The Gen-Y Hitch Shock Absorbing 5th Wheel to Gooseneck Pin Box - Auto Latch - Lippert 1621/1621 HD - 25K Item # GY66FR is designed to replace Lippert 1116, 1621, 1621 HD, 1716, Fabex 665, and M&M 665 5th-wheel pin boxes. As long as your pin box on your 2017 Grand Design Momentum 399th matches one of the above then it is compatible. view full answer...
The Rhinobox was definitely an unpopular choice for manufacturers to go with so swapping it out with the MORryde Cushioned 5th Wheel Pin Box for 18K to 21K Trailers w/ Lippert Rhino # MR55QR would definitely give you a major improvement in ride quality.
That being said, a 2022 Grand Design Momentum 351MS has a GVWR of 16,800lbs so you would want to use the MORryde Cushioned 5th Wheel Pin Box for 14K to 18K Trailers w/ Lippert Rhino # MR83QR instead. The internal spring for this pin box... view full answer...
While we do have an option for you to get a smoother, more comfortable ride for your 2017 Grand Design Momentum 399TH, the Center Point # LC1565401 is going to raise your trailer by 2 inches, and there isn't any alternative method of install or anything that won't affect your ride height. So instead, what I recommend are shock absorbers from Roadmaster:
- Roadmaster Comfort Ride Shock Absorbers for Triple Axle Trailers # RM-2460-3
These are the right size for your triple-axle '17 399TH,... view full answer...
The length I'm seeing for a 2021 Grand design Momentum 395MS Fifth Wheel Toy Hauler is 43' 8" so the only compatible cover available for you is the Classic Accessories PermaPRO Deluxe Extra Tall 5th Wheel Cover or Toy Hauler Cover # CA80-299-203101-RT.
This cover fits fifth wheels 41'- 44' in length and has adjustable front and rear tension panels and elasticized hem corners to provide a snug fit. The zippered panels allow access to the RV doors and storage compartments for easy access... view full answer...
The information I found says that your 2022 Grand Design Momentum 395MS 5th Wheel Toy Hauler has a 1621HD pin box. That would make the Trailair Flex Air 5th Wheel Pin Box # LC369535 the correct pin box for you.
A Portable Air Compressor # BDW41002 is good to keep with the 5th wheel so that you can make adjustments to the air bag when needed so the pin box rides at the correct height. view full answer...
It looks like a 2021 Grand Design Momentum 5th Wheel Toy Hauler could have come with either 7,000 lb or 8,000 lb axles. I have attached the correct bearing kits and braking assemblies for each of these options below.
7,000 Lb Axle:
Dexter Electric Trailer Brake Kit part # 23-464-465
Axle Bearing Kit part # BK3-210 (2.125" Seal)
Axle Bearing Kit part # BK3-200 (2.250" Seal)
8,000 Lb Axle:
Dexter Electric Trailer Brake Kit part # 23-434-435
Inner Bearing part # 25580

Yes, the Trailair Flex Air 5th Wheel Pin Box part # LC369535 will replace the Lippert 1621 Pin Box on your Grand Design Momentum 381M. The Trailair Flex Air will provide a dramatic improvement in overall ride quality as well as reducing the amount of wear and tear on both the vehicle and trailer. view full answer...
So the issue isn't going to be the shackle strap length as getting straps that are less than an inch longer won't make up the difference you are seeing. The issue is that the Road Armor Shock Absorbing Equalizer Kit # LC696740 you have is the wrong size to replace the equalizers on your 2018 Grand Design Momentum 350M. I was able to check with Grand Design and find the equalizers that fit your rig, which are the Equa-Flex:
- Equa-Flex Cushioned Equalizers # LC279688

