RPM Transmissions

RPM TRANSMISSIONS SALES DEPARTMENT WILL BE CLOSED 6-8-2026 thru 6-12-2026.

The production guys will still be working on current orders. If you need to place and order or get an update on an order you have in with us make sure you give us a call this week.

C7 we had in the shop earlier this week for a torque tube rebuild. What’s crazy is he drove the car to us from an hour away!

Our phone system has been down for most of the day. Sorry for any inconveniences, we are working to get this resolved as soon as possible.

Spring time is just around the corner. Make sure you schedule your Corvette in for your yearly torque tube nest maintenance.

Today we had a very rare occasion at RPM. We have the last 4 generations of Corvettes in house. 2 C5 Z06s in for work, our shop C5 Z06, A rowdy 680rwhp 2000 mile C6 Z06, an insanely low mile C7 ZR1 Manual and a C8 Z06. Its awesome to see them all together under one roof.

Just in case anyone missed the memo it is red C5 Z06 day at RPM apparently 🤣

We have mild to wild combinations here.
The far left is a mild street combo in for a trans and torque tube rebuild.
In the middle is a fairly aggressive road race/time attack combo.
Then on the end is our shop C5Z racecar which runs 4.30s in the 1/8 mile with a 588ci big block chevy using one of our rear mounted TH400s and IRS 9 inch.

The RPM boys ! We will be closed staring now until January 5th! Hope everyone has a safe and Merry Christmas!

RPM will be closed Thursday and Friday and will be back open on Monday. Hope everyone has a great Thanksgiving!

This is without a doubt the baddest C6 Corvette differential on the planet! Fresh off the build bench and ready to ship to the customer. The RPM Transmissions Stage X ZR1 3.42 Differential. This unit is assembled with 100% brand new components. No core parts are used in this build. The Stage X features all of our Stage 4 upgrades, those upgrades include a Wavetrac Differentials torque biasing limited slip differential, Driveshaft Shop 300M billet steel stub axles, RPM Transmissions billet aluminum pinion support and Performance Metal micro polished Motive Gear 3.42 ring and pinion gears. Our Stage X package adds the incredibly robust ZR1 differential case, which has considerably more reinforcement webbing and is cast from a much stronger alloy than even the Z06 differential case, our own in-house CNC machined 6061 billet aluminum right and left side covers along with our billet rear differential cover. This unit is also fitted with our trans/differential brace kit. This differential build has been punished in every form of racing at over 2000rwhp. It has ran 6s in the 1/4 mile in multiple different race cars and withstood over 250mph blasts in 1/2 mile, mile and land speed combinations. If you need the absolute baddest unit on the planet, give us a call and get your Stage X build rolling!

William Hogan out this weekend getting a win in his bad ass turbo OBS truck! Will is rowing his own gears with one of our custom built T56 Magnum units using a G-Force Transmissions faceplate billet gearset! Keep an eye on this guy. Hes getting this combo dialed in for some drag and drive events in 2026.
