Performance Headers for Chevy GMC C10 C1500 2WD (1992-1999) 4L 5L 6.0L Engines

Stop fighting with clearance issues and fabricating custom pipes. Drop that modern LS V8 into your classic GM chassis with headers engineered specifically to clear your frame rails and crossmembers.

Stainless Steel LS Swap Long Tube Headers for Chevy C10, C1500 & 2WD GM Trucks

The LS swap is the ultimate upgrade for classic Chevy trucks, but getting a Gen III or Gen IV V8 to fit between the frame rails of a C10 or OBS (Old Body Style) truck often turns into a nightmare of clearance issues. Factory manifolds are restrictive and ugly, while generic "universal" headers often hit the steering shaft or crossmember. These T304 Stainless Steel Long Tube Headers are the solution. Designed with specific geometry to accommodate the 2WD C-Series and GMT400 chassis, they provide the necessary clearance when used with the correct motor mounts, eliminating the need to hammer tubes or cut frames.

Your LS engine is an air pump, and the "log" style manifolds found on stock truck engines (4.8L, 5.3L, 6.0L) are a major bottleneck. These headers feature mandrel-bent 1-3/4" primary tubes that allow the engine to exhale freely, supporting massive power gains. In fact, dyno testing has shown gains of over 22 rear-wheel horsepower just by bolting these on. The 3" collectors feature internal merge spikes—a race-spec detail that smooths out exhaust turbulence and maximizes scavenging velocity, ensuring crisp throttle response and a broad torque curve.

Budget headers usually mean rusty mild steel headers in six months. These are constructed from polished 304 stainless steel, offering superior thermal resistance and corrosion protection. Whether you are building a patina C10 shop truck, a lowered C1500 sport truck, or a 2WD Blazer, these headers provide the high-end look and performance durability your build demands.

Why You Need This Upgrade

• Swap-Specific Geometry: Engineered to solve the notorious steering shaft and crossmember clearance issues on 2WD C10 and C1500 LS swaps.
• Dyno-Proven Power: Uncorks the exhaust flow to deliver gains of 22+ RWHP compared to restrictive factory cast iron manifolds.
• Race-Spec Collectors: Features 3" collectors with internal merge spikes to reduce turbulence and increase exhaust gas velocity.
• Premium Durability: TIG-welded 304 Stainless Steel construction resists heat discoloration and rust far better than chrome or mild steel.
• Optimized Primaries: 1-3/4" primary tubes provide the perfect balance of low-end torque and high-RPM breathing for 4.8L, 5.3L, and 6.0L engines.

Installation Notes

Professional Installation Highly Recommended. These are custom swap components.
Critical Motor Mount Requirements:
• 1988-1998 C1500/OBS Trucks: Requires 1" Offset Back Motor Mounts to clear headers.
• 1960-1966 C10 Trucks: Requires slider engine mounts to clear the front crossmember.
Drivetrain Note: Fits 2WD models ONLY. Does NOT fit 4WD (K-Series) trucks due to front driveshaft interference.
Gaskets: Includes standard graphite manifold gaskets.
