Why TDP’s snap ring is better than the original GM part

General 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 load
• Slightly smaller inner diameter for a tighter, more secure fit in the groove — eliminating the slipping issue that plagued the factory design
• Larger outer diameter for increased contact area and even greater holding strength

Fitment — important notes

• 1997–2003 C5 Corvette — uses 1 snap ring per differential
• 2004 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
