Part #: SPL CRBN F3IX

Overview

The SPL Parts FKS Series Front Caster Rod Bushing Set is designed to enhance the handling and suspension performance of your BMW 435i xDrive from 2014 to 2016. These high-quality bushings replace the factory rubber components with precision-engineered spherical bearings, providing a significant upgrade in steering response, stability, and overall driving dynamics. Whether you're a spirited street driver or a track enthusiast, this bushing set helps you achieve more precise suspension geometry and improved feedback under load.

Constructed with performance in mind, these bushings eliminate the deflection and flex associated with stock rubber bushings, ensuring your suspension maintains optimal alignment during aggressive driving. The result is sharper turn-in, reduced understeer, and a more connected driving experience. Designed for durability and maximum performance, these bushings are ideal for enthusiasts seeking to push their vehicle's handling capabilities to the next level.

Key Features

The SPL Parts FKS Series Bushings incorporate several advanced features to deliver superior performance and longevity:

• Massive 1" FK Racing Bearings with self-lubricating Teflon liners provide low friction articulation, ensuring smooth movement and reducing wear over time.
• High-strength 6061-T6 aluminum bearing housings offer excellent durability and resistance to corrosion, maintaining integrity under demanding driving conditions.
• Replace the stock flexible rubber bushings with low-friction spherical bearings, eliminating bushing deflection and improving suspension geometry consistency.
• Designed specifically for the front caster rods, these bushings help maintain proper alignment during aggressive cornering and braking.
• Engineered to withstand the rigors of spirited driving and track use, providing a reliable upgrade for performance-minded drivers.
• Precision CNC-machined components ensure a perfect fit and easy installation, with minimal modification required.
• Enhanced handling feedback and reduced flex contribute to more predictable steering and improved driver confidence.
• Self-lubricating Teflon liners reduce maintenance needs and ensure long-lasting performance without the need for frequent lubrication.

Construction & Design

The SPL Parts bushings feature a robust construction combining high-quality materials for maximum durability and performance. The spherical bearings are housed within CNC-machined 6061-T6 aluminum brackets, which are lightweight yet incredibly strong. The use of FK Racing Bearings with Teflon liners ensures low friction articulation, allowing for precise movement and minimal wear. The design eliminates the stock rubber bushings' compliance, providing a more direct and responsive connection between the suspension components.

This setup not only improves handling but also enhances feedback from the road, giving you better control during aggressive driving or track days. The components are engineered with tight tolerances to ensure a perfect fit, and the overall design emphasizes longevity and resistance to harsh driving conditions.
