  • Bolt-on installation
    • Included tie plates with extension pieces replace your existing U-bolt plates

This Comfort Ride suspension upgrade system greatly improves your towing experience. It serves as an add-on for your leaf spring suspension, and it provides a notably smoother ride, reducing chucking, axle roll-up, and suspension rebound. This means that you'll experience improved handling, even over potholes and uneven pavement. And the contents of your trailer will stay in place during travel.


Gas Shocks Absorb Road Vibration

While traditional leaf springs support your trailer to prevent bottoming out, they don't necessarily provide a comfortable ride. Due to the rigidity of the steel construction, leaf springs do a poor job of absorbing shock and bounce and limiting sway.


Roadmaster Comfort Ride shocks

Adding these shocks to your existing leaf spring suspension offers a better solution. Gas-powered springs inside of the sealed cylinders compress and extend as you drive. The compression and extension of the springs creates enough force to offset the amount of incoming force or vibration that occurs when you tow over rough or uneven terrain. The result is a more comfortable towing experience.


Comfort Ride Shock Absorbers installed

Many trailers will have shocks mounted at around a 40-degree angle, but this positioning doesn't compensate very well for the up-and-down movement of the trailer's suspension. Roadmaster's patented adjustable frame brackets are specifically designed to allow these shocks to be mounted at an optimum angle between 20 and 40 degrees. As a result, these shocks will have the leverage necessary to limit up-and-down and lateral movement during both compression and rebound.


Rigorous Testing Standards

The Comfort Ride shock absorber system has endured rigorous testing to ensure its durability and longevity. This testing includes computerized Finite Element Analysis, which establishes guidelines to ensure superior product quality and safety. Roadmaster also tested these shock absorbers at the Navistar Proving Grounds, a private test facility that provides real-world handling and safety testing. The result is a safe, long-lasting product that you can trust.


Installation

Installation of the Comfort Ride system is fairly straightforward.


The included tie plates replace your existing U-bolt tie plates. You will need to retain your existing U-bolts and nuts for installation. Once the tie plates are installed, bolt the upper mounting brackets to your trailer's frame with the included hardware. Some drilling is required when mounting the brackets to the frame. Finally, attach the shocks between the tie plates and the frame brackets.

  • Will the Bolt-On Shock Kits for Trailers Work With Underslung Axles
    I do have an option for you but the Lippert Components Bolt-On Shock Kit like part # LC281281 is designed for use on overslung axles (leaf springs over axle) only. Therefore, it should not be used with the underslung (leaf springs under axle) axles that you have. The reason for this is that the shock absorbers would not be long enough and there could be interference with the axle tube. Instead, I recommend using the Roadmaster Comfort Ride Shock Absorbers for Tandem Axle Trailers part...

  • Comparing the Timbren Silent Ride for Tandem Axle Trailers to the Roadmaster Shock Absorbers
    Hey Ryan! Those systems are quite different. The Timbren Silent Ride Suspension for Tandem Axle Trailers w/ 3" Round Axles item # TSR10KT02 is a complete replacement option. It takes away your entire leaf spring set up and requires you to mount your axles directly to it. The installation process in extremely in-depth. You have to remove all of your current suspension components including hangers, you'll need to install a hollow 2" x 4" steel crossmember, and your current axle seats have...

  • Should Pin Box or Suspension be Upgraded to Reduce Jarring and Bouncing While Towing
    A cushioned pin box, like the Trailair Flex Air 5th Wheel Pin Box # LC328492 for a Lippert 1621 replacement that you referenced, will greatly improve the ride between your 2016 Ram 3500 and your Forest River Chaparral 37FL whereas upgraded suspension parts on your trailer are geared more towards the ride quality of your trailer. If the jarring that you are getting is from the trailer bouncing around then I recommend starting with suspension enhancement. From the info you gave it sounds...

  • Replacement Leaf Springs, Wet Bolts, And A Comfort Ride Shock System For A 2016 Keystone Montana
    Hi Jay, There unfortunately isn't a guide to tell us what leaf springs are on your trailer so you'll need to measure the length of your current springs and check the axle for its capacity. To measure you'll need to lift one side of trailer by the frame and let the axles hang. Then you'll measure from the center of one eyelet to the center of the other eyelet. That length along with the axle capacity will tell us what you need. For the wet bolts we'll also need to know the length not...

  • What Is The Best Suspension Upgrade Available For Winnebago 2455BHS Travel Trailer?
    I would be happy to help you find the best suspension upgrades for your Winnebago 2455BHS Travel Trailer. First while we do not carry the blue version of the Road armor 3500-8000lb equalizers you mentioned, the Road Armor # LC696740 are the exact same thing just yellow instead. Both have the same 3500-8000lb rating and the same dimensions.

  • Will Roadmaster Comfort Ride Help Ride Quality of 2026 East to West Ahara 395FB
    Hey Jay, yes the Roadmaster Comfort Ride system part # RM-2470 that you referenced will make a big difference in the ride quality of your 2026 East to West Ahara 395FB. The biggest thing that trailer suspension lacks is dampening which is what shocks provide. The shocks slow the movement of the suspension which makes for a considerable smoother ride quality. If you've ever had a blown shock and noticed how much rougher your vehicle was that's similar.

