AfterBurner Performance

AfterBurner Performance Racing Community The shock service portion of the business will continue under the new company as well.

In December 2023, we rebranded our company to AfterBurner Performance as the Accu-Force Spring Smasher product line and name was acquired by DRP Performance Products in Bassett, VA. Our newly branded company will continue to be based in Millersburg, OH under Keith Berner's ownership and will offer the Torsion Bar Dyno, High-Torque Shock Dyno, and Fill Machine to customers. Consulting, chassis set

up, on track testing with data acquisition, and chassis analysis through its pull-down rig, will also continue to be offered through AfterBurner Performance. Keith had a successful 40-year racing career in the dirt late model world, retiring in 2014. Adding to that experience, Keith served as car chief in Nascar for the Butch Mock Motorsports #75 team. Surrounded by a team of employees with experience in racing, AfterBurner Performance strives to provide the best customer service possible at an affordable price.

We will be at Port Royal Speedway this weekend for the Lucas Oil Late Model Dirt Series. We always look forward to the racing there.

We decided to drive over a couple days early and delivered some new shocks to Cory Lawler Racing at the Pancho's Racing Products shop. We appreciate their ongoing business with us.

From carnage at Florence Speedway this past weekend to Wednesday night, Dillon McCowan and Riley Duncan have worked long hours to get a car ready for the next Lucas Oil Late Model Dirt Series race this weekend. We were happy to have them in our shop Wednesday.

While the guys from the JFR Motorsports/ Drake Troutman race team were busy working on the cars this week, Deb and our great niece Ellie, introduced Carson King to Amish country, stopping at an Amish school while traveling down many country roads.

The following day Carson joined Deb and a friend at a Cleveland Guardians game at Progressive Field. While Carson enjoyed the game, she also stayed busy writing social media posts for the team, checking on shirt orders, and making plans to help the team going forward, all from her game seat. 🏁

We enjoyed having the entire JFR Motorsports and Drake Troutman Racing team in our AfterBurner Performance shop this week. We ended the week with on track testing prior to them departing late Thursday night for Selinsgrove Speedway.

We wish the team the best of luck as they kick-off this adventure together.
Thanks to Jerry Foster, Drake Troutman, Hunter, Tom, Walmart and Carson for spending the time with us.

The transformation at Mansfield Speedway from one year ago to today is something to see.

In May 2025, we stopped in to show friends from Australia what remained of the Speedway. It was a neglected mess. A few days later we read the announcement that it was sold & going to come back to life. Indeed it did!

Getting ready to watch the World of Outlaws Late Model Series race tonight.
