EMPI Deluxe GT-1 Camshaft Kit — Cam, Lifters & Gear | VW Type 1, 2 & 3 (77-3104-0)

EMPI takes the guesswork out of matching a cam to its lifters and gear. The Deluxe GT-1 Camshaft Kit (77-3104-0) bundles the GT-1 profile with the exact lifters, gear, and hardware it was designed to run with — so your build or rebuild goes together right the first time.

Vehicle Fitment

• Confirmed: VW air-cooled Type 1, Type 2 (pre-1971), and Type 3 engines, 1200-1600cc — Beetle, Super Beetle, Karmann Ghia, Bus (pre-71), Type 3, Thing, Buggy, Baja.

• Not Confirmed: 1971-and-later Type 2 and Type 4 / 914 (different cam/case), and engines needing a stock-replacement-only profile.

• Break-In: Use a ZDDP oil or additive on break-in, as with any flat-tappet cam. Higher GT-1 profiles benefit from matching carburetion, springs, and rockers.

Why Choose EMPI?

EMPI matches each cam to the exact lifters and gear it was designed to run with, taking the guesswork out of a top-end build and helping it go together right the first time.
