Ball Joints by Alloy USA®. The Alloy USA HD ball joints were designed with a low profile (grease) zerk fitting, a feature not offered on factory replacement parts. Inner insert is replaced by a high strength steel socket. (Replaces factory plastic nylon insert). This steel insert increases Ball Joint strength. This is a must for lifted vehicles running tires larger than stock. Ball and socket use an exclusive threaded preload system that prolongs Joint life. Ball and shaft are constructed from SAE 4150 Chromoly steel.

A lot of horsepower under the hood and big, high-traction tires on the ground is a combination that can quickly reveal any weakness in the drivetrain. To make sure their drivetrain parts can withstand the rigors of racing and off-roading, the engineers at Alloy USA develop, test, race, and trail ride every product until it's perfected. Design that is refined through racing and rigorous testing is then made into the final product using the finest materials and the latest manufacturing techniques.
Alloy USA® is a division of Ultra Axle LLC, an affiliate of Omix-Ada, Inc., which is based in Suwanee, Georgia. The company manufactures axle shafts and other drivetrain solutions for racing and off-road vehicles. Alloy USA marries the mechanics of engineering with the art of manufacturing to produce the finest drivetrain products. Horsepower is useless unless you can get it to the ground, so Alloy USA engineers develop, test, race, and trail ride each product until it's perfected. Then, and only then, can it be sold to you the customer.

It had been three days since install and took it to a shop for alignment and was told one of the lower joints were busted. So they wouldn't do an alignment. Pretty annoying. I don't understamd how they can be busted if brand new.
