S&S Cycle 36-84 BT 3-5/8in Piston Set - Standard

Flathead Power® Forged 3-5/8" Bore Stroker Pistons replace several cast and forged big bore pistons that S&S® previously offered. Applications for this piston include 88", 4-1/4" stroke, 93", 4-1/2" stroke, and 96", 4-5/8" stroke, engines with stock 8-1/2" diameter flywheels and 98", 4-3/4" stroke, and 103", 5" stroke, engines with 8-1/4" small diameter flywheels. As with the new stock bore stroker piston, the modern metallurgy and advanced skirt profiles allow a relatively close piston fit for low engine noise and long engine life.

Enhance the performance and longevity of your Harley Davidson touring motorcycle with the S&S Cycle 36-84 BT Forged 3-5/8 inch Bore Stroker Pistons. Designed as a direct replacement for several big bore piston options, these pistons are compatible with engines ranging from 88 inches with a 4-1/4 inch stroke to 103 inches with a 5 inch stroke. Their advanced metallurgy and optimized skirt profiles allow for a close piston fit, which helps minimize engine noise and promotes longer engine life, making them an excellent choice for both rebuilding and performance upgrades.
Constructed from forged materials, these pistons provide superior strength and durability under high-performance conditions. Their modern design ensures a snug fit within the cylinder, reducing unwanted vibrations and noise. Suitable for Harley Davidson FLT Tour Glide and FLHS Electra Glide Sport models from 1980 to 1984, they are engineered to meet the demands of power sports enthusiasts seeking reliable and efficient engine components.
Installation of these pistons requires acknowledgment of carburetor compatibility, as they are not carb-approved but are designed to work seamlessly with stock configurations. Their precise engineering ensures a proper fit and optimal performance, contributing to smoother power delivery and enhanced engine response. Whether you're restoring your classic bike or building a high-performance engine, these forged pistons are an essential upgrade for dependable, long-lasting power.
