| SKU | 28202400 |
| Application | 1967-1987 Chevrolet / GMC trucks with stock-port 23-degree small-block Chevrolet engine |
| Header primary diameter | 1-7/8-inch |
| Collector diameter | 3-inch |
| Drivetrain | 2WD / 4WD; automatic / manual |
| Collector design | Venturi collectors |
| Clutch linkage | Expected to work with most Z-bar manual setups; check the actual linkage and engine position before ordering |
| Material | 304 stainless steel |
| Configuration | 28202400; Header Size: 1-7/8" |
The sound and character of a small-block are a big part of owning a classic Chevrolet or GMC truck. These Kooks 304 stainless headers give your exhaust a purpose-made starting point, with 1-7/8-inch primaries and 3-inch collectors.
SKU: 28202400
28202400 is designed around stock-port, 23-degree small-block Chevrolet heads in the 1967-1987 truck application. It covers 2WD and 4WD, automatic and manual installations, and is expected to work with most factory Z-bar clutch linkage.
The 3-inch Venturi collectors join the primaries to your connecting exhaust. Choose the primary size around your engine, then have your installer check clutch linkage and chassis clearance on the finished truck.
We recommend tuning with every header installation so the calibration suits your headers, complete exhaust and fuel. Talk to us to discuss tuning for your vehicle and the parts you are fitting.
For the same stock-port 23-degree small-block installation in a 1967-1987 Chevrolet / GMC truck, compare the 1-3/4-inch truck headers before choosing your primary size.
