AIFF 2PCS M10x1.25 Exhaust Manifold Bolts Kit Spring Loaded Flange Hardware

Exhaust leaks often start with bolts that lose clamping force after repeated heat cycles and engine vibration. When the flange connection becomes loose, you may notice ticking sounds, exhaust odor, or reduced sealing performance. This AIFF exhaust manifold bolt kit uses a spring-loaded design to maintain consistent pressure while compensating for thermal expansion and engine movement. Each component is made from alloy steel with a zinc-plated finish for improved corrosion resistance in harsh under-vehicle conditions. The package includes two complete repair sets, and each set contains one bolt, one spring, one nut, and one washer for a total of eight components. Ideal for exhaust manifold, flange, and gasket replacement repairs. Always verify thread size and measurements before installation.

• 【Spring Loaded】Built-in springs maintain consistent clamping force and compensate for heat expansion and contraction during exhaust cycles. This helps keep manifold gaskets compressed properly and reduces the risk of leaks caused by loose hardware over time
• 【Vibration Control】Engine movement can gradually reduce bolt tension during daily driving. The spring mechanism absorbs vibration changes and provides additional support to the flange connection, helping keep exhaust hardware secure for long-term us
• 【Heat Resistant】Made from alloy steel with a zinc-plated finish, these exhaust bolts are designed for harsh underbody conditions. The durable construction helps resist corrosion from moisture, road salt, and repeated high-temperature exposure near the exhaust system
• 【Exact Fits】Designed with M10x1.25 threads, 68mm overall length, 9.7mm stud diameter, and 40mm threaded section. Check your original hardware measurements before ordering to confirm proper compatibility with your exhaust flange application
• 【Complete Sets】Includes two complete repair assemblies with bolts, springs, nuts, and washers. Eight total components provide the matching hardware needed for exhaust gasket replacement and flange repair projects without searching for extra parts
