LS1/LS2 Oil Pan Bolt Kit 12pt.

The ARP LS1/LS2 Oil Pan Bolt Kit 12pt is a precision fastener upgrade engineered for builders and enthusiasts running GM LS-series engines. Whether you're assembling a stock rebuild or a high-horsepower stroker, this chromoly bolt kit replaces the factory oil pan fasteners with superior hardware designed to handle the demands of modern engine building. Oil pan bolts experience constant thermal cycling and vibration; factory hardware often loosens under aggressive driving or boost, risking oil leaks and catastrophic engine damage.

This kit features 12-point chromoly construction with black oxide finish, offering measurably higher tensile strength than OEM steel bolts while resisting corrosion and galling during installation and removal cycles. The 12-point head geometry distributes clamping load across more contact surfaces, reducing fastener stretch and improving repeatability in torque specs—critical for maintaining oil pan seal integrity under sustained boost or high-RPM operation. Chromoly's superior yield strength means these bolts maintain preload through temperature swings that would cause inferior fasteners to relax, preventing the micro-movements that lead to oil seepage at gasket interfaces.

Mechanics and engine builders working on LS1, LS2, and compatible LS-platform engines will appreciate the reliability upgrade this kit delivers—essential for turbocharged, supercharged, or nitrous applications where oil supply consistency is non-negotiable. The black oxide finish provides light corrosion protection suitable for engine bay environments, and the complete kit eliminates the need for sourcing individual bolts from disparate suppliers. Installation is straightforward: replace factory bolts one-for-one, torque to specification, and enjoy the confidence of factory-grade fastener engineering backed by ARP's reputation in motorsports.
