When it comes to your Chevy LS engine, every detail matters. Header bolts that work loose can lead to exhaust leaks, lost performance, and potential damage to your expensive headers. That's why ARP has been the trusted name in high-performance fastening solutions for decades.
Factory header bolts often lack the strength and precision needed for serious performance applications. They can stretch under heat cycles, vibrate loose over time, or simply corrode away, leaving you with costly repairs and potential engine bay damage. You need fasteners that can handle the demands of high-temperature operation while maintaining their grip.
This ARP Header Bolt Kit (P/N 134-1102) is specifically engineered for GM LS-Series engines, ensuring perfect fit and performance. The 3/8in flange hex design provides excellent clamping force while being easy to install in tight engine bay spaces. Each bolt is manufactured from premium materials and heat-treated for maximum durability and resistance to the extreme temperatures found under the hood.
Whether you're building a new engine or replacing worn-out header bolts, this kit includes all the hardware you need for a professional installation. The flange hex design allows for easy tightening with standard tools, and the precise thread engagement ensures a secure connection that won't back out under vibration.
Performance enthusiasts and professional mechanics choose ARP for good reason. These bolts have been track-tested and proven to maintain their clamping force through countless heat cycles. Whether you're running on the street, at the track, or towing heavy loads, you can count on ARP fasteners to keep everything exactly where it should be.
Don't leave your header installation to chance. Give your Chevy LS engine the professional-grade fastening it deserves with ARP's proven header bolt kit. It's the small detail that makes a big difference in performance and reliability.
