SuperSprings SSA28 | 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.

These are quality helper springs that are easy to install and maintenance free!

Easy to install, did inprove the ride with quad in back and does not bang or ride hard when box is empty.

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.

Easy to install work great definitely buy again
