Bumpy pavement and washboard roads can make any haul feel rough. This kit uses heavy-duty gas shocks that take on the worst of the vibration and road shock so your ride feels steady and calm. With hydraulic oil inside for damping and nitrogen gas to stop foaming, every bounce is controlled. It’s built for 5,200-lb to 7,000-lb (3") overslung axles with shocks that extend to 13-1/2" and compress to 8-5/8", giving you consistent performance under load.
When the road gets uneven, the combination of oil and pressurized gas inside each shock keeps the trailer planted. The oil handles the core damping to smooth out vertical movement, while the gas charge keeps performance steady even after long stretches. That balance helps reduce sway and body roll so bumps and dips don’t toss your cargo around.
Hardware takes a beating under a trailer, which is why each component in this kit is finished with enamel for long-term rust resistance. Rain, grime, or road salt won’t eat away at the brackets or shocks. It’s a setup that lasts through miles of towing in all conditions.
There’s no guesswork here. The included tie plates, U-bolts, and self-tapping screws replace your old hardware for a simple bolt-on installation. The upper brackets mount directly to the frame, and with at least 4" of clearance between the inside of the tire and I-beam flange, everything lines up like it should. Once in place, the shocks sit at up to a 45-degree angle to dampen axle movement efficiently.
For rigs with axles mounted below the leaf springs, this kit delivers a clear improvement in ride quality. Whether it’s a long highway stretch or uneven ground near camp, the Lippert Bolt-On Shock Kit steadies your suspension so each trip feels smoother and more controlled from start to finish.

Year later, I made my own shock setup using a very common gas shock. The setup is much simple than the Lippert and allows the shock to set better angle to be more efficient. If you are thinking about adding shocks to your trailer look at all the options, do your homework. I have made a second set and will be replacing the Lippert set on the rear axle.

Not too well, Bad clearance problems between the shocks and the tires. If trailer is straight and upright tires have clearance between the shocks. The tire sidewalls rub the shocks after making turns especially when backing up. Turned the shocks upside down to help alleviate the clearance problem and it helped some but does still rub the sidewall to an extent. So as not to end up buying more tires I have removed the shocks. Clearance is down to 14 inch to 12 inch.

The Lippert Components Bolt-On Shock Kit is not a trailer specific item. It will fit many different trailer styles, but the existing structure of a given trailer may require modifications like you experienced. The product installation guidelines are linked on the product page, Id recommend taking a look at them and then examining the trailer frame where the shocks would install to make sure everything is compatible.

Unable to install the shocks based upon the instructions provided and I’ve not seen any other instructions. These WILL NOT fit the smaller frame used by the Grand Design 2018 2150. In fact, I have not found anyone who carries a size for smaller frames. Sad too. I really, really could have used them with the frost heaves we passed over in Alaska.

Love the shocks that e-trailer has. We have them on now for about a year. They were easy to install and provide an amazing ride.

Glad we had what you needed, William! And holy cow! A broken undercarriage?! That's a pretty serious issue. Was the set up too heavy or too light originally?
