C5 Side Cover O-Ring 97-05 Corvette Differential

C5 Side Cover O-Ring 97-05 Corvette Differential — Exclusive TDP Product

If you’re servicing the rear differential on your 1997–2004 C5 or 2005 C6 Corvette, replacing the differential side cover o-ring is not a step to skip. When this o-ring degrades, differential fluid will seep from the side cover — and left unaddressed, fluid loss accelerates wear and leads to costly differential damage over time.

Discontinued by GM — TDP is your exclusive source

General Motors discontinued this o-ring, leaving C5 Corvette owners and rebuild shops without a reliable OEM source. Rather than leaving the community without options, Texas Drivetrain Performance stepped up to exclusively source this precise, application-specific replacement. It seals exactly like the original — no improvising with ill-fitting generic o-rings, no second-guessing the fitment.

Fitment note

This o-ring fits both the driver and passenger side covers on the C5 and 2005 C6 Corvette.

Best practice: Always replace all o-rings and seals any time the differential is opened for service — regardless of how the old ones look.
