The wheel CURES SURGE. There are other options for this, such as the ATS Compressor Housing. We sell both and have no reason to make false statements to push you in either direction. THEY BOTH WORK. It is possible that neither cure your surge 100% under extreme conditions. The only time we hear of 100% fix on trucks towing HUGE loads over max GVW or truck pulling has been using BOTH ITEMS. One or the other will cure surge most trucks 100% of the time. The wheel is cheaper and in most cases is all it takes to do the job. The ATS housing works also, but is more expensive and offers no other benefits over the wheel. PERSONAL CHOICE HERE. Choose one or the other. Only a small percentage of trucks will need both.
