Instead, they rely on an ultra-rugged, industrial-grade kingpin configuration. The lower section of this system utilizes a precision-machined, hardened steel kingpin that mounts tightly onto the knuckle shell and seats down into a heavy-duty tapered roller bearing within the inner C-axle ear. Over decades of heavy commercial hauling, farm work, or trail riding with massive off-road tires, this lower pin can develop deep pitting, rust scars, or flat spots due to moisture intrusion or lack of grease. A worn lower kingpin introduces structural slack into the steering knuckle pivot axis, leading to severe tire cupping, unsafe steering wheel shimmy, low-speed clunking, and a total loss of front-end alignment stability.\u003c\/p\u003e\n\u003cp data-path-to-node=\"9\"\u003eThis original equipment manufacturer (OEM) replacement component is forged by the industry’s benchmark drivetrain supplier from premium-grade carbon-alloy steel, induction-hardened to exact case depths, and ground to microscopic factory tolerances. Choosing a genuine Spicer kingpin guarantees uncompromised metallurgical density and a flawless fit into your factory steering knuckle, avoiding the rapid wear or loose housing tolerances common with cheap aftermarket alternatives.\u003c\/p\u003e\n\u003cp data-path-to-node=\"10\"\u003e\u003cb data-path-to-node=\"10\" data-index-in-node=\"0\"\u003eComponent Features:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul data-path-to-node=\"11\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"11,0,0\"\u003e\u003cb data-path-to-node=\"11,0,0\" data-index-in-node=\"0\"\u003eIndustrial Forged Strength:\u003c\/b\u003e Precision-manufactured from high-tensile alloy steel to support the immense front-end weight of heavy iron-block small block\/big block gas engines or early diesels, along with commercial utility attachments.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"11,1,0\"\u003e\u003cb data-path-to-node=\"11,1,0\" data-index-in-node=\"0\"\u003eMicro-Ground Seating Surface:\u003c\/b\u003e Features a mirrored, ultra-smooth outer taper to ensure uniform load distribution across your lower kingpin tapered roller bearings.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"11,2,0\"\u003e\u003cb data-path-to-node=\"11,2,0\" data-index-in-node=\"0\"\u003eRestores Alignment Accuracy:\u003c\/b\u003e Re-establishes a rock-solid lower pivot axis to instantly clear up lane drift and stabilize steering knuckle geometry under extreme load.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"11,3,0\"\u003e\u003cb data-path-to-node=\"11,3,0\" data-index-in-node=\"0\"\u003eGenuine Spicer OEM Quality:\u003c\/b\u003e Engineered directly from original blueprint dimensions to guarantee hassle-free installation and strict compliance with factory strength parameters.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-path-to-node=\"12\"\u003e\u003cb data-path-to-node=\"12\" data-index-in-node=\"0\"\u003eVehicle \u0026amp; Axle Fitment:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul data-path-to-node=\"13\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"13,0,0\"\u003e\u003cb data-path-to-node=\"13,0,0\" data-index-in-node=\"0\"\u003eAxle Profile:\u003c\/b\u003e Solid Mono-Beam Low-Pinion or High-Pinion \u003cb data-path-to-node=\"13,0,0\" data-index-in-node=\"56\"\u003eDana 60 Front Axles with Kingpin Suspensions\u003c\/b\u003e. \u003ci data-path-to-node=\"13,0,0\" data-index-in-node=\"102\"\u003eDoes not fit later ball-joint style Dana 60 or Dana Super 60 configurations.\u003c\/i\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"13,1,0\"\u003e\u003cb data-path-to-node=\"13,1,0\" data-index-in-node=\"0\"\u003eChevrolet \u0026amp; GMC K30 \/ K3500 Pickup \u0026amp; V3500:\u003c\/b\u003e 1977, 1978, 1979, 1980, 1981, 1982, 1983, 1984, 1985, 1986, 1987, 1988, 1989, 1990, and 1991 1-ton 4x4 trucks equipped with kingpin Dana 60 front axles.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"13,2,0\"\u003e\u003cb data-path-to-node=\"13,2,0\" data-index-in-node=\"0\"\u003eFord F-350:\u003c\/b\u003e 1978–1979 and 1985–1991 dually and SRW 1-ton 4x4 trucks running open-knuckle kingpin Dana 60 housings.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"13,3,0\"\u003e\u003cb data-path-to-node=\"13,3,0\" data-index-in-node=\"0\"\u003eDodge W250 \/ W350 Pickups:\u003c\/b\u003e 1975–1993 heavy-duty 4x4 trucks (including all 5.9L Cummins Diesel and V8 configurations).\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"13,4,0\"\u003e\u003cb data-path-to-node=\"13,4,0\" data-index-in-node=\"0\"\u003ePosition:\u003c\/b\u003e Front Outer Axle Steering Knuckle — Lower Position, Left (Driver) or Right (Passenger) Side. \u003ci data-path-to-node=\"13,4,0\" data-index-in-node=\"103\"\u003e(Note: Sold individually; two pins required if overhauling both sides of the front axle).\u003c\/i\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Spicer","offers":[{"title":"Default Title","offer_id":43562419847242,"sku":"PLAT-SPICER-KIT120","price":45.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0706\/5560\/6858\/files\/10_cdde7231-4a40-4676-af34-7e35c58cf5e7.jpg?v=1777722337","url":"https:\/\/platinumperformanceparts.com\/products\/spicer-dana-60-lower-king-pin-77-91-chevy-gm","provider":"Platinum Performance Parts","version":"1.0","type":"link"}
