When Ford started making the new S550 Mustangs, they used flimsy and breakable materials for their factory reverse lock-out collar. Because of this, over time, your OE reverse lock-out collar will probably break. This is more than just a minor annoyance: if this part breaks, you won't be able to put your 2015-2022 Mustang in reverse! Make sure this doesn't happen to you by picking up this new Steeda Delrin Reverse Lock-Out Collar, now available from CJ Pony Parts!
