GReddy...a proven winner
Founded in Japan in 1977 The Trust company LTD has become a dominant source for automotive performance products around the world.   Since 1994 the development and distribution of Trust Company products in the United States has been accomplished by GReddy Performance Products, in Irvine California.

Founded and Driven by racers
A company founded and managed by racers and enthusiasts, GReddy Performance Products, Inc. has one prime goal, to develop products that increase performance. To this end, the GPP spirit of constant evolution shows in every product we offer. The reputation of the GPP line for US spec and JDM vehicles in unsurpassed and backed by a sales and service organization second to none. In our Irvine facility we maintain large inventory of products. Our application listings are extensive, covering most of the popular vehicles with a broad variety of products. We employ a constant customer awareness program with a feed back channel, which is used to further improve our product lines.

Real Technical Support
GReddy Performance Products, Inc. maintains an in-house tech-support center, staffed by knowledgeable personnel with years of experience, which not only gives immediate support to customers, but also is incorporated into the feed back channel to assist in constantly improving each and every product line. We do not outsource our technical support as we feel that when you purchase a
GPP product, you did it because you wanted the best, and quality tech support is part of the deal.

Warranty You Can Count On
At GPP we take our image seriously and back our products with a real warranty you can count on. In most cases, after examination of the item we will elect to give you a complete new product as opposed to repairing a defective one. We do this for two reasons, first of all to make you a completely satisfied customer, and secondly because warranty items are fully examined to find the cause of a defect and if necessary make running changes to the product line in the future. This is why GPP maintains one of the lowest warranty claims percentages in the industry.

Peformance Products
GPP maintains a wide varity of performance products, from CARB exempt 50-state legal performance products to "race only" products designed and intended for off-highway use. Whether you are just looking for a little better performance from your street machine, or are going for all-out race performance, the only name you need to know is GReddy Performance Products, Inc.  Please check your local laws regarding vehicle modification, before purchasing.
