Premium Hummer H1, H2, & H3 Products

G. T. Incorporated was created in 1994 by Tom & Sharon Cepek to distribute the Hummer Products that we've designed, developed, and marketed, specifically for the Hummer H1, H2, & H3 vehicles.

Our goal is to increase the number of those product offerings with unique products of our own design and manufacture, while at the same time providing the highest quality available to the Hummer Owner.

Our affiliations and experience for the past 53 years in the light truck automotive aftermarket are wide and varied, including, but not limited to, one of the sponsors of Rod Hall International for more than 20 years, 30 years as a member of S.E.M.A., 1986 SEMA Person of the Year, former owners of Dick Cepek, Inc., Four Wheel Drive Instructor for the Los Angeles County Sheriff's Department, and named Retailer of the Year by a prominent magazine publishing group.
