Throughout the 2017 season ARS has been running a double bump package for the right front of a dirt late model. This package helps control the compression with a soft foam bump and a stiff urethane bump. This allows the right front to compress easy on the foam at the same time still maintaining enough rate with the urethane bump at the bottom of your travel.
1- 600429 1 1/8” foam bump rubber
