Power Technology has been manufacturing its valve and chassis spring tester products since 1992.

Our valve and chassis spring tester customers include many of the top racing teams, engine builders and manufacturers in the world, such as Hendrick Motorsports, Robert Yates Racing, Childress Racing, Warren Johnson, Bill "Grumpy" Jenkins, Cagnazzi Racing, Harley-Davidson, Toyota Racing Development, Katech, Competition Cams, Isky Cams, K-Motion, Lunati Cams and many other top engine builders.

Engines and Race cars set up using a Power Technology valve or chassis spring tester have won the majority of the most prestigious races and championships in the world, such as the Daytona 500, Brickyard 400, the Winston/Sprint All-Star Race, the Indianapolis 500 standing Lap Speed and Pole Position records and the majority of the NASCAR Cup Championships and NHRA Pro Stock Championships over the past 12 years.

Development of Power Technology's initial product, the PT-200 Valve Spring Tester began in 1992. A prototype system was shown to the top engine builders in racing, including Randy Dorton, Warren Johnson, Buddy Morrison and others. In particular, Randy Dorton of Hendrick Motorsports worked closely with the designers at Power Technology to insure that the PT-200 satisfied the demanding valve spring testing and setup needs of his Winston Cup engine building program. Since that time Hendrick Motorsports has used their PT-200 systems as their valve spring tester and setup system for multiple NASCAR Cup championship winning engine programs. The PT-200 has also gone on to become the premier valve spring tester used by most of the leading NASCAR Cup, Busch and NHRA Pro Stock engine builders (see customer list).       -Click Here to see a Video Demo of the PT-200 Valve Spring Tester-

Power Technology followed the PT-200 system with the PT-500 Chassis Spring Tester. As with the PT-200, we consulted with top chassis experts (including Indy car crew chief Larry Curry) to develop a system that met the critical needs of today's complex chassis setups. The resulting PT-500 tester is one of the few systems available that allows you to fully test and document your chassis spring setup in a matter of minutes.
