Custom Works was fast becoming the most prominent name in dirt oval racing. From December 1985 to March 1986, the Landgraffs' consistent success with their still unnamed prototype chassis left their competitors begging them to build more cars. The second and third versions of the "Landgraff car," as it would become known, incorporated several new ideas such as nerf bars, full width front bumpers, and a front and rear chain drive with a centrally located reduction shaft.

Jerry and Brian built 26 cars between August and December of 1986. Every manufacturer had to have a Landgraff car in order to showcase their products. Owners included Bob Novak, Mike Reedy, Kent Clausen and Gary McAllister. During this period, each car was slightly refined until it evolved into the DOMINATOR IV kit, known world wide as the original 4 wheel drive dirt oval car. The DOMINATOR kit was introduced as a production kit in 1987.

In 1990 Jerry and Brian decided to try their hand in the 2 wheel drive class, taking 12 prototype cars to the Roar Nationals in Dallas, Texas. The drivers included Joel Johnson, Chris Smith, Chris Doseck, Bob Light, Rob Cutman, Kevin Stevens and Brian Landgraff. They proceeded to win both the Stock and Modified titles in their first attempt, putting seven of their prototype INTIMIDATORS in the Modified A-main! After eight months of continued refinement and the addition of direct drive, the Intimidator kit was made available to the public in March of 1991. This kit has set the pace of 2 wheel drive dirt oval racing ever since.
