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

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.
