road rig or a drag car, this Yukon mini spool offers a cost-effective path to serious traction.
