Ceramic Coated LS Swap Long Tube Headers for 1973–1987 Chevy GMC C10 K10 Square Body Trucks and 1988–1991 Blazer Jimmy Suburban 2WD 4WD with MLS Gaskets by Certified Automotive Experts — Open-Box, 12% Off

CERAMIC COATED PERFORMANCE: High-temperature ceramic coating helps manage exhaust heat, protect surrounding components, and maintain consistent performance under sustained load in street, towing, and performance LS swap applications.

LS SWAP LONG TUBE DESIGN: Full-length long tube header configuration with 1-3/4 inch mandrel-bent primaries and 3-inch merge collectors designed to improve exhaust scavenging, torque delivery, and overall engine response.

PROVEN FITMENT ON SQUARE BODY CHASSIS: Engineered specifically for LS swaps in 1973–1987 Chevrolet and GMC C/K pickups and 1988–1991 square-body Blazer, Jimmy, and Suburban platforms using the classic square-body frame design.

HEAVY-DUTY CONSTRUCTION: Built from thick-wall steel tubing with CNC-machined 3/8 inch flanges and precision TIG-welded joints to resist warping, leaks, and long-term fatigue in real-world driving conditions.

INSTALLATION AND TRANSMISSION NOTES: Compatible with LS-series engines including 4.8L, 5.3L, 5.7L (LS1), 6.0L, and 6.2L. Hydraulic clutch manual transmissions such as NV4500 have been verified. Mechanical clutch linkage setups may interfere. Large-case transmissions like TH400 and 4L80E may require minor bellhousing or dust cover trimming for proper clearance.

"The CAE-032-C ceramic coated long tube headers are built specifically for LS swap installations where real-world fitment, clearance, and durability matter more than generic catalog claims. This version uses the updated CAE-032 routing geometry refined through hands-on square body installs. The long tube configuration features 1-3/4 inch mandrel-bent primary tubes feeding into formed 3 inch merge collectors. Compared to restrictive factory manifolds, this layout improves exhaust scavenging, supports stronger mid-range torque, and enhances throttle response across the powerband. A high-temperature ceramic coating acts as a thermal barrier to help control radiant heat and protect nearby chassis and drivetrain components. This finish is particularly beneficial for daily-driven LS swaps, tow rigs, and performance street builds where sustained heat management is critical. Construction emphasizes structural integrity and sealing reliability. Thick-wall steel tubing, CNC-machined 3/8 inch flanges, and precision TIG welds help maintain gasket seal and reduce the likelihood of warping or fatigue over time. O₂ sensor bungs are pre-installed on both headers for straightforward integration. These headers are designed for LS-series engine swap applications only and are not compatible with factory LS-equipped vehicles, Gen V LT engines, SBC engines, or BBC engines. FITMENT APPLICATIONS 1973–1987 Chevrolet and GMC C/K pickup trucks 1988–1991 square-body Blazer, Jimmy, and Suburban Designed for both 2WD and 4WD configurations when properly mounted for LS swap installation. NOT COMPATIBLE WITH OBS or GMT400 pickups 1988–1998 Gen V LT engines SBC or BBC engines Factory LS-equipped platforms TRANSMISSION NOTES Hydraulic clutch manual transmissions such as NV4500 have been successfully installed. Mechanical clutch linkage systems may experience interference due to tight routing. Large-case transmissions including TH400 and 4L80E may require minor trimming of bellhousing ears or dust covers, consistent with common LS swap practices. Due to header routing, factory spark plug wires and factory heat shields are not compatible. Aftermarket LS swap spark plug wires are recommended. Engine placement and crossmember selection affect final clearance and should be reviewed before installation."
