Thread: 48 Chevy 1/2 ton

Tweet

I have built over 30 streetrods & have used many IFS. I was one of the first to install a Must II IFS back in the 70's before kits were available.
There have been failures of the Must II because it is hard to duplicate the original installation of the strut rod. The new strutless lower A arms are not as strong as the factory units( in my humble opinion). The load is distribuated over a small area. This view comes from one w/a background in mech engr.
The GM clip has a very wide stance & the lower control arm distribues the load over a large area. One can see the difference if the two units are side by side.
I currently am building my 3rd 48 Chevy trk & it was a no brainer to install a 84 Buick Regal IFS.

Ps if i were to buy a Must II IFS kit I would not chose Fat Man's.
