GRC400 is 100% Polydimethylsiloxane fluid. This silicone is recommended in place of putty in front diff's of today's electric touring cars and other vehicles, through testing we feel like the performance and especially the consistency of this ultra thick silicone is a better solution than a spool or the commonly used putty method for front diff's. This package includes a modified syringe for easier filling of differentials while limiting pesky air bubbles, and a GRC decal/chassis labeling sheet.
