If your 1953 or 1954 Chevy just doesn't get the performance you expect from your original 6 cylinder engine maybe the vacuum advance is bad! The original vacuum advance has a rubber internal diaphragm that can dry rot and crack after 50 plus years of use. A defective vacuum advance will prevent the timing from advancing properly and will cause sluggish throttle response. This brand new vacuum advance from Eckler's Early Chevy includes a new inner diaphragm good for another 50 years! Pep up your classic's performance with one of our new vacuum advances. Our vacuum advance fits 1953 or 1954 Chevrolet Bel Air, 210 and 150 with 6 cylinder engines.
