  KB Rear Suspension Simulator

  Innovation on the Horizon

   by Tim Lee
Kent Billings is an unlikely guy to be developing products for the Dirt Late Model world. A Connecticut pavement racer with a small fabricating business that does contract work for entities such as the New York Transit Authority ("If it's a weird job, it usually finds me," he said.), Billings generally only sees dirt racing once a year, when he treks south to Florida for Speedweeks.

  But through his friendship with AFCO's Mark Bush, Billings has found himself more and more involved with the world of mud-slinging. And due to Bush's urgings, Billings has recently come up with the innovative KB Rear Suspension Simulator, a device that allows the user to attach a number value to the changes made on the rear suspension of a race car. Billings' invention emulates the linkage of a race car's rear suspension and shows the effect of changes made. Want to know how much moving the upper link an inch on a four-bar car effects other components? No problem, just remove the locking pin, move the linkage and study the results.

  "The Rear Suspension Simulator provides quick analysis of your rear suspension's link and shock positions, [as well as] actual measurements of the effects of adjustments made to your car's rear suspension," said Bush, who also teaches the RaceRite Dirt Track Chassis School. 

 

"It enables direct comparison between various suspension types and provides a clear understanding of rear suspension layouts and adjustments. It can be easily used, both in the shop and the track. It's an ideal tool for both racers and chassis builders."

  According to Billings, Bush had been after him for a while to produce such an item. "Mark kept on about something that  would allow us to look at  everything [on the rear suspension]," Billings said. "Eventually, I did the work and figured out how to make it happen."

  Billings only planned to make one Simulator. "I was going to build one for [Bush} personally to use as a teaching aid, as a kind of a gift," he said. "Along the way the way, Mark got more excited that this might happen and talked to some guys and found out there was interest in something like this.

  "Now hopefully, we can market the thing and it can help some people out."

  Even before the Rear Suspension Simulator has hit the market, the chassis builders who have seen the prototype are excited. Larry Shaw Race Cars and Mark Richard's Rocket Chassis company are already lined up as distributors for the Simulator, which is expected to be available in late February.

  Bush for one, is pleased with the final result. "I think it [the Simulator does everything I originally hoped it would do," he said. "It makes analysis work so much easier. I used to have to draw things out and that takes time. With this, you see the results immediately."

   "I think there's a benefit to seeing where everything moves. That's not something you can do on paper."

  So maybe Billings isn't such an unlikely candidate for Dirt Late Model innovation. "I have a small fabricating business and I love racing, been involved for 25 years," said the burly New Englander. "I love the challenge of figuring out how to make things that haven't been made."

  And he's found plenty of food for thought since he's been around Bush's schools and Late Model cars. The past few years, Billings has been "going to these seminars and talking to people and listening to their problems. I'm always curious about what their big problems are."

  Billing's latest project, which he hopes to complete this year, is a new birdcage design featuring internal bearings and seals to keep dirt out and prevent binding. These guys have been telling me that they clean their birdcages to keep the dirt out," he said. "It seemed to me that it would be better to start on the other end and keep the dirt out in the first place."

  Further development work on Dirt Late Model pieces are currently on hold, pending the success of the Rear Suspension Simulator. But with Billings' natural curiosity, and the input of Late Model movers and shakers such as Bush, Richards and Shaw, look for this Connecticut Yankee to make more headlines in the Dirt Late Model court.
