its the matrix wing mount assembley and a proline wing it mounted good but you only use the 2 lower screws on the wing mount i still need to run it. only installed it today still need the wing cross bars at the back of the wing. you know those 2 bars that are usually on all the buggy wings. i would say my truck weighs around 14 pounds know just guessing with the plastic driveline from the genesis should place me at the 12 pound mark
