JB Performance brings you quality, performance and reliability with our line of billet impeller wheels.

Exact fit improved JB Performance billet aluminum impeller is a direct fit replacement clockwise impeller wheel. JB Performance 3.1" billet wheels are professionally designed to replace cast OEM Vortech Si and Sci trim, as well as Paxton 1200, 1220, 1200sl, and 1220sl style impellers. The blades must curve in a clockwise pattern.

Our impellers are professionally designed by air flow engineers that already design turbo wheels. These wheels are professionally 5 axis machined and zero balanced on a CNC for a precise build quality. After machining, they are crack checked for defects with an x-ray, then anodized and logo etched for a perfect wheel that almost looks like art!

Direct fit for the following Vortech and Paxton Superchargers:

• Vortech V1 Si or Sci trim, Generation 1 or 2.
• Vortech V2 Si or Sci trim, Generation 1 or 2.
• Vortech V3 Si or Sci trim, oil injected or self contained.
• Paxton Novi 1200, 1220 later style. Recommend measuring inducer size to be sure. Two types were used.
• Paxton Novi 1200sl, 1220sl later style. Recommend measuring inducer size to be sure. Two types were used.

If you are unsure of your fitment, measure the inducer (intake) side of the impeller blade diameter. It should be right around 3.07" or 78mm.
