Video Transcript for Fifth Gear 5th Airborne Premium Fifth Wheel Air Ride Coupler Installation

Today on our fifth wheel trailer we'll be installing the fifth airborne premium fifth wheel air ride coupler part number 5AB-E1621-610. Let's go ahead and show you how to operate the new air ride control on the fifth airborne coupler. We'll simply remove the plastic cap and apply air or pressure to the Schrader valve. This will blow up the bag and push down on the bottom plate of the coupler showing the line necessary to fill your airbag up to. Now, this will vary by vehicle and trailer but the line indicator here is a good starting point. Now, first, before we can install the new king pin, I'll need to remove the old or manufactured.

On this application, we'll need to remove the plastic cover around it first. There are a total of four fasteners to be removed. We'll remove the four fasteners and set the fasteners in plastic aside. We'll also remove or relocate any wiring that will be in the way, removing and reinstalling the pin box. In this application, we'll need to relocate and resecure the breakaway switch. We're removing now and then resecure it to the pin box once it's installed.

There's also wiring behind the pin box. To make it easier to access the hardware, we're going to go ahead and remove it also. Now, with all the wiring out of the way, we're ready to go ahead and start removing the manufacture's hardware. There are a total of five fasteners on each side. We'll remove six of the fasteners, three on each side completely and loosen four vaults. The two top ones on each side.

We'll leave in until we can support the weight of the pin box. Now, with all the fasteners removed or loosened, it will be necessary to get an extra set of hands or in this case we're going to be using a pallet and fork truck to help support the weight of the pin box. Once we bring it up under the pin box, we can then go ahead and remove the fasteners. Then, we'll pry or pull the old pin box down and out of the trailer brackets. Now, with our old one out of the way, we're ready to go and start installing a new one.

Once again, we'll use the fork truck to lift it up into position and get it close and then we'll move it around with an extra set of hands to install the hardware. We'll be reusing all the old or manufactures hardware to secure the new pin box. Once we have the hardware in place, we'll go ahead and tighten it down. Then, we'll work into specifications as indicated instructions. Now, with the pin box secured into our specifications, we'll go ahead and reinstall the wiring at the back of the coupler. Then, the new break switch using a self tapping screw, we're going to secure it here into the top of the new pin box. It will be out of the way to the coupler and the airbag in control. There you have it for the fifth airborne premium fifth wheel air ride coupler part number 5AB-E1621-610 on our fifth wheel trailer. .

Awesome Pinbox , bolt on as advertised , in retrospect an additional pair of hands would be helpful but I was able to install it by myself. The towing experience is a major improvement over a fixed pinbox 642372

The lady who helped me on the phone knew her products. The product shipped right away and was delivered in three days. It was delivered in good shape. it only took a couple of hours to install. That included messing around. There was two of us because of the weight and we were both senior citizens. Really appreciated the ease of installing. I purchased the product because of the jolt caused by the cracks in the cement when pulling my 5th wheel. Customer service was excellent 81804

Unit arrived in good condition. Was a breeze to install, about a 1 hour job with 2 people including removal of old Tri-Glide. Didn't like the "banging" back and forth with the tri-glide. The only issue I had was having to drill pilot hole for breakaway switch screw. Non issue! Can't wait to make a haul with it. Alaska here we come! 375578


Comments
We put over 9000 miles on our new setup. The difference in the ride was amazing! Wouldnt have any other setup. I did add airbags to the truck as well. At times we had to look back to see if the trailer was still there. Its a 40 ft. toy hauler towed with a F350 dually, 6.7 powerstroke.

The 5th Airborne Air Ride Coupler is very well made with quality welds. Installing on a 2010 Cyclone 3612 Toy Hauler, I did have to cut about 1/2 inch from the fiberglass at the top front of the Lippert Trailer Mount. This modification provided the 3/8" vertical movement required to allow the front 3 bolt holes to line up. Other than the small fiberglass trim, a very clean installation. 193795

Ask the Experts about this Reese Fifth Wheel King Pin

  • Upgraded Air Ride Pin Box Needed for a Lippert 1621HD Pin Box
    I do have a pin box upgrade for you, but unfortunately we do not have a Trailair Air Ride that is a correct replacement for your Lippert 1621HD. The 1621 and 1621HD have similar bolt hole pattern, but the HD has an extra bolt hole. This means that you can use an HD pin box for a 1621 application, but if you have an HD pin box that extra bolt hole needs to be used so the regular 1621 pin boxes are not compatible. The upgrade that we have is the Reese 5th Airborne Premium Air Ride Coupler...

