This shift knob is the right fit for 2015-2017 FCA cars that have standard shift with reverse lockout. I believe the Dodge Dart, Fiat 500 Abarth, and Jeep Renegade (6-speed) all use such a knob. There are very few knobs available that have the right size collar to permit the lockout to fit underneath. This one is nice because it has a leather textured ball and is smaller than the factory knob (which is nice but big). It's a snap to install on these cars - snap the shift pattern insert off (a thin blade inserts easily under the insert) and unscrew the bolt underneath with a 10mm socket. Pull the knob off. This new knob has two sizes of coil inserts to take up any space - for these cars, use the larger coil. The included allen screw and wrench are used to secure the knob to the gearshift lever.
Nicely made, heavy, quality knob.
