Features to know about
Smoother Ride and Less Bounce: Heavy-Duty Nitrogen-Charged Shocks
Rough roads can make a trailer buck and sway. This add-on kit brings two heavy-duty, nitrogen-charged shock absorbers that take the punch out of bumps and washboard stretches. Each shock measures 17-1/2" extended and 11-1/2" compressed, giving plenty of travel to control motion on a triple-axle setup. The result is reduced bouncing and “porpoising” so the trailer rides steadier and your gear stays put inside.
Built to Work with 3" Round Axles: Direct Fit for 5,200-lb to 7,000-lb Axles
No need to hunt for extra brackets or spacers—this kit is made for 3" diameter round axles, the common size in 5,200-lb to 7,000-lb ranges. The included tie plates with extension pieces replace your existing U-bolt plates so the shocks mount right where they belong. The upper brackets attach cleanly to the trailer frame with the supplied hardware for a solid, factory-style fit.
Easy Upgrade for Triple-Axle Comfort Ride Systems: Adapts the RM-2460 Kit
Already running a Roadmaster Comfort Ride setup on a tandem-axle trailer? This kit extends that same proven system to a triple-axle configuration. It bolts on to the existing RM-2460 hardware, adding the third pair of shocks needed to complete the upgrade. Adjustable mounting brackets make it simple to position the shocks vertically and avoid space conflicts around the frame or belly pan.
Steadier Tracking on Any Road: Built-In Sway Control
When a trailer starts to shift side to side, towing becomes tiring. The Comfort Ride Add-On Kit helps keep things in line by damping lateral movement through its angled shock geometry. The shocks absorb the energy that would otherwise twist the frame or push against the hitch, giving a more controlled, predictable tow whether the road is smooth pavement or patchy gravel.
Durable Hardware That Lasts: Bolt-On Steel Components with 1-Year Warranty
All brackets and tie plates are steel with a sturdy bolt-on design for long-term reliability. The kit includes every piece of mounting hardware you need to get the job done without guesswork. Backed by a 1-year warranty, it’s a dependable way to strengthen your suspension and keep your triple-axle trailer tracking true mile after mile.

Video Transcript for An In-Depth Look at the Roadmaster Comfort Ride Add-On Kit for Triple Axle Trailers
Hi, everybody, Andy here with etrailer.com. Let's take a look at this Roadmaster Comfort Ride Add-on Kit for triple-axle trailers. This add-on shock kit is going to adapt your Roadmaster Comfort Ride system for use with a triple-axle trailer with leaf spring suspensions. And this is going to fit your three inch diameter, 5,200 pound to 7,000 pound axles. And on your screen, I am including the model number of that Comfort Ride system that this kit is going to work with. And as you can see, these shocks are banded at the install height, so this is how you are going to receive them.
And this is a bolt-on installation, which includes everything that you're going to need to install this. It includes the tie plates with extension pieces that will replace your existing U-bolt plates. The upper brackets mount on your trailer frame with the included hardware, and the shocks attach to the tie plate extensions and to the upper brackets to help dampen movement of your axle. The extended length of these shocks when they're fully extended is gonna be 17 1/2 inches from eye to eye. And then when they're fully compressed, it's going to be 11 1/2 inches.
Instructions are included to guide you through the installation process. And this does have a limited lifetime warranty from Roadmaster. (metal clanking) Well, that's gonna wrap up our brief look today. I do hope that it was helpful for you. Again, my name is Andy.
Thank you for joining me.

Prior to installing this kit, the tires would contact the wood floor of the 5th wheel (Cougar 25RES) and were starting to wear a groove. Now that the kit has been installed the rubbing has stopped. I've also noticed the drawers, that had previously self-opened, are now staying shut. Installation was fairly straight forward. I drilled and tapped the holes, for the plates, as the self-tapping screws refused to go in straight. I also put a nut on the outside screws, the others are blocked by the belly pan.

Installation Review (will update after road test) Great tutorial video. Highly recommend a quality bolt/nut loosening solution. Makes a big difference. Rented an angle drill for the top bracket 5/16th" holes due to low clearance (I ended up buying one it was so useful). Job went smoothly. I wouldn't cut your underbelly until after the install. I may not cut mine at all. Top of shock pushes against it but that shouldn't cause a problem. I added a number of photos, to include the solvent and jack. Top notch company with high quality merchandise.

