This is a pair of Rock Shooter 1.9" Aluminum Composite Internal Bead-Loc Wheels. These Rock Shooter wheels are designed to not only look scale with the 12 hole design but to be super easy to use by only requiring 6 screws per wheel for mounting tires. The face of the Rock Shooter has been CNC machined in the USA to exacting tolerances and precision finishes that are second to none! These look just like real wheels! The unique 3-piece wheel design bolts together in the back and locks on to Pro-Line's incredible list of 1.9" crawling tires the same way as Pro-Line's Impulse 1.9" plastic wheel. The overall wheel width and wheel offset are the same as Pro-Line's Impulse 1.9" plastic Wheels, so you know they will fit your truck and look good doing it.
