The Rocket Booster 1 pc wheel was purpose built to deliver big style and performance for the finest muscle cars, pro-touring and street machines at very affordable prices. The Rocket Booster is precision-crafted from A356 aluminum and topped off with a vintage style aluminum o-ring center cap.   The Rocket Booster features a reverse mount soft lip outer that provides a longer spoke and maximizes the wheel window and better displays your performance brakes. The ultimate result is that your ride will get noticed at the next cruise-in or car show.

  • Classic styling
  • Available in Chrome, Gray and Hyper Shot Finish
  • 3.00" hub clearance under center cap
  • Screw-in center cap included
  • Lug nuts sold separately (requires 60 degree conical seat)


Available Finishes:

  • CHR (Full Chrome) - Fully chrome plated centers & rims
  • GRY (Gray Painted) - Gray painted center (color similar to as-cast aluminum) with a machined outer lip
  • SHOT (Hyper Shot) - Darker matte-finish center with a machined outer lip
Some parts are not legal for use in California or other states with similar laws/regulations
