Whether you’re hauling heavy, towing long, or working your Silverado or Sierra HD to the limit, this joint delivers the stability, control, and durability your diesel front end demands.\u003c\/p\u003e\n\u003cp data-start=\"668\" data-end=\"1091\"\u003eEach joint starts with a forged SAE 1045 solid steel housing for unmatched structural integrity and a hot-forged SAE 4140 Chromoly ball stud—polished and heat-treated for superior load-bearing strength. Apex’s military-grade acetal bearing, the same material used in U.S. military Hummer suspension components, ensures smooth articulation and long-term performance under the extreme loads of heavy-duty diesel applications.\u003c\/p\u003e\n\u003cp data-start=\"1093\" data-end=\"1576\"\u003eEvery component is CNC-machined for exact tolerances, induction heat-treated for consistent metallurgy, and E-coated for corrosion resistance. A compression-style CR rubber boot seals out contaminants and retains lubrication, while the angled pre-threaded zerk housing makes servicing quick and clean. With gull-wing grease grooves, pre-greased internals, and Grade 8 hardware, the Apex Super HD Ball Joint sets the standard for durability and serviceability in GM Duramax platforms.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHOUSING\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSAE 1045 Solid Steel Forged Housing: This is unequivocally the best carbon alloy steel for this application.\u003c\/li\u003e\n\u003cli\u003eKnurled Housings: The preferred design for aftermarket installations.\u003c\/li\u003e\n\u003cli\u003eCNC Machined Housing: Make our parts and bearings dimensionally perfect, eliminating any die wear issues.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eBALL STUDS\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSAE 4140 hot forged Chromoly Ball Studs: For the strongest possible metallurgy.\u003c\/li\u003e\n\u003cli\u003eInduction Heat Treated Ball Studs: Provides a very precise heat treatment to the exact depth and location we want it.\u003c\/li\u003e\n\u003cli\u003ePolished Ball Studs: Are built like an anti-friction bearing with extremely precise tolerances.\u003c\/li\u003e\n\u003cli\u003eRolled Threads: Are made by pressing the shape of the threads into the ball stud instead of cutting.
