This forged chromoly upgrade kit is the solution. Why upgrade? Under hard launches and high-torque applications, the factory C5 and C6 Corvette differential output shafts can twist and break — with the longer driver side shaft being especially susceptible. Both shafts in this kit are machined from a modified chromoly alloy that is significantly stronger and more resistant to torsional stress than the factory parts, giving you the confidence to launch hard without breaking a shaft. Included in kit (1) Driver side forged chromoly shaft (1) Passenger side forged chromoly shaft (2) heavy-duty inner snap rings Upgraded inner snap rings Every kit ships with upgraded inner differential snap rings already included. These snap rings are significantly thicker and stronger — an upgrade in its own right that adds an additional layer of reliability to your drivetrain build.

Installing this HD shaft requires replacing the factory combined unit with a separate C6-style differential side gear. Some 2004 C5s already came with the 2-piece design — verify your configuration before ordering.

An 85mm socket is an uncommon metric size that most tool suppliers simply don't carry — and the ones that do charge a significant premium. Our TDP-manufactured socket solves that problem at a fraction of the cost. What makes the TDP 85mm socket different Most large metric sockets share four problems that make them less than ideal for this application. They are unnecessarily deep — our socket is extremely shallow by design, maximizing torque transfer and making installation and removal quick and efficient. Most large sockets have tapered inner walls, introducing excessive clearance between the socket and nut. This allows the socket to rock under load, rounding the nut edges over time. Our socket has straight inner walls with no taper — a precise, flush fit that protects the nut and transfers torque cleanly. Most sockets in this size range require a 3/4" or 1" drive. Ours uses the standard 1/2" drive, compatible with virtually every torque wrench already in your shop. Pricing: Third-party 85mm sockets typically run $300–$500. Our TDP socket is $200 — the most economical option available without compromising precision or quality.

We have accumulated a large quantity of these countershafts and will be liquidating them as a one-time deal — all used take-offs in excellent condition — and are offering them at a price that reflects that. Once this stock is gone, it's gone for good. While an aftermarket replacement for this countershaft does exist and is a quality option, there is simply no substitute for the original Tremec OE part. The OE countershaft was manufactured to Tremec's own exacting specifications and represents the gold standard for this application. If you have the opportunity to install an original Tremec countershaft in your rebuild, this is it — and at liquidation pricing, there's no reason not to. When would you need to replace the cluster gear? The cluster gear is not a routine wear item. It typically needs replacement when the gear teeth have been damaged — most commonly the result of overheating or a hard breakage event. When the teeth are damaged, smooth gear engagement is no longer possible and replacement is the only fix.

GM has discontinued this part (old GM part number 12456211). Fitment & Important Notes Interchanges with GM part number 12456211 1997–1999 C5 Corvette (automatic only) This bushing must be removed and replaced any time the torque tube bearings are replaced. The bushing is pressed in and covers a bolt that retains the rear torque tube transmission shaft — the bolt cannot be accessed until the bushing is removed. Because of the way it is pressed in, removal requires cutting into the side and using a chisel and hammer to knock it loose. This process destroys the bushing, making replacement mandatory. 2000 C5 Corvette (automatic only) This was a split production year. Some 2000 automatic Corvettes require bushing removal for a bearing replacement and some do not. We recommend disassembling the torque tube before ordering to confirm exactly what your specific unit requires. 2001–2013 C5/C6 Corvette (automatic/manual) This bushing is present but does not need to be removed in order to perform a bearing replacement. Replacement is only necessary if the bushing itself is worn or damaged. 2014–2019 C7 Corvette (automatic/manual) This bushing is used in the rear and/or front of the C7 torque tube. The C7 arrangement differs from the C5/C6 — if the coupler bushings become damaged on a C7, they will cause these insulator bushings to fail as well, meaning replacement is needed more frequently than on C5/C6 models.

The C6 Corvette differential tends to self-destruct when making serious horsepower/torque While the C6 Z06 differential swap is a great solution, they're discontinued and nearly impossible to find plus very expensive! C7 Diff Compared to C6 Z06/ZR1 8.75" ring gear - same size as the C6 Z06/ZR1 Main housing has a much stronger with more bracing built into the casting Side covers are approximately double the thickness (this is the main weak point of the C6 Z06/ZR1) Conclusion: The C7 diff conversion is an excellent (and the only feasible) option!

The problem with the factory pinion spacer The factory GM pinion spacer is a solid-style, one-size component with zero adjustability. The pinion typically remains loose after torquing the nut, forcing repeated disassembly, modification and reassembly to chase the correct preload. Getting it wrong has real consequences — incorrect preload causes inconsistent gear tooth alignment, leading to premature gear wear and eventual gear failure. The TDP solution Our exclusive billet steel Corvette adjustable pinion spacer eliminates the guesswork entirely. The two-piece design — upper spacer, lower spacer, and shim pack installed between the two halves — allows the builder to select the exact combination of shims needed to hit the correct preload spec on the first attempt. No repeated disassembly, no frustration, no compromises. Machined from billet steel for maximum strength and dimensional stability, this spacer handles the demands of both street and high-performance applications without compression or deformation over time.
