SSA28 | SuperSprings for Ford F-150, Chevrolet|GMC Silverado|Sierra 1500, Nissan NV 1500|2500|3500, black

The leaf spring pack on my 2004 F150 was riding past the overload with a 1200 pound load. The truck was also sitting lower than stock thanks to the sag when unloaded. While SuperSprings advertises about an inch of lift, I got closer to 1 1/2 inches of lift using the pre-load setting. She doesn't feel any stiffer than stock and reacts far less to wind, passing vehicles, and uneven roads. I've only had about 600 or so pounds in the bed since I've installed them, but she's still sitting higher with no sag. Side to side movement is under far better control and there's a noticeable decrease in body-roll through turns.Installation was as simple as the online videos and instruction manual make it. The PSP goes on the center plate of the existing spring pack. You throw the front shackle on, don't over tighten it, and then compress the rear of the spring in order to bolt on the rear shackle. I needed more lift so i pre-loaded the shackle by selecting the uppermost bolt hole. Make sure the rear roller is clear of anything. You need about an inch of clearance. The front only requires about a 1/4 inch as the rear is doing most of the moving.The SuperSprings were installed along with a Timbren's SES, Rancho RS9000XL rear shocks and Rancho RS999910 Quick Lift Loaded struts.

I have a B&W Turnoverball Gooseneck Hitch and a Anderson Ultimate 5th Wheel Connection - 3225; SuperSprings SSA28 Self-Adjusting Suspension Stabilizer and Timbren FR1504D Suspension Enhancement System on rear of my 2013 F150 5.0 4x4 3.73 (6 1/2 bed) (all made in the U.S.A.), I have a Reese Revolution on my 2014 Rockwood 8289. I installed the Anderson Hitch so the coupler is centered with the rear end; I did not install the coupler forward toward to the cab. The SuperSprings and Timbrens are to eliminate squat and the "chucking". The SuperSprings were very easy to install, my wife and I installed them in our driveway (30 minutes). When I am not towing the truck rides ok because the springs do not engage unless there is weight applied.When towing my truck and trailer, everything is level; and because the full load is not being applied to the factory springs I do not have the rear sway (loss of stability). The maneuvering with turning and parking is easy and more than enough room between the cab and front the 5th wheel. Overall I am very satisfied with the performance of all products.

Work great.

Read somewhere that it might stiffen ride quality without towing but it actually rides smoother now. Very pleased! Took an hr to install. Used a c clamp to hold in place and bring the one side down to bolt in the brackets. My c clamps are I believe 4”and a little small to get it on over the helper spring and my leaf springs, so I had to push down the end of the helper spring with my hands and was able to get the c clamp on. Every easy! Rides smooth and will fully test it out in two weeks when I pull my camper trailer 4hrs up north. But as of now I’m super happy!

Fit nicely on my 2005 F-150 4x4 Lariat Crew cab with 5.5 bed. Used to help tow my 7700 pound travel trailer. Did raise the ride hight of the rear about 1.5 inches over stock. When I stalled them I jacked the rear of the truck up, removed both wheels and put two jack stands on the frame (not the axles) to allow the suspension completely relax. By doing so I installed them easy without the use of "C-clamps" or any other "speciality tools". Taking my time and doing this with zero rush it took me maybe an hour including jacking up and using stands.

This spring fit my 2008 F-150 despite the Amazon page saying it would not. I called the company prior to ordering it to confirm the fit. They went on fairly easily although I had to run the bolts in opposite from the instructions. They tell you to put the bolts in with the nuts toward the outside of the truck. You can't do this because the bolt is too long and there is not enough room between the spring and the truck frame to get it in. It works fine by putting it in from the outside toward the frame. I put it on the highest setting first and it resulted in the truck being jacked up about 2 inches. I decided to try it on the lower setting and it resulted in an increase of about an inch -- clearly noticeable. I don't notice any difference in the ride. I put these on to help prevent the sagging rear end when I tow a trailer with a tractor on it. They help.

I ordered and received the Super Spring (SS) P/N SSA28 for my 2018 F150. I started installation on the passenger side rear. I do not have a lift to do the installation. After raising the rear tire off the ground I started the installation. When the SS spring was centered on the truck springs the shackles that are provide with the installation kit would hit the clamps on the truck springs. See enclosed pixs. I spent about an 1.5 hours trying to get the SS spring to fit. Finally called the factory. Left a message for a tech call me back and it only took about two hours to get the call back. They had several suggestion. I did try them. Unfortunately, moving the shackles forward to clear the factory clamps would cause the SS shackles to hit the frame under loaded conditions. Next suggestion was to put the SS shackles behind the factory clamps. They may work but the roller was on the very edge of the truck second spring. Under load it probably would work fine. My concern is unloaded and hit a dip the roller would be only off second truck spring and only on the upper truck spring. I returned the SS spring to Amazon.After returning the SS spring I bought a Hellwig 978. The installation went very smoothly and does the needed job at half the price. The 978 is also adjustable which is a plus. It took about an hour for the initial installation.Bottom line is SS tried to make this spring a more universal fit. It would be great if SS would make one for the 2018 F150 about 2.5 inches shorter to fit my truck, ie clear the existing truck spring clamps. The SSA28 seems to be a good quality spring, but not for my truck.
