The Solid Rocket is available in Full Machined or Full As Cast finish. Add our Custom RPM7 powder coat to replicate the classic, magnesium DOW7 finish of the 1960's. Each Solid Rocket wheel is precision-crafted from A356 aluminum. The Rocket Fire and Solid are both 5-Lug Bolt-on wheels and utilize conical seat open end lugs. Run them with or without our optional Painted or Polished Lug Covers and Vintage Knockoffs. As priced below, the Fire and Solid wheel series do not include any center cap. However, we have designed the wheel to accept Bullet Caps, Rocket Dome Caps, Lug Covers and Knockoffs or Knockoffs only.
