Kinda basic, but a good explanation of how beams work...


They mention the steering sitting behind the beams factory... wonder if i can use my factory steering box and mount? Need to find a 2WD F150 to look at. 😁

I found a set of early 80's F150 beams & arms with hubs and rotors for $250, apparently the beams are forged and more desirable. Seems reasonable, but after more reading, factory beam parts aren't strong for really beating on. But I don't know the limitations... if a Bonneville on 35's is too much for stock Ford parts...?

Then, I found this... https://www.diyoffroad.com/i-beam-suspension.html

You can buy the files to fabricate a completely custom beam suspension and have your favorite plasma table owner cut out your parts and DIY them! Looks like you can customize everything from the tabs to the frame crossmembers, beams, arms, swing steering, etc, etc. They even offer upright (knuckle) kits!

I'll have to take some measurements on the Bonneville and see. It would be bitchen to have custom fabbed beams on this car!

I think you would be fine on stock forged beams.

+8 😳 hopefully that’s counting both sides a 4” over beam would be monster on the Pontiac. I personally think stock with a longer radius arm would be plenty.
