GKT Kevlar

Vehicle Parts  /  Transit/Coach Bus  /  GKT Kevlar

ProTec's Guardian Kevlar Transit Extra Heavy Duty 28,660-lb axle-rated material is a powerful severe service block. GKT offers enhanced friction performance for maximum stopping power with low lining and drum wear rates across all temperature ranges. ProTec’s unique blend of insulating fibers, bonding resins and advanced graphites transfer heat away from lining/drum, minimizing brake fade and noise. 

GKT features a long kevlar textile fiber length, which reduces the unit loading on the organic materials in the friction mix and extends wear life by 30% compared to OE premium linings.

All linings are produced in ISO-9001, V20008 quality control standards.
