99-06 Silverado/Sierra 1500 rear 4-link pivot boxes. These take the guess work out of designing and fabricating your rear 4-link. Requires cutting the frame rails and sliding the pivot boxes over the end, as well as tying them in to your cage and back half. Works well with our 55" and 60" trailing arms!
These are a weld-it-yourself product.
2" OD cross bar is not included.