  • Cushioned Pin Box that Can Fit 2000 Forest River Cardinal with Fabex 665/663 Style Pin Box
    Cushioned pin boxes aren't exactly super cheap, but the best priced option that would fit your fifth wheel that has either a Fabex 665 or 663 is going to be the 5th Airborne part # 5AB-E1621-610 which has an air bag and shock system in it that will cushion the ride.

    Since you have Mor/Ryde RPB72-1621SHD that means your trailer has a Lippert 1621 pin box. That means that the 5th Airborne Premium Fifth Wheel Air Ride Coupler # 5AB-E1621-610 that you referenced would be the correct air ride pin box.

  • Air Bag Adjustment and Required Air Pressure for 5th Airborne Air Ride Pin Box 5AB-E1621-610
    Some 5th Airborne units have the air bag adjustment bolts on the top of the housing, while others are located on the underside. The fact that yours adjusts from the underside does not represent a problem. 5th Airborne recommends moving the air bag forward for lighter pin weights and rearward for heavier pin weights. For the pin weight you mention, having the bag set in the center would work best. Beginning with 80-100 psi is recommended. You can adjust the air pressure upward (no greater...

  • 5th Wheel Hitch Adapter for 2015 Ford F-350 Super Duty With Factory 5th Wheel Prep Package
    Since your 2015 F-350 Super Duty has the factory 5th wheel prep package you'll want to use the Reese Elite Series Underbed Rail Adapter # RP30156 which is shown in the linked video. This adapter accommodates standard 5th-wheel trailer hitches with weight ratings of 15,000 lbs, 16,000 lbs, or 20,000 lbs. You can still use your 25K-rated hitch but the system capacity will be 20,000-lbs overall. I've linked for your reference an article on 5th wheel installation tips.

    For your 2014 Heartland Cyclone 3010 from what I can find online, you have a 1621 HD pin box from Lippert. For air ride, the only options we have currently available are both from Reese. The Reese 5th Airborne Premium Fifth Wheel Air Ride Coupler # 5AB-E1621-610 is a straight pin box and we actually have a video of this installation on a Cyclone trailer that I've attached. The 21,000 lb capacity will not be too much and will not make the ride too rigid because your air ride is adjustable....

  • Recommendation for Replacement Pin Box on a Lippert 1621HD
    I recommend you go with the Reese 5th Airborne Premium Fifth Wheel Coupler # 5AB-E1621-610. This pin box is preassembled and will bolt onto your trailer using existing holes and hardware. It will also help with the chucking you're having. It has a 3 year warranty and 21,000 lbs. capacity. If you're having clearance issues we offer the Reese 5th Airborne King Pin that comes with a Turret # RP61422. This setup has the same 3 year warranty but is only rated for 16,000 lbs. Assuming...

  • Air Pressure and Air Bag Placement Recommendations for 5th Airborne Pin Box
    The air pressure in the air bag inside of the 5th Airborne pin box # 5AB-E1621-610 should be adjusted after the trailer is hooked up to the hitch. The maximum air pressure for the air bag should not exceed 120 psi. With a pin weight around 2,600 pounds the forward most air bag position should be fine. But you may get better results by moving the bag back one notch. The further back positions are designed for heavier pin weights (the maximum for this pin box being 4,200 pounds). I have...

  • How to find 5th Airborne Premium Fifth Wheel Air Ride Coupler for a 2008 Keystone 5th Wheel Trailer
    To determine the correct 5th Airborne Premium Fifth Wheel Air Ride Coupler that will fit for your 2008 Montana, by Keystone, you will need to find the pin box model number and manufacturer that is on your trailer. The pin box manufacturer and model number is normally on a tag on the side of the pin box or on the face of the pin box. It could also be stamped in the face of the pin box in some instances. If you cannot find the pin box model number, you would then need to contact the trailer...

