Stainless Steel LS Header Stud Kit,M8 Exhaust Manifold Studs Fit Chevy Gen3 Gen4 LSX LS1 LS2 LS3 LS6 LS7 4.8 5.3 6.0 6.2L Vortec Truck Engines

LS Header Stud Kit is a premium aftermarket exhaust hardware upgrade designed to replace weak factory exhaust bolts for all Gen III & Gen IV LSX Chevrolet V8 engines, covering passenger cars and Vortec truck motors with 4.8L, 5.3L, 6.0L and 6.2L displacements. Made of hardened polished 304 stainless steel, these M8 exhaust studs and matching locking flange nuts stand up to extreme exhaust heat cycles, road salt and long-term grease exposure. Unlike stock carbon steel bolts that easily rust, seize or snap during disassembly, stainless steel construction ensures long service life and hassle-free future exhaust gasket maintenance.The biggest upgrade over OEM single-use bolts is the stud mounting design: Thread all studs firmly into cylinder heads first, then slide your exhaust manifold or long tube header over the studs and secure with locking flange nuts. This removes the frustrating struggle of holding heavy manifolds while lining up tiny bolts, cutting exhaust installation time in half and preventing gasket misalignment & exhaust leaks.Each complete set comes with 12 M8 polished studs and 12 hex locking flange nuts, fully machined to original factory dimensions. The studs work with standard #4 Allen key sockets for quick torque adjustment, fitting perfectly on stock OEM exhaust manifolds and all popular aftermarket performance headers for LS engines.This exhaust stud hardware kit is a must-have for LS engine rebuilds, header upgrade projects, leak repair and spare roadside repair kits. Compatible with GM Silverado, Sierra, Yukon, Camaro SS and custom LS-swap hot rods, restomods and track vehicles.Tip: Apply anti-seize compound on stud threads before installation to further prevent rust and seizing for easy future removal.
