Attention all 12-1/4" NV4500 and Getrag users.
All 12v trucks will need the center bore machined out.
All flywheels must be checked, we have seen some 24v trucks that have had the 12v flywheel.
1988 - 1993 12 Valve Cummins fitted with Getrag 5 Speed Transmission.
We no longer offer replacement Getrag clutches.
The 12 1/4" NV4500 clutch will fit your stock Getrag flywheel or you can upgrade to the 13" conversion kit found here. 5 speed 13" upgrade.
