Automotive ARP 150-3102 Black Oxide Hex Motor Mount Bolt Kit

Description

Product Overview

Engine builders and performance enthusiasts know that the foundation of a reliable powerplant starts with the bolts that hold the crankshaft, oil pump, and other critical components in place. The Automotive ARP 150-3102 Black Oxide Hex Motor Mount Bolt Kit delivers that foundation with a combination of premium materials, precise engineering, and thoughtful design. Each bolt is forged from chrome‑moly steel and finished with a black oxide coating that resists corrosion while providing a distinctive, low‑glare appearance. Rated at an impressive 170,000 psi, these bolts exceed the strength of typical Grade 8 hardware, giving you confidence that the engine’s mounting points will stay secure under the most demanding conditions. The kit includes all necessary flat washers, ensuring proper load distribution and eliminating the need for additional purchases.

Usage

Designed for a wide range of automotive applications, this bolt kit is ideal for both street‑driven vehicles and track‑focused builds. Whether you are reinstalling a rebuilt engine, upgrading to a high‑performance crankshaft, or simply replacing worn mounting hardware, the ARP 150-3102 kit provides a straightforward solution. The conventional hex‑style heads fit standard 12‑mm and 13‑mm sockets, allowing for quick installation with common hand tools. The black oxide finish not only looks professional but also helps reduce the risk of galling when paired with matching ARP nuts. Because the kit includes flat washers, you can achieve a uniform clamping force across the mounting surface, which is essential for maintaining proper engine alignment and minimizing vibration.
