3mirrors LS exhaust manifold bolt repair kit — Driver front / Passenger rear, TIG‑welded steel clamps & replacement fasteners

3mirrors LS exhaust manifold bolt repair kit is a bolt-and-bracket solution that restores a broken or seized exhaust manifold stud without removing the cylinder head.

If an LS-series engine in your Camaro, Corvette, GTO, CTS‑V or GM truck has a stripped or snapped exhaust manifold stud, this repair kit gives a quicker, lower-cost alternative to head removal. The kit supplies welded steel repair brackets, replacement fasteners and washers designed to clamp the manifold securely and stop leaks and rattles caused by broken studs. It’s engineered for a range of GM small-block V8s and offers a serviceable repair that mechanics and experienced DIYers can install with common tools.

How does this kit fix a broken exhaust manifold stud without pulling the head?

The 3mirrors repair brackets bolt to the existing manifold and cylinder head area to clamp the manifold flange tightly. The welded steel blocks provide new anchor points that take the load normally carried by the original stud, sealing the exhaust port and stopping vibration.

• Uses heavy-gauge TIG‑welded steel blocks to replace the lost stud function
• Includes matched bolts, washers and mounting hardware for a secure clamp
• Designed to compress the flange and restore the gasket seal without head removal
