Strange 31 Spline Spool
Eliminate your factory differential for a more consistent performance at the track with this 1986-2014 Mustang Strange 31 spline spool! This spool replaces your factory differential with an 8.80lb 31 spline spool. This saves a significant amount of weight while increasing strength due to the simplistic design. Both axles will turn at the same speed with an equal amount of uninterrupted force, making it a great choice for drag racing. This allows the use of larger axles that can handle greater amounts of torque!
Fitment Note
Spools are meant for drag race use only! Do not use on street driven Mustangs!