What I like better than the products are the people and support received
from EVERYONE I have talked to at etrailer. If Forest River was half this good, I might buy another one, but most of the questions or problems I have come across with our fifth wheel have been solved by someone here after talking to a generic moron at the manufacturer.

Installed two of theses on a Tracer 23RBS, 28Ft. Had everything needed for complete install, decent quality. Instructions had just enough info for proper install. Gas shocks a plus, anticipating a more stable ride.

My axles are attached above the leaf springs. This complicated the installation a bit but was not prohibitive. I have tandem axles and purchased two(2) of these kits for the trailer. Immediately, we noticed that the trailer was more stable when parked without the outriggers deployed. I wish I could get detailed drawing of the shock brackets. Knowing the designed angle where the shock absorbers mount would have been very helpful with the installation.
I am leaving for my first road trip and look forward to the increased stability during towing and not having the trailer contents thrown about during transport.

There are differences between the Roadmaster Comfort Ride Kits # RM-2460-2580-3 # RM69NQ and # RM-2460-2570-3 and I have them listed below. They all include the Comfort Ride Shock Absorbers for Tandem Axle Trailers - 5,200-lb to 7,000-lb Axle # RM-2460 and Comfort Ride Add-On Kit for Triple Axle Trailers - 5,200-lb to 7,000-lb Axles # RM-2460-50, but the leaf springs between them are all different. # RM-2460-2580-3 Roadmaster Comfort Ride Slipper...
view full answer... - What is Warranty of Roadmaster Comfort Ride Triple Axle Add On KitHey Dave, sorry for the confusion on that. I checked with Roadmaster and the Roadmaster Comfort Ride Add-On Kit for Triple Axle Trailers # RM-2460-50 that you referenced does have a limited lifetime warranty. I sent an update to have this information corrected on the product page.

Two of the Roadmaster Comfort Ride Add-On Kit item # RM-2460-50 are going to include every single shock, bracket, nut, bolt, and washers included with the Roadmaster Comfort Ride Shock Absorbers for Tandem Axle Trailers item # RM-2460. The Roadmaster item # RM-2460-50 shocks are exactly what you need for your 3" round, underslung, 7,000 lbs axles. They're really going to smooth out your ride and absorb...
view full answer... - Roadmaster Comfort Ride Add-On Kit For A 2025 Coachman Apex Nano 190RBSHi Sid! It sounds like you are looking for the Roadmaster Comfort Ride Add-On Kit for Triple Axle Trailers - 3" Axles # RM-2460-50. That said, this is intended for 5,200-lb to 7,000-lb axles as that is where 3" diameter axles are typically found. Are you absolutely sure your axle does not measure 2-3/8? That is kind of the standard diameter for a 3,500 pound axle and the Roadmaster Comfort Ride Add-On Kit for Triple Axle Trailers - 3,500-lb 2-3/8" Axles # RM-2450-50 is designed with that...
view full answer... - Shock Kit Recommendation for 2022 Coleman Dutchmen Lantern 17BThe best shock kit for your 2022 Coleman Dutchmen Lantern 17B that has 3 inch underslung axles is the Roadmaster Comfort Ride kit part # RM-2460-50. This will make a huge difference in the smoothness of your trailer's ride.
view full answer... - Will the Roadmaster Comfort Ride Add-On Kit Work On Underslung Axles?
Yes, there are single axle shock kits for underslung axles. These are typically used to add on shocks for the extra axle on triple axle trailers but they also work on single axle applications. These shocks will work on overslung and underslung axles. If you have a 2-3/8" diameter 3,500 lbs axle you will want the Roadmaster Comfort Ride Add-On Kit item # RM-2450-50. If you have a 3" diameter 5,200 lbs to 7,000 lbs axle you will need the Roadmaster Comfort Ride Add-On Kit item # RM-2460-50.

The # RM-2460-50 you were looking at is a single add on kit for a triple axle trailer, and isn't what you would use on your tandem axle trailer. This kit will do a fantastic job of improving the ride and towing quality of your trailer as the nitrogen filled...

