Lock Down Your Honda 1.5L L15 Bottom End with ARP Main Studs (108-5401)

• These are main stud replacements, and not head studs. 

If you’re pushing boost, revs, or hard track miles, the factory main fasteners can become the weak link. The ARP Main Stud Kit for Honda 1.5L L15 (Part #108-5401) is built to deliver greater clamping force, a more consistent main cap hold-down, and the confidence you want when the engine is under real load.

Whether you’re building a reliable daily driver with headroom, a street/strip setup, or a dedicated race engine, ARP main studs help support bottom-end sealing and stability—so your power stays consistent and your maintenance surprises stay minimal.

Why enthusiasts and builders choose ARP main studs
Main studs are designed to provide a more precise, repeatable clamping load than typical bolts—exactly what matters when cylinder pressures rise and tolerances get tight. This kit is engineered specifically for the Honda 1.5L L15 4-cylinder engine for fitment you can trust during assembly.

Best for: boosted builds, high-RPM setups, track use, engine refreshes, and “do it once, do it right” bottom-end builds.
