The 5-Hole Disk Brake Spacer (2) 3/8in Thick is a precision brake system component designed for custom and performance vehicle builds where wheel fitment and caliper clearance require adjustment. This spacer pair addresses a common challenge faced by mechanics and enthusiasts: achieving proper brake caliper positioning when upgrading wheels, changing suspension geometry, or adapting braking systems across different platforms. Whether you're fitting larger diameter wheels, transitioning from drum to disc brakes, or fine-tuning a custom build, these spacers provide the critical stand-off distance needed to prevent caliper-to-wheel interference while maintaining safe brake operation.
Manufactured by Racing Power Co-Packaged under part number R4082, this set features a robust 3/8-inch thickness and is engineered for the standard 5-lug bolt pattern found on the majority of North American vehicles. The spacers are precision-machined to ensure parallel mounting surfaces, eliminating runout that could affect brake rotor trueness and stopping performance. At 1.17 lbs total weight, the pair adds negligible unsprung mass while delivering the rigidity required to maintain caliper alignment under braking loads. The 5-hole configuration ensures compatibility across multiple vehicle platforms, making these spacers a versatile solution for engine swaps, chassis conversions, or brake system retrofits where OEM spacing is inadequate.
Professional mechanics and serious DIY builders rely on brake spacers when working with performance upgrades or non-original brake assemblies. Installation requires removing the brake caliper and rotor, positioning the spacer between the hub mounting surface and the caliper bracket, then reassembling with OEM hardware torqued to specification. Always verify wheel clearance before final assembly and test stopping power thoroughly after installation. These spacers are particularly valuable when upgrading to larger rotors, adapting calipers from different vehicle models, or accommodating wide-body wheel packages. Proper installation ensures consistent brake feel, prevents pad rubbing, and maintains the safety margins your braking system demands.
