****Update Over time, JYB shock absorbers have never loosened, so the car's comfortable driving feels like you are discharging. You feel every little crack in the road. So a big truck doesn't feel like a car anymore. Heavy duty was too much. Removed and back in stock on 11/08/2015 Monroe shock absorbers. The *****KYB Mono Shock made my Jeep feel like a new truck with 415,000 miles and still going. 4th set of shock absorbers, but look at the mileage. The Rancho shocks were the worst I've tried…
