SPL Parts FKS Series Adjustable Front Caster Rod Bushings

2020–2023 Toyota Supra (A90) / Front Suspension / Adjustable Caster Bushings

Part #: SPL CRB G29

Overview

The SPL Parts FKS Series Adjustable Front Caster Rod Bushings are a high-performance upgrade designed specifically for the 2020-2023 Toyota Supra (A90). These bushings replace the factory rubber components with precision-engineered spherical bearings, offering a significant improvement in suspension responsiveness and handling precision. Whether you're a spirited street driver, a track enthusiast, or someone seeking to optimize your Supra's suspension geometry, these adjustable bushings provide the performance and durability you need.

By eliminating bushing deflection and reducing friction, these spherical bearings help maintain consistent suspension geometry under load, resulting in improved steering feedback, enhanced braking stability, and more predictable handling characteristics. The upgrade is ideal for drivers looking to fine-tune their suspension setup for better cornering, reduced body roll, and increased driver confidence on both street and track environments.

Key Features

The SPL FKS Series Adjustable Front Caster Rod Bushings incorporate several advanced features designed for maximum performance and longevity:

• Constructed with massive 1" FK Racing Bearings featuring self-lubricating Teflon liners, these bushings ensure smooth articulation and long-lasting durability even under aggressive driving conditions.
• Precision CNC-machined aluminum housings provide a lightweight yet robust structure, ensuring perfect fitment and resistance to corrosion.
• Adjustability allows for fine-tuning of caster angle, enabling you to optimize suspension geometry for your specific driving style or track setup.
• Designed to replace the stock flexible rubber bushings, these spherical bearings eliminate bushing deflection, translating to more direct steering response and improved handling feedback.
• Engineered for high-performance applications, these bushings are suitable for both street and track use, providing a balance of comfort and precision.
• Massive FK Racing Bearings with self-lubricating Teflon liners help reduce maintenance needs and ensure consistent performance over time.

Construction & Design

The SPL Parts FKS Series bushings feature a meticulously crafted design that combines durability with performance. The CNC-machined aluminum housings are lightweight yet strong, providing a precise fit that maintains alignment and suspension integrity. The core of the assembly, the 1" FK Racing spherical bearings, are engineered for maximum articulation and minimal friction, thanks to their self-lubricating Teflon liners. This design ensures smooth movement and reduces wear, even during aggressive driving or track sessions.

The adjustability feature is achieved through threaded components that allow you to set the caster angle to your preference. This flexibility enables you to optimize handling characteristics for different driving conditions, whether you're seeking sharper turn-in or more stability at high speeds. The overall construction emphasizes longevity, with corrosion-resistant materials and high-quality manufacturing processes ensuring these bushings will perform reliably for years to come.

Installation & Fitment

The SPL Parts FKS Series Adjustable Front Caster Rod Bushings are designed as a direct bolt-on upgrade for the 2020-2023 Toyota Supra (A90). Installation typically involves removing the factory caster bushings and replacing them with the new spherical bearing assemblies. The process is straightforward for those with basic mechanical skills and the proper tools. No cutting, drilling, or complex modifications are required. For optimal results, alignment adjustments are recommended after installation to ensure proper suspension geometry and handling characteristics.