  • Suspension Enhancement For A Trailer With 8,000 Pound Axles
    Good question, Nick! The Dexter Replacement Dexter Bolt-On Shock Kit # K71-697-00 is designed to fit a 2-3/8" or 3" diameter axle. An 8,000 pound axle will measure 3-1/2", so I cannot recommend going this way. It will be underrated and won't really do what you want it to. I know this is quite a bit more expensive, but the Roadmaster Comfort Ride Shock Absorbers for Tandem Axle Trailers # RM-2470 is specifically designed for an 8,000 pound 3-1/2" axle and would be what I recommend (plus...

  • Recommended Shock Absorber Kit for a 2025 Jayco Pinnacle w/ 3-1/2" Diameter Axles
    Hey Bob, congrats on the new 5th wheel trailer. If your Jayco Pinnacle has 3-1/2" diameter 8,000 lbs axles you can use the Roadmaster Comfort Ride Shock Absorbers for Tandem Axle Trailers item # RM-2470. These shock absorbers are nitrogen-charged so they'll help with the road shock along with trailer bouncing and that chucking feeling. What size are your axles? The plates on these shocks tie into your u-bolts so if you do not have 3-1/2" diameter axles this kit won't work.

    I would be happy to recommend a suspension enhancement option for your 14000lb GVWR 5th wheel trailer.

This option is great for being maintenance free, but will only fit trails with 3-leaf leaf springs,...

  • How to Improve Ride of Trailer With Tandem 8k Axles & MORryde CRE3000 Rubber Equalizers
    We can get you a more comfortable ride, though the Road Armor equalizers truthfully won't do the job as an upgrade over the CRE3000 MORryde Rubber Equalizers like # MR87ZR or # MR27ZR, they would just be replacing one upgraded equalizer with another to little effect. Based on the fact you have these equalizers I'm going to assume you do have tandem, 8,000 lb axles, and the best way to significantly improve your ride is with a shock kit from Roadmaster: - Roadmaster Comfort Ride Shock...

  • Should I Add A Shock Kit To My 2018 Grand Design Reflection 150 Series Camper?
    There really are no drawbacks to adding a shock kit to your 2018 Grand Design Reflection 150 Series 220RK. I do like them as they will smooth out the ride and actually help with sway issues as well. There are a few options to choose from and though they are more expensive, I do prefer the Roadmaster options. These have a Lifetime Warranty and come as tandem axle kits as well. I was unable to find the capacity of the axles on your camper, so I do have all three options listed below. Roadmaster...

  • Suspension Upgrade Recommendation for 2019 Grand Design 351M
    If the suspension of your 2019 Grand Design 351M is currently in good working order but you want to improve what you have by making the ride quality smoother you could go with just the shock portion of the Roadmaster Comfort Ride with part # RM-2470. You'd want to measure the diameter of your axles though. If they are 3-1/2 inch like what most 8k axles fit then the correct kit is the # RM-2470. If they instead are 3 inch you'd want the part # RM-2460.

  • Trailer Suspension Enhancement For a Triple Axle Trailer With 8,000LB Axles And Slipper Springs
    It appears that you have 8,000lb axles on your 2018 Iron Bull triple axle trailer. If this is what you have I recommend the Roadmaster Comfort Ride Shock Absorbers # RM-2470 along with the Add-On Kit for Triple Axle Trailers # RM-2470-50. These shock absorbers will help to reduce shock inside the trailer as well as provide a more stable ride for the trailer. In the event you do not have 8,000lb axles please let me know what weight rating axles you have.

  • Can The Comfort Ride Shock Absorbers # RM-2470 Be Pointed Outwards On a 5TH Wheel With 8K Axles?
    While you could install the Roadmaster Comfort Ride Shock Absorbers # RM-2470 in the other orientation pointed away from the equalizers this would greatly decrease their effectiveness. Since the Equalizer allows for more movement on that side of the axle the shock absorbers have further they can travel to reduce shock. The best options are to either go with the full Roadmaster Comfort Ride Leaf Spring Suspension Kit w/ Shocks # RM-2470-2580 and remove your equalizers. Or you might consider...

    The Roadmaster Comfort Ride Shocks can be purchased separately with part # RM-204000-00. We unfortunately don't sell the mounting hardware separately so you would either have to purchase it directly from Roadmaster or from your local hardware store. I've listed the hardware use to mount the shocks below: 24x M12 flat washer 8x M12 x 1.75 x 100mm bolt - class 8.8 8x M12 x 1.75 nylon insert lock nut - class 8.8 8x 1/2" spacer

  • Can you Use the Roadmaster Comfort Ride Shock Absorbers for 5200 - 7000-lb Axes on an 8000-lb Axle
    The Dexter 8,000-lb axles are typically 3-1/2" in diameter, whereas the Roadmaster Comfort Ride Shock Absorbers, part # RM-2460, only fit on 3" diameter axles (which is standard for 5200 - 7000-lb axles). So, unfortunately, you will need swap these. We have the 8000-lb version of these shock absorbers here. They are part # RM-2470. I've linked to a video review of these for you to look at.

  • Suspension Upgrade For Trailer With 8,000 lb Axles & MORryde LRE Suspension

That means the Trailair won't work with what you have, but there is an option to help with your suspension, which is to add the Roadmaster Comfort Ride Shock Absorbers for Tandem Axle Trailers - 8,000-lb Axles # RM-2470.

    I would be happy to recommend a shock system for your tandem axle trailer. The correct system for your application is going to be based on the rating of your current axles, since each kit is designed to fit a certain diameter axle, and going with a system that is severely overrated will actually hurt the ride of trailer by being too stiff and not allowing the trailers suspension to do its job.
