Product Details
RS5000X Gas Shock, The core of this new and innovative shock from Rancho is the unique and patented rebound valving system and an advanced compression phase of the shock absorber. This proprietary process developed by the ride engineers at Rancho will elevate the overall handling and performance of your vehicle on and off-road. Each RS5000X shock is gas pressurized to 150 PSI.* The twin tube, gas pressurized shock has a variety of advantages including minimizing air-to-oil mixture that can cause foaming and shock fade. Gas pressurization also provides a mild boost of spring rate to the vehicle. The RS5000X series features a 2-1/4-inch diameter shock body. A larger shock body allows for increased fluid capacity to operate cooler and to increase vehicle control and performance at varying speeds and terrains. The RS5000X series combines a larger shock body with all-weather fluid, allowing the shock to withstand internal temperatures between -40 and 248 degrees Fahrenheit. The Rancho RS5000X series design includes patented progressive rebound and compression discs. At lower speeds or in the earlier stages of the shock's travel, an eccentric disc in the valve shim stacks will engage the valving at lower frequencies, helping to control the energy of motion as the cycle of the shock increases or decreases in its action. When hitting a pothole, off-road trail obstacle or similar activity, Rancho's Progressive Engagement Valving allows for early flow of fluid, helping to reduce harsh initial impacts and to control the flow of fluid in a progressive, gradual manner through the valving. During on- or off-road driving activities like washboarding or when travelling a rough fire road, the early flow of fluid helps to minimize a "rough" ride as the piston movement is able to glide through the initial travel motion of the shock with minimal ground impact or force. If needed, the Progressive Engagement Valving will further engage to maintain control and stability.

Awesome Ride
Love these Rancho Shocks on my 4x4 suburban. The adjustable setting is a really nice feature. I put them on lower stock setting around town and beef them up when carry a load to around 5 or 7. The adjustable setting actually works and is very nice. I just got back from a hunting trip in Colorado and the shocks were amazing on 4x4 only trails in the mountains.

Better Than Factory
I put Rancho shocks and struts on my 2007 Chevy Suburban replacing the original suspension. The Rancho's not only smoothed out the ride and improved handling, but they lifted the front 2" to level the vehicle out. Installation was easy (if you know what your doing). Highly recommended. Service and prices from Shock Surplus was world class.

Great Shock for Any Condition
I put these on my '10 Taco. They have a real sweet spot for all driving conditions I've encountered so far. I put them at 5 for highway, 3 for country rough roads and city roads, 1 for super rutted or washboard stuff. When I tow, I'll probably start at 7 and see how that goes.

The Expert's Opinion
"Rancho's offering covers the most diverse application list out of all the brands here at Shock Surplus, giving a ton of options for drivers looking for economical performance. Our favorites are the monotube RS7MT for the best comfort, or the RS9000XL for vehicles that need daily comfort and weekend performance."

INFORMATION
Questions? We've got answers
Rancho shocks are typically tuned to deliver a firmer, more controlled ride than stock, especially on trucks and SUVs that carry extra weight or see off-road use. On pavement, you’ll usually notice improved stability with less body roll and better control over bumps, though the ride can feel a bit stiffer compared to softer factory shocks.
Off-road and under load is where Rancho really shines. They’re designed to handle rough terrain, towing, and added weight with confidence, keeping the vehicle more composed over uneven surfaces and repeated hits. Adjustable models, like the RS9000XL, let you fine-tune the firmness, so you can soften things up for daily driving or stiffen them for hauling and trails.
Overall, Rancho shocks are a great fit if you want a durable, more heavy-duty ride feel with the ability to handle tougher conditions, even if that comes with a slightly firmer on-road experience.
Some Rancho shocks are adjustable, but not all models include this feature. Entry-level options like the RS5000X are non-adjustable, with fixed valving designed for a consistent, out-of-the-box ride.
However, Rancho is best known for their RS9000XL series, which features a manual adjustment knob with 9 levels of firmness. This allows you to easily dial the shocks softer for daily driving or stiffer for towing, hauling, or off-road use.
In short, Rancho offers both fixed and adjustable options but if you’re looking for tunability, the RS9000XL line is where Rancho really stands out.
Click the 'Select Your Vehicle' button above the 'Add to Cart' button to make sure the shocks fit your exact vehicle. If needed, the site will send you to the right shocks for your ride. If your vehicle has been lifted, use the dropdown menu to pick the correct lift height. For example, if you have a Rough Country 6-inch lift kit, choose Front 4–6" and Rear 3–4" (the rear is usually smaller than the front). Still not sure? Our sales team is happy to help.
Rancho shocks typically last around 40,000–50,000 miles under normal driving conditions, which is in line with most non-rebuildable shock absorbers. For trucks that spend most of their time on pavement, they can last longer, while frequent off-road use, towing, or rough terrain can shorten their lifespan.
Like any shock, performance tends to fade gradually over time. If you start to notice increased bouncing, reduced control, or a harsher ride, it’s usually a sign the shocks are wearing out and ready for replacement.
Overall, Rancho shocks are built to be a durable, long-lasting option, and many models are backed by a limited lifetime warranty—giving you added confidence for long-term use.
