Gold Level Sponsors

This level is our highest level of non-Cadillac dealership sponsors.  These sponsors are committed to the success of the Cadillac V-Club and have made a financial commitment and assigned up to 5 of their employees as members of the V-Club to actively participate at events and activities.  They frequently offer special promotions available only to V-Club members and are well recognized as premier product and service providers in the industry.

We take the guesswork out of all fabrication processes with 5 different in-house CNC machines. When you have the best tools, you let the tool do the work!

Some factory heads are better than others, but none are better than ours. We specialize in late model muscle. Got a bigger build in mind? We also CNC port the popular aftermarket heads. Learn more about our CNC ported cylinder heads.

We heavily modify cast/fabricated manifolds to create exactly what you want.

Custom Performance Calibration

When your goal is to maximize WOT torque/horsepower output, while also optimizing drivability and part throttle characteristics, 4DHPClub offers fully customized calibration & tuning services by one of the best in the industry, Justin White Tuned. This service includes use of our in house 3,000+ horsepower Mainline ProHub dyno. This type of dyno bolts directly to your axles, giving much better information, allowing tuners the opportunity to fine tune high horsepower cars which are prone to spinning their wheels on conventional chassis roller dynos.

Whether you are a first time customer or a repeat customer, becoming a 4DHPClub website member will ensure you always receive preferred support  on all calibration services.  In addition, we are offering special pre-configured performance upgrade packages which you may optionally purchase as a member of the team via our online catalog.

Our Specialties

We are a manufacturer of aftermarket motor vehicle engine mounts and suspension parts. We design, manufacture and offer engine mounts to the automotive community that fill the void between low quality, factory installed engine mounts and the aftermarket mounts that the major manufactures fail to offer. Interestingly, the major manufactures are the ones that supplied the OEM car companies with the mount that failed in the first place.
