I just put the 1500lb (black) Sumosprings on mine...

'16 F150 SCAB, 6.5 bed, factory tow, 2wd.

Truck had some pretty good sag with a load of firewood in the bed, and a little towing the travel trailer, although I do use an Equalizer WDH.

Was a little bouncy with the travel trailer. I was looking to go either helper spring or the Sumo's.

I chose the Sumosprings. The install was simple. The drivers side has all the brake lines and wires clamped to the axle in a spot where the Sumo would have rubbed on them, so I took one brake line out of its clamp and bent down a metal tab that had the elec.park brake line clamped to it. Zip tied those secure and out of the way.

I left the 1" spacer in the set up. The Sumosprings make contact with the axle the whole time. I do have a big ARE MX series cap on the bed, about 250lbs, which put a little sag on the susp, where the rake of the truck was almost gone before the Sumos. Not really a sag, but the truck sat level with no rake with the cap on there.

After the install, the rear fender well to ground measurement went up about 1" The truck has the stock factory rake look again. The empty ride is stiffer. Bumps and bangs do bounce you around a little, but as nice as the soft factory ride was in this truck, it now feels more like a pickup... in a good way!

With a small amount of weight in the bed the ride is back to the stock feel, even better I think. Feels alot more stable cornering.

With a good size load of wood in the bed, about 1000lbs or so, the sag is gone and the truck rides and handles great. Feels like an F250 with the load.

I am real happy with the Sumo's!

I am looking forward to the weather breaking and we start towing the camper again. I am guessing it will feel alot more stable and, even with the WDH set up correctly, the bouncy rear end will go away.

I have been carrying around 4 battery cases that weigh about 80# apiece for winter traction. With the 1500 Sumo's, couldnt tell they were back there. Truck still needs help to feel as planted as the 14 was, but that was a RWD vs 4WD. It's better with the Sumo, but I feel the truck needs more.

I buy Sumospring for my F-150 2016 CC HDPP 4x4. ssr-117-47 kit, 1500 lbs.
I towing fifth wheel 7500 lbs loaded. truck sag 2-5/8" with about 1600 lbs pin weight + 200 hitch

I choose sumospring because they are smoother than timbren.
It is winter here in canada, i will install sumo in few week. I wil review about it,

I have a 2013 F150 4x4 HDPP and I received an email from super springs / sumo springs only the super springs will fit and not the sumo springs.
No clue why, they didn't explain why.
If i recall properly, I still have their email. Does anyone else know why?

2016 model HDPP have GVWR 7850 lbs. Il also receive email from superspring and they recommand sumosprings for my truck and base on my need.

Could be due to the Sumo springs replacing the bump stops and with the HDDP springs, they may not be as functional as they should be? When loaded the Somo's rest on top of the axle and compress, with HDPP, my guess is they don't compress enough to be of any use.

jeffinthebag

That would be my only guess too. The rear sits about 1 inch more between the axle and frame. But if they had a 1 inch optional spacer like timbrens then it should work. Supersprings gave me no answer except use the Supersprings and not the sumo springs.

I am going to remove mine and put the stock ones back on and see if there is any difference in ride quality while empty. This way they can't blame a "mod" for causing the issues with my truck. Hope they don't point to the Bilstiens and try to blame them either.

Howdie, may I add my 2cents.
We pull a fiver with a '13 XLT 150 Eco HDPP. Have considered adding some extra suspension cuz every now & then it will feel like it bottoms out when it hits an uneven surface. like a bridge entrance. Other than that the ride is fantastic & it pulls it with ease. Trucks rear, sits 2 inches higher unloaded and 1/4 inch higher than the front with the fiver attached (loaded PW 1450) So we get pertnear a 2 inch drop & the fiver tows a smidgen high in the front (1/4 inch). I'm afraid if we add any thing other than maybe Timbrens, the rear of the truck would be to high causing the fiver to ride even higher in the front. Decisions, Decisions, Decisions.

13ebf150. I have the 2013 5.0 crew HDPP. If you do a search, most HDPP will go with the timbrens or the Supersprings. I went with the timbrens and I know 2 others with the HDPP pulling a fiver went with the Supersprings I think saa8. They are on the forum. Supersprings with five the empty rear a 1 inch raise where are the timbrens will not. The other option and there is a review out there on it ( our years 2010-2014 and HDPP) is the Stable Load Torklift. Only problem I saw is we have a extra leaf spring compared to the regular f150s. So the clearance between the leafs is pretty tight for the piece to swing in. You would have to swing it in before hitching or loading the truck. Air bags are a over kill for our HDPP. I went with timbrens on this truck and my old truck I used Supersprings. Sumo spring will not work on our trucks. Keep me up date don which way you go.
