Help me choose a bump stop kit

[QCRappy]

+3 would be the option if you plan on towing or load the bed. The +2 is stock height so you would essentially have a lower rear end when towing since you have a block in the rear as well keeping it at the heigh now.

When I had Noah customize my raptor he recommended me the rpg stage 2, and it seemed to do a great job on the recent poker run II i went on

@Taxman not sure if you are aware, but the SVC kit is the only kit available that is adjustable. The RPG kit requires the purchase of a additional set of bumps to be able to use for towing. This makes the SVC kit an exceptional value.

While you do not "need" to upgrade your leafs, it does make a good deal of a differance both loaded and un-loaded. In short, Deavers leafs are progressive rate (while OEM are linear rate) so they will ride slightly softer when empty but will progressively stiffen up as the weight increases (or as they cycle over bumps). You will notice a better overall ride quality.

Hit me up if you have any questions, we can also get you setup with the SVC kit and/or deaver combo.

With stock leaf springs and unloaded, how much space is there between the strike plate and the bottom of the bump stop at the lowest setting (tow/payload mode)?

My fear is that under a full load, the rear will sag from the load on stock springs and the bump stops won't be anywhere near the strike plate, negating the benefits of the bump stop.

The RPG setup, although not adjustable with bolts, uses a longer 4" bump stop that comes down further and is only an inch or two from the strike plate under a full load.

Not sure. I still need to research this further.

I also read that Deavers are not meant to be used with heavy loads or for heavy towing. Those of you that have Deavers, have you towed anything heavy, or just used them for desert racing and jumping?

The more weight you put in the bed or the more tongue weight you have from a trailer will bring the bumpstops closer to the strike pad on the axle.

@Taxman I have the SVC bumpstops and the deaver+3 springs on the truck I use for work(construction) I sometimes pull my 18' enclosed trailer when I don't feel like driving my F-450 and this setup make a huge difference not only towing but with my DD. There have been numerous times that I didn't feel like adjusting the bumpstops and the springs alone did just fine pulling around 7000lbs with barely any squatting. So if you have to choose just one for now I would probably start with the springs. Now I'm not a professional but if I had to go that route this is the direction I would go.

@Taxman

Please note, with what you have described, you don't need a bump stop kit. I would recommend a kit as a precautionary, but it's not necessary.

Every customer has a different set of needs / wants. I not going to sell you something you don't need unless you want it.

We offer a few different options as "adjustability"... Having towed a trailer for a long distance in a raptor, I feel that the 2.5" travel bumps are too short.. There just isnt enough travel.. Hence why we recommend the 4" Travel. In order to increase payload, you need to increase Nitrogen Pressure with the 2.5".. Increased nitrogen pressure increases impact harshness... When using the 4" travel, you can still keep a low Nitrogen Pressure and the added length keeps you from Negative Arching the Springs.

I will be more than happy to discuss this in detail. My cell 858-437-3167

All of these considerations go out the door when using a load leveling hitch. Easy / Simple

I tow a big trailer. A few people probably say too big. 30' Ragen toy hauler with a light weight of around 8k lbs. With the SVC kit moved down to towing mode and a weight distribution hitch it handles it perfectly fine. With a little fine tuning and some brains while towing the bump travel is a non issue. i have about 9000 miles towing on the bumpkit and have had maybe one instance of an unexpected rough bridge but it still didn't bottom out the bump. I set them at 135psi unless the trailer is empty. If my razr is in the back of the trailer I can back them off even more

I had about the same choice to make as you did years ago. I went with the @RPG kit over the springs. I wanted the added security (mental comfort) of reenforcing the frame. In stock for (towing a 5,000 lb SUV + trailer) I had good success and the bump stops did their job when they needed to.

I think all the companies make a good product, I am only suggesting you look at the bump stop it now, and springs once funds come available.

just my opinion

If I was to replace my kit, it would likely be to the Icon, or one of the other kits with King bumps. I am not a big fan of Fox right now.

Yeah, the more I look at the kits and my options, the more I feel like the bump stop is the way to go. I plan on using an Equalizer hitch with sway bars, so that should help control sway and reduce the sag on the rear springs. However, I just don't feel like new springs are really a priority right now. I think I just need to protect my existing stock springs from getting damaged if I hit a bump on the road and bottom out more often than normal.

I've narrowed it down to the SVC and RPG kits - purely from a cost/benefit standpoint. I like the RPG kit the best. From a structural standpoint, I think it offers the more solid setup. I don't like the mechanical connection (using just two bolts) of the bump stop to the frame mount. I prefer a welded mount.

Not sure if I would even need the 2.5" stops right now. I'm thinking of only getting the 4" stops and running them only when towing.

Thanks for all the suggestions.

I wish I was ready to sell mine, save you some $$$$.