- Shock Absorber Kit That Will Work on Single Axle Trailer With 3 Inch Diameter AxleWe do have a shock kit that will work for your 2022 Jayco Jay Flight with a 3" diameter single axle; it is technically called an add-on kit for Roadmaster's Comfort Ride shocks but can be used for a single axle trailer, which Roadmaster has verified for us. The correct part is the following: - Roadmaster Comfort Ride Add-On Kit # RM-2460-50 The # RM-2460-50 says it is for 5,200 lb to 7,000 lb axles, but it is really for 3" diameter axles - it's just that the most common 3" diameter axles...
view full answer... - Recommended Bolt-On Shock Mount Kit For A 2022 Jayco Jay Flight SLX 7 195RBThe correct kit will depend on the weight capacity and diameter of your axle, but we definitely have a couple options for you to look at. From what I could find about your 2022 Jayco Jay Flight SLX 7 195RB, the GVWR will be 3,995 pounds, so I definitely recommend double checking the axle capacity before going with one of these. With that out of the way, first we have the Lippert Bolt-On Shock Kit w/ Heavy Duty Gas Shocks # LC281255 for a 3,500 pound 2-3/8" axle or # LC281281 for a 5,200...
view full answer... - Recommended Suspension Enhancement for 2017 Grand Design Momentum 376th Toy HaulerI have a solution for your 2017 Grand Design Momentum 376th, but there is a not a SuperSprings or Sumo Springs product designed for this application. The best solution to improve the handling and reduce chucking and porpoising on your trailer is the Roadmaster Comfort Ride Shock Absorbers for Tandem Axle Trailers - 5,200-lb to 7,000-lb Axle # RM-2460 and Roadmaster Comfort Ride Add-On Kit for Triple Axle Trailers - 5,200-lb to 7,000-lb Axles # RM-2460-50. This heavy duty shock system with...
view full answer... - Are New U-Bolts Needed When Installing New Suspension On An RVWhen installing a new suspension system like the Roadmaster Comfort Ride Shock Absorbers for Tandem Axle Trailers # RM-2460 you mention, it is not required but a good idea to replace your old U-Bolts. Reason being that, any bolt, of any grade, when torqued, stretches. The better the grade the less it stretches, and I'm assuming manufacturers aren't using the top grade. That being said, when you look at how the suspension system is designed, there is 4 U-Bolts holding the axle, to the springs,...
view full answer... - Comparing Roadmaster Comfort Ride Shock Absorbers for Triple Axle Trailers to Tandem and Add-On KitYou are correct that they are the same thing. The Roadmaster Comfort Ride Shock Absorbers for Tandem Axle Trailers # RM-2460 combined with the Roadmaster Comfort Ride Add-On Kit # RM-2460-50 will have the same parts as the Roadmaster Comfort Ride Shock Absorbers for Triple Axle Trailers # RM-2460-3. So there is no difference aside from that fact that one is for tandem axles with the add-on kit to upgrade for triple axles and the other comes with everything in one kit for a triple axle trailer.
view full answer... - Are Shocks Still Needed When Adding a Shock Absorbing Equalizer to a Triple Axle 5TH Wheel Trailer?As your 2005 Keystone Raptor 3212DS is a triple axle you will need a kit like the MORryde Rubber Equalizers for Triple Axle Trailers # MR39ZR. The Lippert Road Armor # LC696740 will only fit on tandem axle trailers. I do recommend also installing the Wet Bolt Kit # MR86ZR with the equalizers. This will allow the suspension to move more freely. While the equalizers and wet bolts above will allow the suspension to absorb some road shock, adding shocks will still improve the overall ride...
view full answer... - Recommended Shock Absorbers For Trailer With Single 3" Diameter AxleI have another option for you but the Roadmaster Comfort Ride Add-On Kit for Triple Axle Trailers - 5,200-lb to 7,000-lb Axles # RM-2460-50 is an add-on for a tandem axle kit to add shocks to a triple axle trailer and will not work on a single axle trailer. Since there is not a Roadmaster Comfort Ride option for a single axle trailer I recommend the Lippert Bolt-On Shock Kit w/ Heavy Duty Gas Shocks - 5,200-lb to 7,000-lb (3") Axle # LC281281 which will fit your 3" axle perfectly.

