Overall Assessment

Customers overwhelmingly appreciate the product for its performance-enhancing qualities. They report a smoother drive experience, improved handling, and suitable lowering capability. Buyers acknowledge the springs as high-quality and a substantial upgrade over stock springs. The easy, hassle-free installation process, particularly noted when done by two people, is another significant advantage. However, customers mention problems with the ubolts' length and insufficient thread issues requiring additional washers. Despite these small inconveniences, our product's reliable, performance-boosting qualities lead many customers to confirm they would buy again and recommend the product.

As advertised

Sometime early in the life of my truck it got the old school lowering by mounting the stock springs under the axle. The ride was harsh and I felt it sat too low. I was going to fab airbag mounts till I ran across these. They raised the front about an 1 1/2" with a greatly improved ride. I bought the shacle kit and have extra bushings as these spring come with new bushings.

Great springs, bolts ... meh

Springs are a great improvement over the stock worn out springs. Softer ride over bumps (e.g., railroad tracks, differing payment heights). Not too hard to install, but it's a lot easier with two when installing the rear eyelet in rear hanger; one to push/pull on spring, and one to insert the pin/shaft. The ride height did drop, but not too much in my case (3/4") since one of the previous owners had taken two leaves out of the eight leaf springs. Major issue are the ubolts. First, they didn't have the shorties that go with the springs so they sent the long ones (much longer). Second, the threads don't go high enough on some of the bolts which require washers be used between the nut and mount on the front axle. Didn't realize it until I had threaded a few of the nuts to the top of the treads and they weren't contacting the axle. Had to remove the self tightening nuts, install some washers I had on hand, and reinstall (on those long bolts). Guess I should have checked the threads ahead of time. Will go back in a few days and replace those washers with grade 8 washers, plus add them to the other bolts that had ok threads.

The previous owner of my 50 Ford PU w/390 lowered the front end by removing a couple of leafs in the front. Looks nice but, the pan hits the front axle when driving on a rough road. So bascially, I have no front suspension. If I replaced the front springs with this product #580152 - will the axle still be an issue or do I need to install a drop front axle?
