Overview

The SuperPro Front Control Arm Upper-Inner Bushing Kit is designed to restore and enhance the handling and stability of your Lexus IS F from 2008 to 2014. Over time, the factory rubber bushings in the control arms can wear out, leading to compromised wheel alignment, increased tire wear, and less precise handling. This kit provides a reliable upgrade or replacement solution to maintain optimal suspension geometry and driving dynamics.

Whether you're a daily driver seeking improved ride quality or a performance enthusiast aiming for sharper handling, this bushing kit helps ensure your vehicle responds accurately to driver inputs. By replacing worn or degraded bushings, you'll experience more consistent steering, better cornering, and increased confidence behind the wheel.

Construction & Design

This bushing kit features a one-piece polyurethane construction that combines strength with flexibility. The polyurethane material is formulated to withstand harsh driving conditions, including exposure to heat, oil, and road debris, without degrading or losing its shape. The design ensures a snug fit within the control arm, providing consistent performance and reducing unwanted movement.

SuperPro's engineering team utilized CAD modeling and rigorous testing to develop bushings that replicate or improve upon the factory specifications. The result is a component that maintains proper suspension geometry, enhances handling, and prolongs the lifespan of your suspension system.
