Bearing Spacer Wide 5 DMI Duece-1/2

The Bearing Spacer Wide 5 DMI Deuce-1/2 is a precision aluminum spacer engineered for Deuce and a Half military trucks equipped with DMI Wide 5 hub assemblies. This component is essential for proper wheel bearing preload and alignment on vehicles where accurate hub geometry directly impacts braking performance, tire wear, and suspension longevity. The spacer maintains critical clearances between bearing races and hub shoulders, ensuring consistent contact pressure across the bearing set without introducing runout or radial play.

Constructed from aluminum, this Wide 5 spacer weighs 0.49 pounds and measures 4.85 by 2.85 by 6.75 inches, making it a direct OEM-spec replacement for factory applications. The material choice balances weight reduction with adequate rigidity for load-bearing duty while remaining corrosion-resistant in harsh field conditions. Proper spacer thickness is non-negotiable on military vehicles—incorrect bearing preload leads to premature bearing failure, which in turn causes hub lockup, uneven brake application, and potential loss of vehicle control.

This component is intended for mechanics, restorers, and fleet operators maintaining Deuce-1/2 trucks (M35 and variants) in active service or preservation. Whether supporting off-road recovery work, long-distance convoy operations, or restoration projects, users need precise OEM-spec replacement parts to restore bearing assemblies to factory clearance standards. The Wide 5 configuration refers to the five-lug bolt pattern common to vintage and modern military medium-duty trucks, distinguishing this spacer from standard civilian truck hubs.

Sourcing correct bearing spacers for legacy military vehicles is a common challenge, as many OEM suppliers have discontinued production runs. DMI Wide 5 hubs remain popular in the military vehicle community for their durability and availability of compatible components like this spacer, making it a reliable choice for those maintaining aging 6x6 platforms.
