Our competitors cold forge their shells and allow large tolerances for die wear allowing the possibility to have some parts too tight and others fit too loosely at the press fit diameter. These parts are built like anti-friction bearings with close tolerances and highly polished studs. Using high strength step thread on all the ball studs and nuts. This is a matched thread that allows the installer to spin the nut on by hand but when torqued, it provides the strongest thread available. XRF’s hot forging process improves the mechanical properties of the metal. This efficiency is particularly important when working with expensive materials, such high-grade steel. It also provides excellent consistency and repeatability in the production of parts. The hot forging process reduced waste generation also contributes to lower environmental impact. XRF uses many features to give us the most ‘Reduced Friction’ parts on the market. This all adds up to smoother steering, better handling and increased fuel efficiency. In addition, XRF had added many installer focused features aimed at reducing install times. Protective boots are made of “CR” compound rubber that is resistant to oil, grease, brake fluid, battery acid and road-level ozone. The boots seal around the stud with multi-lip seal also anchored to the housing to ensure a tight seal and easy installation. Chloroprene Rubber Duster Covers: Sealed Boots & Accordion Boots.
