Customer Reviews
I replaced the front two KO2s on my Ram 3500 dually diesel truck with KO3s. The KO2s only had 13k miles on them when I replaced them due to them being uneven, shiming, and they we're making alot of noise. I'm hoping these do not do the same! The rears have 18k and are wearing evenly and are still quiet. I do haul a truck camper weighing approx 5k on nearly all of these miles.
Store was awesome that we quit In-N-Out even did an alignment a very satisfied with the work they done
Beefy tires, no problems.
