FAQs
What brakes options are available for these systems?
The 4-link rear systems can be used with the OE brakes or converted to disk brakes. There are several configurations of axle bearings and offsets on the rear end. It is the buyers responsibility to verify wheel/tire fitment for proper backspacing and caliper clearance for their wheels of choice
What parts need to be welded during installation?
The 4-link rear suspension requires three welding operations:
1. Welding of the upper crossmember to the frame rails
2. Welding 4 link tabs to the rear end housing (note: this requires 220 V welder and good penetration)
3. Rear sway bar upper bracket to frame rails. Sway bar brackets could be bolted as well.
Does the rear 4-link system work with relocated inboard spring location?
The QA1 rear suspension systems will work with both standard spring and inboard spring mounting locations. The unique lower shock mount design allows for this versatility.
