Construction & Design

The SPL Parts caster rod bushings feature a precision-machined design utilizing high-grade 6061-T6 aluminum, known for its excellent strength-to-weight ratio and corrosion resistance. The core of each bushing is a massive 1" FK Racing spherical bearing, which provides a low-friction, articulating joint that maintains consistent suspension geometry under load. The self-lubricating Teflon liners inside the bearings reduce maintenance and ensure smooth operation over time.

The combination of lightweight aluminum and durable spherical bearings results in a product that not only improves handling but also maintains structural integrity and longevity. The design ensures a perfect fit with OEM mounting points, making installation straightforward without the need for additional modifications. These bushings are a testament to SPL Parts' commitment to high-performance suspension components that deliver both function and durability.

Installation & Fitment
