Doetsch Tech shocks write-up from Rocky-Road.
http://www.rocky-road.com/jeepsus.htmlWe ran Rancho 9000s shocks for many years. While we managed to look past the rough ride, even on the softest setting, we tired of the constant problems.... the knobs would break off, the adjustment would seize up, they rusted quickly, and the air system never worked right. Not to mention that due to serious usage we'd break one or two Rancho shocks every year... VERY expensive to replace! So we threw away all our RS9000s. We've also dropped the other shock lines and switched over to the Doetsch Tech shocks.
These shocks are absolutely perfect for folks who want a great on and off-road shock, but don't want to spend over $200 buying them (and doesn't want to deal with their hassles). These shocks are valved lightly for a very smooth highway ride. Forget those hard riding knock-the-fillings-out-of-your-head shocks (Rancho5000, ProComp, Trailmaster, Rough Country, etc.). All the other big name shocks were designed for pickup trucks and will ride stiff on mid-weight Jeeps. We chose the DT shocks specifically for their ability to provide great on and off road performance for Jeeps. We size them perfectly to run with all our lifts and carry them in most every length for any application.
