King Pin Reamer

The Hepfner Racing Products King Pin Reamer (HRP6107) is a precision tool engineered for sprint car suspension maintenance and assembly. This specialized reamer features a 0.859 inch-per-foot taper geometry and arrives with a protective steel case, making it essential for anyone involved in sprint car preparation and teardown work. The reamer's design ensures accurate king pin bore sizing, a critical measurement in sprint car steering geometry and suspension alignment.

With a weight of 1.37 lbs and compact dimensions of 1.3 x 1.2 x 9.9 inches, the King Pin Reamer delivers professional-grade precision in a portable format. The tapered design and steel construction are built to handle the demanding tolerances required for king pin work. The included protective case safeguards the tool during transport and storage, preventing damage to the reamer's critical cutting surfaces and ensuring repeatability across multiple jobs.

Sprint car teams and chassis builders rely on precise king pin bore sizing to maintain proper caster, camber, and steering response. The Hepfner Racing Products reamer is designed for users who understand that suspension geometry isn't negotiable—incorrect king pin bore dimensions lead to uneven wear, steering inconsistency, and potential safety issues. This tool serves mechanics, fabricators, and team owners who perform their own suspension work rather than outsourcing to a machine shop, delivering shop-quality results on the race shop floor or in the garage.

Hepfner Racing Products has built a reputation for supplying purpose-built components and tools to the sprint car racing community. The King Pin Reamer reflects that focus—it's not a multipurpose reamer adapted for racing, but a tool specifically engineered for king pin applications where precision and repeatability matter every lap.
