SPL Parts Front Spherical Caster Rod Bushing Set

2013–2018 BMW 320i (F30) / 2013–2015 BMW 335i (F30) 2.0L Turbo / 3.0L Inline-Six

Part #: SPL CRBN F3IX

Overview

The SPL Parts FKS Series Front Caster Rod Bushing Set is designed to enhance the suspension performance of your BMW F30 series. Specifically engineered for models from 2013 to 2018, including the 320i and 335i, this upgrade replaces the factory rubber bushings with high-performance spherical bearings. Whether you're a spirited driver, track enthusiast, or someone seeking improved handling and responsiveness, this bushing set offers a significant upgrade over stock components.

By replacing the flexible rubber bushings with low-friction, articulating spherical bearings, you'll experience more precise suspension geometry under load. This translates to sharper steering response, reduced bushing deflection, and improved feedback during aggressive driving or cornering. The result is a more connected driving experience, with enhanced stability and control that can elevate your BMW's handling capabilities.

Key Features

The SPL Parts FKS Series Front Caster Rod Bushings incorporate advanced materials and engineering to deliver maximum performance and durability. Here are some of the standout features:

• High-Quality Materials: Crafted from 6061-T6 aluminum, these bushings are lightweight yet robust, providing excellent strength and corrosion resistance for long-lasting performance.
• Massive FK Racing Bearings: Equipped with 1" FK Racing spherical bearings, these bushings eliminate bushing deflection, ensuring consistent suspension geometry under load.
• Self-Lubricating Teflon Liners: The bearings feature Teflon liners that reduce friction and maintenance needs, allowing for smooth articulation and extended service life.
• Precision Engineering: Designed to maintain the factory suspension geometry while providing a more direct and responsive feel during driving.
• Enhanced Handling: The spherical bearings help reduce unwanted movement and flex, resulting in improved steering precision and feedback.
• Easy Installation: Designed as a direct replacement for OEM bushings, these components install with standard tools and do not require modifications.

Construction & Design

The SPL Parts FKS Series bushings are meticulously engineered with a focus on durability and performance. The use of 6061-T6 aluminum ensures a lightweight yet sturdy housing that withstands the rigors of spirited driving. The massive FK Racing spherical bearings are precision-machined to exact specifications, providing a tight fit and reliable articulation. The self-lubricating Teflon liners inside the bearings minimize maintenance and friction, promoting smooth operation over time.

The design maintains the original suspension geometry, ensuring compatibility and ease of installation. The articulation provided by the spherical bearings reduces bushing deflection, which can occur with rubber bushings under load, thereby improving handling response and steering feel. Overall, the construction choices optimize the balance between performance, durability, and ease of use.

Installation & Fitment
