I went from original-ish power steering box on a 68 c10 to this. Holly Molly what a difference. Swapped to hydro boost w/ new steering pump and added a cooler. My god what a difference. Tracks straight no jogging the wheel to stay in lane. 1.5 turns either way from straight to lock. 3 total lock to lock instead of the stock 72 turns lock to lock. So worth it. Stop procrastinating and get it.
