See the G Force Crossmember Overview for more info.

When you convert your S10 to accommodate a V8, there are always unforeseen issues that have to be addressed. With a G Force RCS-10-4L80, bolting your transmission to a crossmember and channeling the exhaust off the headers is no longer an issue—just bolt it in and go.

See installation diagram for details.See the G Force Crossmember Overview for more info.

This crossmember is installed with the G Force label facing the rear of the vehicle. However, another determining feature is the crossmember center tube which has a 1/2″ drain slot that is positioned on the bottom and on the passenger side next to the hump weldment.

This crossmember is installed so that the exhaust clearance humps are closed on the top and open on the bottom.

To use the provided 7/16″ hardware it is necessary to enlarge holes in your frame rails with a 1/2″ drill. If you choose to use the stock size 3/8″ hardware, it is strongly recommended to use new Grade #8 fasteners to compensate.

Comes up short

94 Sonoma/s10 with a 5.3 ls 4l80e and I had the same issue as the other review said. Crossmember mounted to the frame perfectly with the necessary hardware. But the trans come up shut an inch short with the engine/trans as far back as possible. More than likely returning and searching for another option

Our Customer Service Crew reached out to you privately. Please let us know if your issue has not been resolved.

Comes up short

For the price, it’s a great crossmember. Big issue I had with it, the trans did not line up with it at all. With the engine all the forward, 6 liter LS and 4L80e, the tail shaft mount came up over an inch short. I had to use an extension from another g-force crossmember I have laying around in order to mount the trans. Beyond that, fit and finish is spot on. Would I recommend the crossmember, hell yeah I would. Just keep in mind, trans may not fit.
