C7 Corvette RPM Stage 4 PRO Series WaveTrac Performance Differential Upgrade

The RPM Transmissions Stage 4 PRO Series heavy duty Corvette rear differential assemblies are available for all C7 or C7/Z06 and C7 Grand Sport Corvette applications 2014 - 2019.  RPM Stage 4 series differentials are professionally built with only the highest quality parts to provide improved reliability and performance for street or track use.  With a wide range of available ratios of ring & pinion sets you could replace a factory low ratio ring & pinion gear with a higher ratio gear set that can greatly increase performance.  For some applications such as top speed vehicles you may need to go to a lower ratio set to correctly gear your Corvette for your particular driving needs. As we have limited access to usable cores, you need to send your Diffreential in in advance. All Diffs are built to order and require 2-3 weeks for production. Please plan accordingly.
