Overview

It is constructed for off-road use and is a complete kit.

This spool attaches to your existing gears, ring gear, and axle shafts to deliver full and equal power to both sides. Due to its nature of not allowing tires to spin independently, it is not recommended for street use.
Show original supplier description
The USA Standard Gear ZP FSD60-3-30 is a heavy-duty steel spool engineered to provide maximum traction for demanding applications. Designed for Dana 60 axles with 30 spline shafts and a gear ratio limit of 4.10 & down, this spool ensures both rear tires receive power simultaneously at all times. This direct-drive design eliminates the need for additional components and works with your existing ring gear and axle shafts. This differential spool is intended exclusively for off-road use, such as drag racing, sled pulling, and dedicated off-roading. Due to its nature of preventing independent wheel spin, it is not recommended for street use. The complete kit includes all necessary components for installation, though professional installation is recommended due to the complexity and specialized tools that may be required. USA Standard Gear provides a warranty against defects in materials and workmanship, provided the product is installed and maintained according to instructions and has not been subjected to modification, accident, abnormal use, or misuse. The warranty may be voided if the vehicle is equipped with tires exceeding the manufacturer's maximum recommended size. This warranty excludes incidental or consequential damages, including labor charges, loss of vehicle use, or damage to other vehicle parts.
