Serpentine Belt W/ exhaust brake

Geno's has the right belt from Cummins for the 5.6L with a Jacobs exhuast brake. Yes you can order them from a cummins dealer but the price is a little higher plus shipping to them and then to you. I always get my belt from Geno's when I need one.

Power steering pump works smoother after replacing belt. Had 127,000 miles on old one.
