LS Series Wiseco “Junkyard Dog” 5.3L Forged Piston Set 3.78″ Bore 3.622″ Stroke 6.098″ Rod Length .945″ Wrist Pins -10.7cc Dish

As the leader in LS-1 forged pistons, Wiseco pulled out all the stops when designing this series. Designed to accommodate the reluctor ring on stroker cranks without having to notch the pin bosses. Offset pins like O.E. and skirt shapes specifically designed for street applications make these the best pistons available.