It sounds to me like you possibly had some non-ISR rails in your bed and that were only compatible with that 16k Husky hitch that the previous owner had. You're going to want to first confirm that your hitch will fit ISR (Industry Standard Rails) and then swap out your base rails to safely tow your trailer and end any doubt about safety.
If your hitch is compatible with ISR rails then I recommend the B&W Custom Installation Kit w/ Base Rails for 5th Wheel Trailer Hitches # BWRVK2500.... view full answer...
You'd have to measure the pilot diameter of the wheels on your Grand Design as the Lionshead Center Cap part # 275-000004-005 fits pilot diameters that are 4.88 inch to 4.9 inch. view full answer...
We definitely have all the parts you will need to convert your your 2020 Grand Design Momentum 349M 5th Wheel toy hauler to disc brakes. There isn't one complete kit but I have listed all of the parts you will need below.
Kodiak Disc Brake Kit - 13" Hub/Rotor - 8 on 6-1/2 Lug Pattern item # K2HR712. You will need one per axle.
Hydrastar Electric-Hydraulic Actuator w/ Line Kit for Disc Brakes item # CAR-HBA16-2. You will just need one. The actuator kit comes with all the needed brake lines... view full answer...
The formula you used is only a guess and wouldn't be an accurate way to determine your trailer's actual pin weight since it's a triple axle toy hauler. The only way to get an accurate number would be to measure at highway weigh station. You'll hook up to the trailer and drive onto the scale with only the 4 wheels of the truck sitting on the scale. You can then unhook from the trailer and measure the weight of the truck. You'll subtract the truck's weight from the weight while connected... view full answer...
The TorkLift GlowStep Revolution Scissor Steps w/ Landing Gear - 4 Steps - 27-1/2" Base - 375 lbs # TLA8004 are a fit for your 2018 Grand Design Momentum 328M. They can be used to replace your current steps if desired. If you have factory SolidSteps then you likely will need to cut a portion of your siding to accommodate the mounting bracket for these steps and will also need the outrigger brackets # LC301704.
If you want a step that doesn't require cutting but also will stick out from... view full answer...
In order to find the correct leaf springs for a trailer you need to know their type (slipper/double eye), axle capacity, and unloaded length. I have attached a full list of options below. The 6-Leaf Double-Eye Spring part # e64SR for example has double eyes, a 7,000 lb capacity, and 24-7/8" unloaded length.
Unfortunately, we don't have any way to look up parts for any given trailer. view full answer...

Disc Brakes: part # K2HR79 (1 Per Axle)
Inner Bearing: part # 25580 (2 Per Axle)
Outer Bearing: part # 02475 (2 Per Axle)

Your 100lb Worthington propane tank is going to have a Type-1 / POL outlet fitting so you could use the Camco Propane "Y" Adapter w/ Handwheel - Male P.O.L. x (2) 1"-20 Male # CAM59893 which will give you two 1 Inch-20 - Male fittings to use whatever hose size you need like the MB Sturgis Propane Adapter Hose for Small Appliance - Disposable Cylinder Ports - 12' # 100284-144-MBS.

The hub as well as rotors are cast iron for the disc brake kit from HydraStar you asked about:
- HydraStar Disc Brake Kit w/ Actuator for Triple Axle Trailers - 13" Hub/Rotor - 8 on 6-1/2 - 7K # HSE7K-TR1
They are dacromet-coated as well to help ensure corrosion resistance. I can verify for you that the HydraStar Kit # HSE7K-TR1 does in fact fit Dexter 7,000 lb axles, as they have the correct bearings (25580 and 14125A) and grease seal (GS-2250DL) for that axle. view full answer...
According to the manufacturer the 2022 Grand Design Momentum 381M is 42'9" long. Which means the Classic Accessories PermaPRO Deluxe # CA80-299-203101-RT which is designed to fit 5th wheels and toy haulers 41' - 44' long will in fact fit. view full answer...
The Gen-Y Hitch Shock Absorbing 5th Wheel to Gooseneck Pin Box # GY58FR will be compatible with the gooseneck ball hitch in your 2016 Ram 3500 Dually. It's rated high enough to handle the GVWR and pin weight of your 2016 Grand Design Momentum 397th fifth wheel but you will need to check the bolt pattern of your current hitch to confirm fitment.
The # GY58FR you referenced fits a 1621 bolt pattern so your current pin box will also need to be a 1621. If you can find the tag on either the... view full answer...
