Full Spool

The USA Standard full spool is engineered for maximum traction, ensuring 100% power is delivered to both rear wheels simultaneously. Constructed from 8620 steel and heat-treated for durability, this spool integrates with your existing gears by connecting to the ring gear and axle shafts. It provides equal power distribution to both sides without requiring additional components or engagement mechanisms. It is important to note that due to the spool's nature of preventing independent tire rotation, it is not recommended for street-driven vehicles. Installation by a professional shop is recommended due to the complexity and specialized tools often required for differential work, although a DIY installation is possible for those with the necessary expertise and equipment. USA Standard Gear provides a limited warranty covering 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. This warranty excludes implied warranties of merchantability or fitness for a particular purpose and does not cover incidental or consequential damages.
