C5 C6 Corvette Differential Snap Ring (Inner)Direct replacement for the discontinued GM part 12458084Made in the USA!Retains the stub shaft onto the differential side gearSold individuallyWhy TDP’s snap ring is better than the original GM partGeneral Motors discontinued the original Corvette differential snap ring — GM part number 12458084 — leaving Corvette owners and rebuild shops scrambling to find a reliable replacement. Here at Texas Drivetrain Performance, we engineered and manufacture our own version right here in the USA, and we didn’t just replicate the factory part — we improved it in every meaningful way:10% thicker steel than the original GM part, significantly increasing resistance to bending, cracking, and slipping under loadSlightly smaller inner diameter for a tighter, more secure fit in the groove — eliminating the slipping issue that plagued the factory designLarger outer diameter for increased contact area and even greater holding strengthFitment — important notes1997–2003 C5 Corvette — uses 1 snap ring per differential2004 C5 Corvette — may use 1 or 2 snap rings depending on build (order 2 to be certain)2005–2013 C6 Corvette — requires 2 snap rings per differential