The Roadmaster Comfort Ride Shock Absorbers for Tandem Axle Trailers - 8,000-lb Axle item # RM-2470 fits 3-1/2" axles. The Roadmaster Comfort Ride Add-On Kit for Triple Axle Trailers - 5,200-lb to 7,000-lb Axles item # RM-2460-50 fits 3" axles. You will need to determine what size axles you have to decide which kit to buy. I have linked a review video so you can see this system in action.
view full answer... - Shock Kit for Forest River Vengeance 5th WheelIf your 2016 Forest River Vengeance has tandem 2-3/8-inch axles you can use Roadmaster Comfort Ride Shock Absorber kit # RM-2450 which has nitrogen shocks to reduce the bounce from your leaf spring suspension. If it is a triple axle you will also use the Add-On Kit # RM-2450-50. If instead you have tandem 3-inch axles you can use kit # RM-2460 and add part # RM-2460-50 for a triple axle setup. Lippert kit # LC281281 is for single axle trailers.
view full answer... - Should 2019 Cyclone 4005 with Triple Axles be Fully Loaded when Installing Comfort Ride Shock KitWhat you want to do is load your trailer about halfway so that your suspension will be sitting in the middle of fully loaded and dry for installing the Roadmaster Comfort Ride Shock Absorbers # RM-2460. I confirmed this with my contact at Roadmaster. Please note that since you have a triple axle trailer you also need the Add-On Kit # RM-2460-50. Attached is a review video and the written installation instructions for you to check out.
view full answer... - Will the Roadmaster Comfort Ride Add-On Kit Work On Underslung AxlesYes, the Roadmaster Comfort Ride Add-On Kits like part # RM-2460-50 for 5,200 lb - 7,000 lb axles will work on both overslung and underslung axles without issue.
view full answer... - Can Coil Over Shocks Be Used With The Roadmaster Comfort Ride To Add Lift To Suspension? If you are trying to gain some lift you will want to use a Lift Kit # RR23QX or if your trailer is experiencing sag due to weight adding a couple sets of the SumoSprings Trailer Helper Springs # SS26MV will help to support the weight and reduce sag. The Roadmaster Comfort Ride # RM-2460-50 was designed with the resistance of the shocks in mind and not an additional spring so they are not going to be strong enough for a type of coil over shock.
view full answer... - Timbren Suspension Versus Shock Absorbers for Triple Axle TrailerAll around, shock absorbers like the # LC281255 would provide a smoother ride than a rubber spring like the Timbren SES type system like # TTRA1032. You'll want to be sure to use the correctly rated system for your axle capacity. The # LC281255 you'd looked at is rated for 3500 lb axles, you'd need three of them. For a higher rated 5200-7000 lb axle, use # RM-2460 along with the # 2460-50 add-on.
view full answer... - Best Fit Bolt-On Shock Kit for a 2019 Palomino Puma 5th Wheel TrailerFor your 2019 Palomino Puma 5th Wheel Trailer, I recommend you use the Roadmaster Comfort Ride Shock Kit part # RM-2460-50 instead of the Lippert Components Bolt-On Shock Kit part # LC281281. The reason for this is because the Roadmaster Kit is designed to be mounted on the inside and to the bottom of the frame rail. Therefore, you won't have to worry about the minimal frame to tire clearance that you have now. Unfortunately, I cannot advise on notching the frame, using wheel spacers,...
view full answer... - Can I Use the Roadmaster Comfort Ride Add-On Kit for Triple Axle Trailers on a Single Axle Trailer?I spoke with my rep at Roadmaster and he said as long as you have a 3" axle then the Roadmaster Comfort Ride Add-On Kit for Triple Axle Trailers item # RM-2460-50 will fit your 22’ Apex Nano trailer as a single axle application. The upper brackets will mount on the trailer frame with included hardware and you will replace your existing u-bolts with tie plate extensions that the shocks will attach to.
view full answer... - Shock Kit for Triple Axle 2019 Mesa Ridge with 4,400 lb AxlesSince Lippert 4,400 lb axles are the same diameter as 5,200 lb axles (3 inches) and you have a triple axle setup on your 2019 Mesa Ridge the kit you would want is the Roadmaster Comfort Ride part # RM-2460 with the add-on # RM-2460-50 which comes with everything needed to add shocks to all three of your axles and will make a huge difference in ride quality.

Very well. We just drove the Alcan and the stretch of road from the Alaska border to Destruction Bay can best be described as an RV demolition course, due to melting permafrost. The suspension performed well, with no issues. Many an RV have substantial damage on this section, especially trailers, as most have under-engineered suspensions. The shocks, most likely, have saved me some grief.
