SPL Parts FKS Series Front Spherical Caster Rod Bushing Set

2015–2016 BMW 228i xDrive (F22/F23)

Part #: SPL CRBN F3IX

Overview

The SPL Parts FKS Series Front Spherical Caster Rod Bushing Set is designed to enhance the handling and suspension performance of your BMW 228i xDrive. Specifically engineered for the 2015 and 2016 models, these high-quality bushings replace the factory rubber components with precision spherical bearings, delivering a more responsive and predictable driving experience. Whether you're a spirited street driver or a track enthusiast, this upgrade helps you achieve better steering feedback, improved cornering stability, and more consistent suspension geometry under load.

By replacing the stock flexible bushings with low-friction, articulating spherical bearings, you'll notice a significant reduction in bushing deflection and friction. This results in more direct steering response and enhanced feedback from the road, allowing you to better feel and control your vehicle. The robust design ensures durability and long-lasting performance, making it an ideal upgrade for those seeking to optimize their BMW's handling characteristics without sacrificing reliability.

Key Features

• Made from high-grade 6061-T6 aluminum, ensuring lightweight strength and corrosion resistance.
• Designed to eliminate bushing deflection, maintaining optimal suspension geometry under load for improved handling feedback.
• Precisely engineered to fit the 2015-2016 BMW 228i xDrive (F22/F23), ensuring a perfect, bolt-on installation.
• Reduces friction compared to stock rubber bushings, resulting in more immediate steering response.
• Ideal for enthusiasts looking to improve braking, cornering, and overall suspension feel.
• Manufactured with high-precision CNC machining for consistent quality and fitment.

Construction & Design

The SPL Parts FKS Series Bushings are built with a focus on strength, precision, and longevity. The core spherical bearings are crafted from durable FK Racing components, featuring a 1" diameter for maximum load capacity and smooth operation. The self-lubricating Teflon liners inside the bearings reduce maintenance needs and ensure consistent articulation over time. The aluminum housings are CNC-machined from 6061-T6 aluminum, a lightweight yet robust material that resists corrosion and withstands the rigors of spirited driving and track use.

This design eliminates the flex and deflection inherent in rubber bushings, providing a more direct connection between the suspension components and the chassis. The result is improved steering feel, sharper turn-in, and enhanced stability during aggressive maneuvers. The precise engineering and high-quality materials ensure a long-lasting upgrade that maintains performance even under demanding conditions.

Installation & Fitment

The SPL Parts FKS Series Bushings are designed as a direct bolt-on upgrade for the 2015-2016 BMW 228i xDrive (F22/F23). Installation involves removing the existing rubber bushings and replacing them with the spherical bearing set. The process typically requires basic hand tools and does not necessitate cutting, drilling, or extensive modifications. For optimal results, some familiarity with suspension components is recommended, but no specialized tuning or alignment adjustments are usually required beyond standard procedures.

Proper installation ensures maximum performance benefits and longevity of the components. It is advisable to follow the included instructions or consult a professional if unsure about the procedure.
