About This Product
For high-output 5-speed Big Twin builds, the stock transmission trap door can often be a weak point. This Alu-Tec billet aluminum trap door from Zodiac is CNC-machined from solid aircraft-quality aluminum to incredibly tight tolerances. It is designed to be strong enough for engines pushing over 100 horsepower while remaining economically priced. It is a direct replacement for OEM 35250-90B and is fully compatible with your stock bearings, retaining rings, and transmission end cover. This is a smart upgrade for Dyna, FXR, Softail, and Touring models, providing the structural integrity needed to keep your gear sets properly aligned under heavy load and high-performance conditions.
