Dorman - OE Solutions Drive Shaft P/N:946-176
$516.99
Get your driveline turning again with the Dorman - OE Solutions Rear 2-Piece Steel Driveshaft Assembly (946-176), a fully assembled, dynamically pre-balanced unit that installs as a direct-fit replacement on the 2011-2013 and 2015-2018 Chevrolet Silverado 2500 HD and the 2011-2013 and 2015-2018 GMC Sierra 2500 HD. A driveshaft carries torque from the transmission to the rear axle; when the original wears, you may notice driveline vibration, a clunk on acceleration, or U-joint noise.
- Premium shaft: made from drawn-over-mandrel (DOM) seamless steel tubing for superior concentricity, uniform wall thickness, and more torsional strength and dent resistance than standard welded steel.
- Ready to install: arrives fully assembled and dynamically pre-balanced for a fast, hassle-free installation on the specified applications.
- All-new construction: built in the USA with 100% new—not remanufactured—tubing, yokes, and U-joints, shipped in protective foam-in-place packaging.
- Serviceable design: greaseable, with a slip-yoke end and a universal-joint end, and adjustable overall length.
Specifications: 3.5 in shaft diameter, 0.083 in wall thickness, 92.625 in length. Made in the United States.
Interchange: Manufacturer part number 946-176.
