Not all piston rings are created equally. Total Seal’s Keith Jones helps us understand how material choice affects performance There is a reason why some piston rings go for forty bucks a set while others run 400 bucks a set. And in the right situation both are considered a good deal. That’s because rings for […]


It is hard to see between all the bars on a Late Model chassis, so we assembled the Jones Racing Products rear mount accessory drive kit on this bell housing and motor plate. This is an extremely sanitary, well-engineered setup for spinning the fuel pump, power steering pump and alternator.

Every car on the track may have to meet a minimum weight, but that doesn’t mean crafty racers can’t still find an advantage over the rest of the field.

In the real world racers have to make every buck count. The key is to find components that can give you optimum performance without an optimum price.
