234120 Fits Shovelhead 1978 1984 1340CC 80CI 9 5 1 Compression Pist

These Wiseco forged piston kits are a top-tier choice for Knucklehead, Panhead, and Shovelhead engines, offering significantly more strength than standard cast pistons. One of the best things about these is the tight clearance; they can be set up at .0025 to .0035 inches, which keeps the top end much quieter than other forged options that need more room to expand. They are also about 60 grams lighter than factory units, which helps the motor rev quicker and takes some of the load off your connecting rods. Each kit is sold as a set for two cylinders and comes complete with Hastings X-style rings, wrist pins, and circlips. They fit a wide range of Big Twin models including FX, FXR, Softail, and Touring bikes.
