Nerd Rods

TriFive, Stage 2 - Fully Welded Frame

       Nerd Rods Stage 2 TFC4 is the fully welded version of our popular DIY frame for the 1955-1957 Chevy Passenger cars. The TFC4 frame is designed to bolt up to the car’s stock body mounts and accept the C4 1984-1996 Corvette Suspension with no required body modifications. The complete package lowers the car and giving you an engineered suspension solution instead of the normal pile of band aids that most cars end up with as they buy a kit to fix this and a kit to fix that. With the Stage 2 frame you’ll just source your own suspension and assemble it at your own pace.

TFC4 Stage 2 - FAQ

Q: Are motor mounts included?

A: No. The Motor mounts attach to the front cradle from the corvette you get with your suspension. You will need to FAB up a motor mount or see below for one of our motor mount kits.

Q: Is the transmission mount includded?

A: Yes, the transmission mount will slide forward and backward to allow for almost every transmission combination possible.


Q: Do I have to use coil over shocks?

A: Yes, springs control the car and shocks control the springs. The stock springs allow you to do neither of these adjustments and with all the possible combinations of bodies, motors, transmission and driving styles the coil over shocks lets us compensate for all of these with ease and so we design our frames to utilize them.

Q: What suspension fits this frame?

A: Suspension from the 1984 - 1996 Corvettes, commonly called C4 Corvettes, and will bolt onto this frame. You can also swap in a Live Axle rear end without live axle kit option if you want more width.

Q: Will you ship a frame to me?

A: Unfortunately, we don’t ship stage 2 frames. The crating is far too complex, and we’ve had incidents with almost everyone shipped. Local pickup or private carrier will need to be arranged to get your Stage 2 frame from our shop to your location.
