Hub Spacer Wide-5 1/8in Thick

The Coleman Racing Products Hub Spacer Wide-5 1/8in Thick (Part No. 17636) is a precision wheel bearing spacer engineered for Wide-5 hub applications. This steel spacer maintains exact axle geometry and bearing preload, critical for safe wheel assembly on high-performance and marine trailers where proper hub spacing directly affects bearing longevity and trailer stability under load and dynamic conditions.

Specified at 1/8 inch thickness, this spacer ensures consistent bearing clearance and eliminates radial play that can lead to premature wear or overheating during extended towing or high-speed operation. The steel construction resists corrosion and maintains dimensional stability across temperature variations common in marine and saltwater environments. Coleman Racing Products holds a reputation in the motorsports and trailer industry for precision component manufacturing, and this spacer meets the exact tolerances required for reliable Wide-5 hub compatibility. Each spacer ships as a single unit, allowing for targeted replacement or complete axle assembly rebuilds.

This component is essential for boat trailer owners, offshore anglers, and anyone maintaining Wide-5 equipped trailers in marine service. Salt air and repeated wet/dry cycling demand attention to bearing condition and spacing—proper spacer thickness prevents binding and excessive friction that accelerates corrosion and bearing degradation. Weighing just 0.09 lbs, the spacer is lightweight yet dimensionally precise, fitting into standard Wide-5 hub assemblies without modification.

Wide-5 hubs remain the standard on utility, boat, and enclosed trailers across North America. Whether replacing a worn spacer or performing preventive hub maintenance before the boating season, having the correct 1/8 inch thickness ensures bearing preload is restored to specification and trailer handling remains safe and predictable.
