Overall Assessment

Customers are generally satisfied with our product's quality and performance as it provides a perfect fit for their vehicles. The springs are well-made and easy to install, contributing to a more comfortable ride. The product also impresses with its specific design and material quality, effectively improving the vehicle's stance and handling. However, some customers mention that the U-bolts included in the kit do not meet their expectations. Therefore, while the springs' quality is praised, the accessory parts could be improved. Despite this, most customers would recommend our product for its confirmed qualities.

Good springs

I got these springs because the previous owner had torched the old springs so bad I was sitting on bump stops. They ride pretty decent so far, I've put about 20 miles on the truck over not so good roads, and it rides decent. I really wish they would have made the springs center the wheel in the wheel opening. When lowering a truck like this, the suspension travel isn't there in the shackles anymore to necessitate keeping the wheel so far back in the wheel well. Overall a decent product though.

not working as exspected

installed springs reverse eye to front hanger as instructed-spring center pin moves axle back about 3/4 from factory and throws the steering wheel off-also right turns not as sharp as left turns-theres no drag link adjustment and you can't reclock the pitman arm on a 54 f100-tried switching springs around steering wheel only slightly off center but with having the reverse eye in the rear hanger the lower second leaf binds/catches on spring hanger and pops-wasent really after the lowering just wanted a better riding spring-reinstalling old springs.

I called you about the springs. You said look in to and get back to me . You did not do that. No one got back to me at all. 1 side is lower there the other side is higher, The spring is weaker on the right side.

I've always received exceptional service when ordering parts or seeking advice But shipping has always been kind of sluggish most times; ie. days pass before packaging, item packaged and waiting carrier pickup, just slow, when compared to other big box parts store.

Overall these are pretty good springs I have nit driven too far on them because I am still working on lowering the back of the truck to match but so far so good. It moved the steering wheel position so i had to take the steering wheel off and realign that but that was the only issue I guess it does this because it moves the axle back a little but I saw no issue the wheels still fit in the fender nicely.

I purchased these springs and just finished installing them. The springs themselves are great. They are quality pieces that fit well and installed as expected to the chassis. The bushings were correctly sized and did not need to be reamed to fit the pins. They lowered the truck 2 1/2" from stock, but I expect it to settle a bit more as they break in. I have not yet driven it. On the other hand, the replacement shorter u-bolts were a joke. Total waste of time and material. The first issue was the diameter. The originals were 1/2" and the replacements were only 7/16". The second issue is that the original u-bolts were two different lengths. The front bolt is 1/2" longer to accommodate attaching the lower shock mount. The replacement bolts were just one length and too short to attach the shock mount. No shocks and undersized bolts might be fine for a trailer queen, but if you intend to drive it that is NO BUENO!!! The included nuts were Nylocks - fine for a garden trailer but not the correct nuts for automotive axle u-bolts. Posies should know better. I threw the hardware away and purchased quality custom u-bolts to mount the axle.

I purchased a set of Posies Super Slide Drop Springs for my 55 Ford F-100 to replace the original springs. I havn't road tested the truck, only installed to check fit, then removed to paint, I'll update this review after the road test. Pros: At first glance the springs look very nice, well made. I love the stance of my truck after install. The old springs didn't have much spring left and the truck leaned to to one side. The new drop springs didn't cause my axle to move back and appears to be in the correct stock location. I haven't found any steering issues by turning the steering wheel back and forth while on jack stands. Just a side note, I rebuilt my drag link, spindles, kingpins, hubs, and I am using all new installation hardware. Cons. The topside of the spring center bolt looked like it was hacked off with a set of bolt cutters, but wasn't an issue I needed to shorten it some to reuse my original u-bolt tie plate. It is recommended that you test fit the springs before painting, I did as they recommended. The springs are bare steel and shipped coated an some sort oil to keep them from rusting.
