Precision is a child company of Federal-Mogul, located in Southfield, Michigan. As a child of Federal-Mogul, you can rest assured that you are going to receive a top-notch piece of equipment from a trusted manufacturer. Precision's branded super strength U-joints are each CNC machined to meet, and often times exceed, original equipment standards. Each of the Precision U-joint components are ground to stringent tolerances with quality-control inspections at each stage of Precision's manufacturing process. The bearing cups that Precision manufactures are cold-formed and case-hardened, ensuring a strong piece of equipment that will stand up against the hard twists and turns that universal joints are put through. Each bearing cup is then precision-ground to improve wear and tear resistance, as well as overall strength.

Precision employs the use of abrasion-resistant nitrile as a coating substance in order to provide their performance seals with optimal grease retention and above-average protection from contaminants that the underside of the vehicle can come into contact with. Only high-strength steel is used to forge the crosses of each joint. They are then carburized and heat-treated to meet and most often surpass OE specifications for U-joints. This ensures durability when combined with needle bearings machined for maximum load-carrying capabilities. Grease fittings in the cross body allows for easy maintenance. Precision Super-Strength U-joints, ideal for performance, severe-duty and high torque application, are available in both greasable and non-greasable designs.

Non-greasable versions of Precision's U-joints feature grease reservoirs in the tip of each section of the cross. This ensures that proper lubrication is maintained through long periods of driving, and during racing conditions. Greasable variants have an included flush lube fitting on the inside of the bearing cup to allow for easy access and an easy method to refill the joint with fresh grease. Precision makes some of the finest universal joints available on the market, and supplies customers with everything they need to have their Mustang running smoother than ever before.
