The GM LT Block Hugger Sanderson Headers are the only true block hugger headers on the market designed specifically for LT-based engines. Engineered with 1-5/8″ primary tubes for improved exhaust flow and power, these Sanderson shorty headers are designed to hug the block tightly, allowing them to fit into applications where space is extremely limited. Each header features 3/8″ thick flanges, precision ground flat to ensure a secure, leak-free seal. The raw steel finish allows you to customize coating options to match your build.

Optional Upgrade: Professionally TIG welded V-bands available for easier maintenance and a cleaner, leak-free exhaust system.
