GM Diesel Trucks & SUVs

NOTE: this is older site, for latest up to date information refer to the New site is at
www.a1customs.com

 The purpose of this website was originally to document some of the testing data of performance and other modifications as I made them on my GM Truck equipped with the GM 6.5L Turbo Diesel engine.  Having been somewhat disappointed in what the automotive aftermarket had to offer for these engines I went to work...

 Being that I've been involved in the automotive industry 24 years or so, I'd been and am designing things where I saw and see needs or better ways to achieve goals.  So I have created and thoroughly tested some products here and the designs that are unlike others and fill areas that needed much improvement, information those and other items is here on this website.

 Due to the many inquiries and interest in what we've done over the years, what started out many years ago as what some called a "serious hobby" to create some 'fixes' for the short comings of my truck and those of some friends, has now become website.  The need for these designs has had many asking, "will you make me one?", "are you going to be selling these things" "will you be coming up with a fix for?", etc...

 So we decided to produce or have produced these items in limited quantities and make them available, to owner's of GMC & Chevrolet Pick-up Trucks & SUVs with the GM 6.5 Liter Turbo Diesel Engine, information on them is here on this site.

 With my added interest in the new GM Duramax 6600 Turbo Diesel Engine and the all new in 2001 Silverado HD & Sierra HD trucks, I have added pages on my visits to the SEMA 2000 [specialty equipment market association] which was primarily open to those in the industry and the press, and was held in Las Vegas NV, and I added pages on the GM 2001 HD Silverado/Sierra Power Launch Tour that visited Los Angeles CA.  I have been asked already if I will offer enhancements for the new Duramax, we have some already and more are on the way.   

 This site will be updated regularly as things progress, so be sure to BOOKMARK it in your 'favorites'  and be sure to check back, or email Jim at a1customs(AT)aol.com for updates.
