Product Description

The JBA 1840S Shorty Headers are performance exhaust headers designed for 1988-1995 Chevrolet and GMC full-size C/K trucks equipped with the 4.3 L V6 engine without air injection. These headers drastically improve exhaust flow and throttle response compared to stock manifolds thanks to mandrel-bent 1.5" primary tubes and JBA's Firecone® collector design. This setup reduces backpressure, enhances horsepower and torque in the low to mid-RPM range, and maintains emissions compliance in most states.

Constructed from high-quality 409 stainless steel with thick CNC-machined flanges, the 1840S headers offer excellent durability and long service life even under regular towing or daily driving. The included hardware and gaskets make installation straightforward for experienced DIYers and professional mechanics alike. These headers are a popular upgrade choice for enthusiasts seeking improved performance without the footprint or cost of long-tube headers.
