The 2021 USAC AMSOIL Sprint Car National Championship schedule is highlighted by, not just one, but two trips to the east in the coming season, first in April, then again with the 14^th edition of Eastern Storm in the month of June.

The foray to PA April 22-25 is new to the calendar, and will thus, have a new name that will christen the four-race weekend which will all be held within the confines of the state of Pennsylvania – “Keystone Invasion.”

Keystone Invasion will feature the series on April 22 at Bechtelsville’s Grandview Speedway, on April 23 at Pottsville’s Big Diamond Speedway, on April 24 at York Haven’s BAPS Motor Speedway and concluding on April 25 at Spring Run’s Path Valley Speedway Park.
