Transmission Shop


Here at 4DHPClub, we LOVE to TORTURE OEM parts to find their weak points, and we certainly do not stop the torture tests at one of the most critical driveline components! We have put in extensive hours of research and testing to provide the best possible transmission upgrades to our customers.


Performance Packages


Here at 4DHPClub we offer several performance packages for GM LS & LT based platforms. Our packages range from 400 to 2,000+ Horsepower. We've poured endless hours into research and development to produce affordable combinations which we feel are very powerful, yet able to retain reliability and street-ability. There are several options and upgrades available, please know that we are happy to custom configure a performance package to suit your specific needs, so don't hesitate to contact us today to discuss your goals.
