Why Rough Country N3 Shocks Work So Well on GMT800 Trucks

The factory shocks on GMT800 trucks were never designed for leveling kits or increased suspension travel. N3 shocks are.

N3 technology highlights:

  • 10-stage variable valving

  • Nitrogen gas-charged design

  • Faster rebound control

  • Improved damping across rough terrain and pavement

Translation: less bounce, more control—especially with bigger tires.

Ride Quality & Performance Benefits

With the N3 fronts installed, you’ll notice:

  • Reduced front-end bounce

  • Improved steering response

  • Better control over potholes and washboard roads

  • Increased stability with larger wheels/tires

  • More confidence on-road and off-road

Firm when needed. Compliant when cruising. Exactly what a half-ton truck should feel like.

Rough Country’s Performance Shocks

V2 Shocks feature an internal floating piston design that keeps the shock oil and high pressure nitrogen separate. The result is a lightning fast reaction with no cavitation just unbridled vibration damping at each and every obstacle. Features a T6061 brushed aluminum body with black anodized accents which dissipates heat faster than other materials. The 46mm piston offers countless years of durability. The V2 is designed to be mounted body-up for a more interesting look on the vehicle.

  • 46mm High Flow Piston
  • T6061 Brushed Aluminum Body
  • Mounts Inverted

Safety & Suspension Health

Worn or under-valved front shocks reduce braking stability and steering control—especially dangerous on lifted trucks. Fresh N3 shocks restore predictable handling and reduce stress on suspension components.

This is safety maintenance with bonus performance.

    Have had these things in a few days now in my 1500 Silverado with a leveling kit. I have 10 plys so the ride has always been rough with the cheap name brand shocks I had before. After a summer of off-roading I broke one of those cheapies right in half. I ordered these shocks for an amazing price as a pair! Surprisingly enough they were here within a couple days. I threw them in the same night. Right away I noticed the shock looked much beefier and the shaft part of the shock was a lot bigger than a stock shock. I noticed right away they ride much smoother than my other ones and they seem to stay stiffer when you need it and light driving they are soft. Loving them so far!

    So far much better ride quality than blown out factory shocks, install was quick and easy.Ignore the description it will fit on a 4wd avalanche. Rough country’s website confirmed via the part number and they are currently on my z71 avalanche.

    Seem to be ok on the front of my 2000 silverado base model 4×4. Don’t forget to order boots if you want them covered up. They come just like in the picture

    I put these shocks on a leveled 02 Silverado extended cab. The piston rod and body are thicker than what I previously had on it. I was running monotubes. These are twin tube. They have a fast rebound on bumps. But they are a little softer than I was hoping for. That being said they seem to be great shocks for town, highway and for dirt roads with washboards. They do allow a little bit more body roll because they are softer shock. But it makes for a smoother ride on choppy roads and washboards. I would recommend over OE replacements.

    Rough country is reliable a good purchase. However, the first photo shows front shocks and the third shows rear shocks. The top with the bolt on and the bottom being a fork is front. Both sides being a bushing to put a bolt through is rear. I received a rear needing front shocks as I was putting my level kit on. Of course I didn’t open the box till I have my front end torn apart.

    With the price being under 100 dollars I expected to get maybe a year out of them, one of those you get what you pay for. I put them on my 2000 Silverado with a 2 inch lift/level and they were great for about three days. Now they ride horrible and my truck bounces all over the road, I would spend the extra money and buy something else highly do not recommend getting these was a waste of money as I’m now looking for new shocks

  10. Only the motors are good

    Missing hardware
    Of all things, I was missing the top nut for one side. A quick trip to my auto parts store and I had it resolved. It’s a 3/8” fine thread, the stock struts are a coarse thread…I will say they ride MUCH better than my stockers!
