A bolt-in Adjustable Transmission Mounting Solution for Your Second Generation C10 Pickup

While the engine swap seems to get all the love and focus of our project dollars, you can’t forget about what’s going to bolt up to that new engine and sit in the tunnel next to you. Even if you’re going to keep the stock transmission, many times an LS swap or adjustable engine mounts create enough setback that your stock transmission crossmember won’t work anymore. Even more to consider is when you drop the coin for that beefy six-speed manual or fancy electronic overdrive automatic to bolt up to your engine swap. Then you really need to start sharpening your pencil to determine correct driveline angle and how to support the transmission properly.

Gone are the days of spending hours cutting up a stock crossmember, massaging it with a grinder and a welder to make some crude affair to get you close. Forget all that and simply use our ingenious bolt-in steel C10 transmission crossmember for 67-72 C10 pickups! We’ve designed this C10 crossmember to be universal transmission crossmember in nature to support most any manual or automatic transmission yet be a complete stress free bolt-in solution that will have your transmission properly supported and secured at the correct driveline angle in no time.

Mount Just About Any Transmission You Can Think of With Our Bolt-in Crossmember

Our 67-72 C10 transmission crossmember is built in-house using 10 gauge steel that is laser cut and fully welded for strength and powder coated black for great, long lasting looks. The included frame boxing plates bolt to existing frame holes on your C10, so there is no grinding/slotting/drilling involved in installing them. The boxing plates can be inverted to provide a 1/2-inch in mounting height offset to get the perfect driveline angle. Slots in the boxing plates also allow for front-to-rear adjustment of the 67-72 C10 transmission crossmember as well to line up with your transmission’s tailshaft mounting pad/trans mount. This provides a bolt-in mounting solution for nearly any transmission application you can think of.

Premium 3/8-24 mounting hardware is included to install the crossmember with locknuts and washers to ensure your final mounting location stays where you put it. Our fabricated C10 dual exhaust crossmember provides generous room for the routing of up to 3-inch exhaust tubing tucked up nice and close for your exhaust installation to provide plenty of exhale ability for your C10 pickup’s engine no matter how low your C10 sits.
