Ball Joint MOOG Front Suspension Replacement K9513 Heat Treated Steel

Description

Product Overview

The MOOG K9513 front ball joint is a precision‑engineered component designed to meet the demanding performance standards of Subaru vehicles. Constructed from heat‑treated steel, the ball studs are processed to exceed original equipment specifications, providing exceptional fatigue resistance and strength. The exterior is machined to a tight tolerance, ensuring a perfect fit and smooth operation throughout the steering system. A Belleville preload washer is integrated to keep the bearing package tight as wear occurs, preserving alignment and reducing the risk of premature failure.

In addition to its robust construction, the K9513 features a patented pressed‑in cover plate that seals out contaminants such as dust, water, and road debris. This protective design minimizes bearing wear and helps maintain consistent steering feel over the life of the part. The ball joint is lightweight, weighing only 11.5 ounces, yet it delivers the durability required for both daily driving and more aggressive off‑road use. Its compact dimensions of 0.4 x 1.7 x 0.4 inches make it an ideal replacement for a wide range of Subaru models, including the XV Crosstrek, WRX, WRX STI, and Baja.

Usage

Designed for front‑end suspension applications, this ball joint is suitable for a variety of driving conditions. Whether navigating city streets, tackling winding mountain roads, or enduring the rigors of winter weather, the K9513 provides reliable steering response and stability. It is especially beneficial for owners seeking to restore original handling characteristics after wear or damage to the factory ball joint.

Installation is straightforward for experienced DIY mechanics, thanks to the precision tolerances that align the steering geometry right out of the box. The part fits seamlessly into the existing suspension architecture, reducing the need for additional adjustments or aftermarket modifications. For professional service centers, the K9513 offers a quick swap that minimizes vehicle downtime, allowing technicians to deliver prompt, high‑quality service to their customers.
