15 Series Gas Shock
Updated: Jul 22, 2021
The 15 Series shock came into play after we won the NeSmith Street Stock Championship the first time on 20 Series shocks and a rule change required a smooth body shock. As we always do it is a honed body shock with a treated ID surface that will produce a valving that will not fade over the course of a season of racing. This is a full size shock that comes in a 7 inch and a 9 inch and has the coil-over rings cut into the body, this shock will be the Official Shock of the NeSmith Late Model Sportsman class that will start in the 2017 race season. We built a really cool coil-over kit that fits this shock for a 2.5 inch spring. For a shock that has the feel and performance you need and stays inside the rules package this is it, whether your back east or down south this is the shock for you. Here are some other fine points about the 15 Series shock. (Note we have won the Nesmith Stock Car National Points Championship 5 times and the UMP B-Pro mod 4 time)
Low drag assembly, which includes the divider, seal and main piston.
Bronze coated Teflon wearband, reduces friction and increase sealing.
Honed and coated tube ID.
High flow linear piston design.
Ring grooves cut for coil over kits.
Shocks can be valved in any configuration or in standard valving, also see Shock We Build to get a better understanding of the shocks we build.
Standard builds would be 4040 which is a 4 rebound and a 4 compression, see valving chart to see pressures at 10 inch per second.
Custom builds will be more like RF1-50 +130
