OC Shocks, 281 Wall St., has added motorcycle tire sales and tune-ups to its product line.
"With there being a moto-cross track just outside of town, we're heavily involved in that," said owner Nick Silardi.
Silardi, who races dirt bikes, said he opened the business a little more than five years ago in Fremont and moved it to his hometown of Tiffin two years later.
The business started by specializing in repair and service of performance shocks for race cars, and now serves quad four-wheelers, snowmobiles, draf racing cars, road race cars and oval track cars.
"Not like on mini-vans. We don't do that kind of thing," he said.
"The bulk of our business is race cars from Attica and Fremont but we sell and service shocks for race cars all over the country," Silardi said. "Just today I sold shocks to New York, Missouri and Texas."
He said car owners choose OC Shocks "because of the service and the technical knowledge we have to make their cars go fast. Everybody wants to go fast."
Silardi said his company makes improvements to shocks made by other
"We don't manufacture it," he said. "We make it better."
