Since 1960 the KING RACING company has designed and manufactured high performance/quality bushings. Beyond high-performance production machines, King Racing relies on simulation software to analyze the thermodynamics, dynamics and elasto-hydrodynamics of their bearings. KING RACING tri-metal bushings are produced in pMax Black, a tri-metal alloy 24% stronger than all existing tri-metal bushings.

KING RACING pads are made up of 3 to 4 layers (depending on applications):

Exterior: steel Intermediate: leaded bronze Interior: regulator with high percentage of copper Anti-friction Coating containing lubricant and ceramic additives
