Besides being the best looking brace out there, it's also the most rigid. we use a 1.25" chrome moly tube which is welded to a box on each end. All welds are tig welds for maximum durability.
These boxes use all four bolts on the tower to mount the brace solidly (no heim joints to pivot and let your engine compartment turn into a parallelogram). One look at one of these braces and you will see the design, fit, welds, and finish are second to none.
