Jeep CJ7 LS Swap Headers for GM LS-Based Engine Conversions
Building an LS-powered Jeep CJ7 requires exhaust components designed around the unique space and routing challenges of an engine conversion. These Jeep CJ7 LSX swap headers are designed for custom CJ7 projects running popular GM LS-based engines including 4.8L, 5.3L, 6.0L, LS2 and LS3.
The system combines 304 stainless steel header tubing with heavy-duty 321 stainless steel flanges to create a durable performance exhaust solution for LS-swapped Jeep applications.
Designed for performance-oriented, off-road and custom builds, the header layout helps address the limited installation space encountered when fitting a GM LS-based engine into a Jeep CJ7 chassis.
Built for LS-Powered Jeep Projects
An LS engine conversion places different exhaust requirements on the CJ7 chassis than the original Jeep engine configuration. A properly designed swap header provides a cleaner starting point for routing the exhaust system while supporting the airflow requirements of the LS engine.
- Designed for Jeep CJ7 LS engine conversions
- Supports popular 4.8L, 5.3L and 6.0L LS-based engines
- LS2 and LS3 applications included
- Performance-oriented header and collector configuration
- Designed with custom swap installation clearance in mind
- Stainless steel construction for strength and heat resistance
- Heavy 12mm stainless steel flanges
- Intended for modified, custom and off-road Jeep projects
304 Stainless Steel Header Tubing
The header tubing is manufactured from 304 stainless steel with a 1.9mm wall thickness. Stainless steel provides the durability and heat resistance needed in a high-temperature exhaust environment while offering excellent material quality for a custom performance installation.
321 Stainless Steel 12mm Flanges
The headers utilize 321 stainless steel flanges measuring 12mm thick. The precision-cut flange design provides a substantial mounting surface and is engineered for durability in demanding LS swap applications.
LS Engine Applications
These headers are designed for Jeep CJ7 LSX swap projects using the following LS-based engine applications:
Engine swaps vary according to engine placement, mounts, transmission, steering, suspension and other modifications. Verify your individual build configuration before installation.
IMPORTANT - CUSTOM ENGINE SWAP APPLICATION
These are LS swap headers for modified Jeep CJ7 applications. An engine-swapped vehicle does not have one universal factory configuration.
Final fitment can vary depending on engine mounts, engine position, transmission choice, steering components, suspension configuration, exhaust routing and other modifications made to the vehicle.
O2 sensor extensions may be required.
Professional installation and fabrication experience are strongly recommended for custom engine conversion projects.
Off-Road Performance Application
This system is configured without catalytic converters and is intended for off-road/custom performance applications. Buyer is responsible for determining suitability and compliance with applicable local, state and federal requirements before installation or use.