  • Is a Longer Pin Box Available for a 5th Wheel Trailer with Lippert 1116 Pin Box
    The replacement pin boxes that we carry are roughly the same dimensions as the pin boxes they are made to replace and would not provide you the additional 12 inches you are looking for. In order to get the length you need I do recommend a Sidewinder. For a Lippert 1116 pin box you can use: 16K Sidewinder only, # RP61410 19K Sidewinder only, # RP61411 16K Air ride pin box and Sidewinder, # RP61412 I have included links to our FAQ articles on Sidewinders and air ride pin boxes.

  • Replacement 5th Airborne Coupler And Wedge For Pullrite Fifth Wheel Hitch
    The 5th Airborne coupler you can use to replace your Lippert 1621, is part # 5AB-E1621-610. This king pin helps reduce shock and relieves stress on the coach frame. I have attached a link to an installation video for this coupler you can check out. If the Custom Wedge is what you are talking about that works for the 5th Airborne Coupler and your Pullrite hitch, you will need part # SWW-09.

    The difference between the 5th Airborne Premium Fifth Wheel Air Ride Coupler # 5AB-E1621-610 and the 5th Airborne Premium Fifth Wheel Air Ride Coupler # 5AB-E1621-16K is the weight capacity and a different bolt pattern. You would want the # 5AB-E1621-610 since your pin box is a 1621HD. The # 5AB-E1621-16K is only designed to work with the 1621 pin box so I would not recommend it for you.

  • How to Level 5th Wheel Trailer That is High at the Nose and Low in the Rear
    In your 2014 Ram 3500 with 5th wheel prep package the use of an adapter like the Pullrite ISR or the Reese # RP30154 is needed to install some types of 5th wheel hitches. These adapters add height to the set up, 2-inches in the case of the Reese, and that can lead to an out-of-level trailer. Your options are to replace the hitch with one like the Curt Q24 # C16545-16021 or the B&W # BWRVK3600 that install direct to your 5th wheel prep package, or to raise the height of your trailer...

  • Can a 5th Airborne Replace a Lippert 1621 Pin Box and be Used with Pullrite Superglide Hitch
    5th Airborne pin boxes can be used with a Pullrite Super Glide fifth wheel hitch. You will just need to find the correct capture plate to use with the new pin box. According to my research the correct one to use is the part number 88080, but we do not carry Pullrite products so you would still want to verify that. The correct 5th Airborne to use to replace your Lippert 1621HD that has a 21k capacity is the part # 5AB-E1621-610.

  • Hitch Trailer Before or After Filling Air Spring on a Fifth Gear 5th Airborne Pin Box Coupler
    First, hitch the trailer to the truck, then add air. Proper pressure level depends on many factors like truck used and what trailer the Airborne is on. Start at 80-100 PSI, if the ride is too stiff, let some pressure out. Too soft, add some more. Do not ever exceed 120 PSI. If you cannot get a good ride, then the air spring may need to be adjusted. See page 4 of the instructions. I would let most of the pressure out before you un-hitch the trailer from the truck.

  • Is there a Specific PSI rating for a 5th Airborne Air Ride Coupler when Storing in the Winter
    I spoke with my contact at 5th Airborne and he stated that you can leave the air bag inflated to the pressure that it is currently at provided it is within the recommended 80 to 100 psi range as indicated in the instructions. There is no need to increase or decrease the amount of pressure when storing the trailer because the air bag will not be under nearly as much stress as it is when towing.

  • Skid Plate on Reese 5th Airborne Sidewinder Isn't Level
    If the skid plate on the Sidewinder isn't level with 60 psi in the airbag, make sure you're on level ground, and ensure that the height of the fifth wheel head is adjusted properly to the fifth wheel is as level as possible. If the fifth wheel hitch head isn't adjusted correctly, it'd explain why the skid plate isn't level.

    In order to determine what Fifth Airborne your 2013 Flagstaff Fifth Wheel 8528TBWS would need you would first need to determine what pin box you have on your trailer.

With that information you will then be able to pick out the correct 5th Airborne. Check out the link I attached that has a chart that you will find which part number you would need.

    TrailAir pin box LC155930 is designed to fit the Lippert 1621 but not the 1621HD even though both have the same bolt mounting pattern. If the trailer weighs less than 18,000 pounds it would work. For a air ride pin box that is designed to work with the 1621HD pin box use # 5AB-E1621-610.
