10 nights since freshened and approximately 20 nights old total. Valved for a Bob Pierce Dirt Modified. There are no valving numbers just serial numbers from Advanced. These were Bob Pierce specific valving. Great condition overall, some small dings from rocks but typical used stuff.These were taken off after every race night, cleaned and lightly oiled. The heims, seals and shafts are in good condition and could be bolted on and used as is. The left rear shock has a extension. They would make a great set for a Pierce or any other dirt modified in general.
