Strange Engineering Pro Series Lightweight Steel Spool Ford

The Strange Engineering Pro Series Lightweight Steel Spool is a differential spool for Ford rear ends. It replaces the open or limited-slip differential with a solid, fully locked carrier, so both axle shafts always turn together. Drag racers, drag-and-drive builds, and other high-power applications use spools like this one. It is also known as a rear end spool or locked differential.

Key Features:

• Machined from forged alloy steel for high strength
• Lightened to reduce rotating weight
• Critical dimensions are left oversize before heat treatment
• Heat treated for added strength
• Finish machined after heat treat to bring surfaces within specification
• Designed and machined by Strange Engineering
• Forged in the USA
• Limited lifetime warranty on Lightweight Pro Series steel spools

Strange Engineering builds drivetrain components for drag racing and high-performance use. The Pro Series spool is made for racers who want a strong, lighter-weight locked rear end. A spool is intended for racing and performance use. It is not intended for typical street driving.
