Reviews: Rancho RS9000XL Shocks with 4 Red Shock Boots, Gas Charged - ShockingRS9000XL

These shocks are great!! Can't even tell I'm running my jk with no sway bar

Was looking for an improvement over my Tereflex in how they handled washboard and basic off-road oscillations. Washboards were terrible with the old setup, limping along at 5-10 MPH while being passed by rental sedans. Hate having to air down for a 2 mile FS road. The RS9500s didn't completely solve the washboard issue, but a huge improvement in the oscillations. On-road performance of my JKU Rub is also markedly better. Much more stable ride with less drifting and floating. As for the washboard, one can tell a difference between the firmest and softest setting on the 9500s traveling about 10-15 MPH. But not to the extent I was hoping (although most likely it’s the stiffness of my coil springs). What I settled on was a mid range setting on the 9500s and PSI of about 30 in my 35s. With that 30 MPH on the washboard was comfortable. And off-road is a hoot. Bottom line, well worth the investment.

Put a set on my 2002 Silverado 1500. I've got a poor mans 3" lift on it with the offset torsion key and an add a leaf in the back so the ride was very stiff until I put these shocks on. The ride is much smoother. Had them on for 10 years!!! Hands down the best shock made.

For the rear of my F250 I crank them all the way up as firm as they would go and I don’t carry much load when I’m not trailering and they are better than stock but I didn’t expect just to crank it all the way and leave it there. I thought they could be a little bit more firm. As for the front shocks, I wouldn’t know because they have not been received and I’m not sure when I’ll get them.
