Not everybody is after massive power numbers. Oftentimes you just need a mild bolt in upgrade that will make your 12 valve or 24 valve truck keep up with the newer diesels on the road. The billet 6 blade 62mm HX35 upgrade is perfect for this. It utilizes a 62mm billet compressor for more airflow and it is coupled with a 64mm turbine wheel to help keep exhaust temps and exhaust pressure down. All of this is done without sacrificing spool up time. This upgrade is good for 400+hp and is a direct bolt in for nearly all 2nd generation dodge trucks.
