These axles work only with our 8.8 diff conversion.
The level 5 kit comes with 31 spline inners and 32 spline outers and is recommended for drag race or high HP applications. If changing to a spool, use a Strange unit. Spool will need additional machine work to fit. Spool or LSD needs to be compatible with IRS axles.
Customer must use:
07-10 Ford Explorer 8.8 Diff w/ 31 spline spool or LSD (Use Strange Components)
Q45 or Z32 TT rear hubs (32 spline)
