This is the Undercover LIGHTWEIGHT Flat Ladder Bar. We married the tried and true flat bar design with the popular ladder bar design to bring the best of both worlds. This bar is designed specifically for the DR10M car. It also doubles as a spacer shim, raising the trans and the C and D blocks up together. Comes with adjustment rod and hardware. Uses the stock wheelie wheel or just about any aftermarket wheel that is on the market today.
