Hey Craig! The RAS # RAS3611-YHD comes with bump stop spacers and you will want to install them on your 2024 Ford F-150. The only exception is if you already have something like SumoSprings or Timbren SES installed in place of the factory bump stops.

What do you typically tow or haul with your F-150?

I purchased the RAS for my 2023 f150. I pull a 34ft camper with a Propride hitch. I'm very pleased with the set up. No proposing or saging rear. Towed from Ohio to Idaho 4 different times. Glad I purchased the RAS. So much better.

I purchased the RAS suspension system. It was a breeze to install and works great. It really helps. Take all the SAG out of the truck when you’re fully loaded. I have hauled a lot of material with it and it rides so much more comfortable. When the truck is empty, you can’t tell that they are there. I recommend them to anybody.

I placed the RAS on my 2022 F150. I just returned from pulling a 35' pull behind toy hauler from Wisconsin to Florida and back on a 2 week vacation. Helped with stability and no sagging tail when combined with an Andersen WDH: also provides a more sporty feel when driving with nothing behind. All things considered with a couple passengers and the trailer with a motorcycle and 30 gal fuel and 60 gal of water we run pretty close to max combined load. Still the truck and trailer handled fine on our 3500 mile trip.

I bought these but have not installed them yet. Do I have to remove the Timbrens I have installed and install the factory bump stops to work with the RAS? If I need to use the factory bump stops, are the spacers required and do they need to be modified like I saw in one of your install videos?

@JohnV since you have the # RAS3611-HD, you may be able to leave your Timbren # TFR1504E installed, but you'll need to check the clearance between the Timbrens and the RAS axle brackets once everything is installed. The two systems can physically fit together, but clearance is tight and you don't want the Timbrens contacting the RAS brackets as the suspension moves. If you have adequate clearance you can leave the Timbrens in place and won't need the RAS bump stop spacers. If there is interference, I would remove the Timbrens, reinstall the factory bump stops, and use the spacers included with the RAS.

@RobinH Hi there, my kit did not come with bump stop spacers, When I ordered the kit, I specified that my truck is a 2023 Ford F-150 XLT 4x4. Every install video I’ve watched and AI search I’ve done says that I need the spacers to create clearance for the RAS system and ensure that it doesn’t contact the bump stop. How do I go about getting the spacers sent to me?

@JohnV I see the issue. The # RAS3611-HD you ordered is for 2WD models. Since your 2023 F-150 is 4WD, you need the # RAS3611-YHD, which is the kit that includes the bump stop spacers. You can check with RAS to see if they can just send you the spacers and confirm whether there are any other differences between the two kits.

The brake wire providing voltage is wired in parallel, with one lead from each magnet being grounded to the trailer frame. We have a great Wiring Help Page that shows a diagram, I will provide a link to it below.
