SOLID ROLLER<br />
TD, TJ & TJS SERIES ROLLERS<br />
The TD designs are excellent for high ratio, four barrel 390 carb rules such as NASCAR Busch and Craftsman Truck<br />
Series applications. The TJ's have slightly more lift but are a little smoother. The TJS's are basically the same as<br />
the TJ's except for a slightly softer closing ramp.<br />
