Home Forums Truck Camper Adventure Forum Rancho RS9000 shocks Reply To: Rancho RS9000 shocks


The only shocks I’ve really liked on the front are 4WParts single action shocks. They have worn like iron, giving me just the right dampening with the weight and 3″ lift. Since I have no weight change in front, i don’t need adjustable in front.
The rears are another story. I think I’ve been through 4 sets of Rancho 9K’s in 16 years. Each set were replaced by 4WParts, no questions asked. They just go south after a while. One set rusted out (soda is a killer of sheet metal) after a couple runs over the Mojave Road. I run them on 1 or 0 when the camper is off and right up to 9 (the stiffest valving) when the camper is on. I still think I need 2 sets of shocks on the rear axle, the way I have it set up. A lot of the minute suspension changes are absorbed by the single, thicker overload spring IN the main pack.
I’m thinking double shocks would be good on the rear of Sourdough’s Tiger
Has anyone tried KYB’s? I used these on lighter 4WD’s (up to 6K pounds) back in the day and for a gas shock they were hard to beat. Their claim to fame was the shocks got stiffer when they got hotter, not the other way around as with most shocks. This worked on long rough dirt roads.
