QA1 Crossmember Question

If your current K member is in good condition you can seam weld and reinforce the steering box mount and LCA pivot tubes.

The QA1 tubular K member isn’t any stiffer than a reinforced stock K, and it’s only about 8-10 lbs lighter. The only real advantage is a bit more room for a larger oil pan.

The tubular LCA’s are similar, they’re really not a huge advantage over boxed factory LCA’s. The old design allowed for about an extra 1” of suspension travel, which was great for lowered cars. The current design has a bump stop design that pretty much eliminates that and makes the travel the same as factory. They could be modified pretty easily but it would take modifications.
