ARP 147-2501 Balancer Bolt Kit High Strength Engine Main Bolts

Description

Product Overview

The ARP 147-2501 Balancer Bolt Kit is engineered for enthusiasts who demand uncompromising strength and reliability in their engine assemblies. Each bolt is forged from a high‑grade alloy that meets ARP’s stringent quality standards, delivering superior tensile strength and resistance to fatigue under extreme conditions. The kit includes a full set of bolts, nuts, and washers, all finished with a durable painted coating to protect against corrosion and wear.

Designed specifically for balancing applications, these bolts provide a precise fit for a wide range of performance engines. The dimensions—4 × 2 × 6 inches and a weight of just 11.3 ounces—make them easy to handle while offering the robustness required for high‑rpm operation. The kit’s components are manufactured in the United States, ensuring tight tolerances and consistent performance across every piece.

Usage

These balancer bolts are ideal for both street‑legal builds and track‑focused engines. Whether you are installing a new crankshaft, upgrading a rotating assembly, or performing a complete engine rebuild, the ARP 147-2501 kit provides the confidence that every fastener will hold true under load. The bolts are compatible with most aftermarket and OEM crankshafts that require a 147‑2501 specification, making them a versatile choice for a variety of platforms.

Professional mechanics and dedicated hobbyists alike appreciate the ease of installation. The bolts feature a standard thread pitch that works seamlessly with common torque wrenches, and the included hardware ensures a complete, bolt‑to‑nut match without the need for additional parts. This reduces installation time and minimizes the risk of mismatched components during critical engine assembly procedures.
