  • welded or bolt-on

    I received quite a bit of input on my last post and was happy to hear many honest responses about upgraded suspension. Now the only question I have is about some parts being bolted on or welded in. I am talking about the torque arms and sub-frame connectors. Which ones should I do? Bolted on or welded in for both the parts? Thanks!

      Thanks for your advice. I will take your advice as I have found out you are very helpful when it comes to the f-body.

        Just got a set of UMI subframes today. I also vote weld.

          Are you looking at the torque arm (there is only one torque arm) with regard to how it mounts to the chassis in the front? It's held to the rear axle center section by two large bolts, and attachs to a bracket on the tailshaft of the tranny using a bushing (stock configuration), or A) a bracket that welds to the chassis in the front (BMR), or B) a bracket that bolts in place of the g-load brace (Spohn), or C) a "saddle" that bolts into the driveshaft tunnel (Jegster, etc.). Which one are you looking at?

          On the SFC's, weld-in is preferred. Using bolts will sometimes tear the chassis sheet metal where the bolts go through. Bolts can loosen, clamping force is variable. Weld-in suffers from of these problems.

            I am going to weld in the sub-frame connectors when I get them. As for the torque arms I am going to get the bmr ones that replace the stock ones. I am not getting the track pack ones that are much shorter and for cars under eleven second quarters. I am only getting the regular bmr arms for replacement of the weaker factory ones. If that helps. Sorry about mentioning the welding part that was stupid of me.

              No problem... the BMR track pack does take welding. The "stock replacement" is a straight-forward bolt-in replacement.
