At Hardin Marine we manufacture the finest high speed deep groove engine pulleys available. Each pulley is manufactured from 6061-T6 billet aluminum using Tru-Trac technology. Tru-Trac allows the V-belt to ride deep in the belt groove for maximum belt contact. Both the power steering and sea pump pulley use mandrel mounting features that protect the pulley from undue shaft heat. The most common cause for failure in lesser quality pulleys is caused from heat transferring to the pulley releasing from the shaft causing undue damage and safety hazards.
