Construction & Design

The SuperPro caster bushing kit features a one-piece polyurethane construction that is engineered for maximum durability and performance. The bushings are designed with a precise fit to ensure proper alignment and function within the control arm assembly. The material's inherent stiffness helps reduce unwanted suspension movement, translating into sharper steering and improved cornering grip.

SuperPro's manufacturing process involves CAD development and precision molding, resulting in bushings that maintain their shape and performance over time. The bushings are resistant to oil, grease, and other automotive fluids, making them suitable for long-term use without degradation. The design also minimizes NVH (noise, vibration, harshness), providing a comfortable driving experience while delivering enhanced handling.

Installation & Fitment

The SuperPro Front Lower Rearward Control Arm Caster Bushing Kit is a direct replacement for the original factory bushings. Installation is straightforward for those with basic suspension knowledge, as it uses the existing control arm mounting points. No cutting, drilling, or complex modifications are required. However, it is recommended to use proper tools such as a bushing press or hydraulic press to ensure correct installation and prevent damage to the new components.

• Designed specifically for the front lower control arm's rearward bushings on 1986–1991 Mazda RX-7 models
• Installation typically involves removing the control arm from the vehicle for press-fit replacement
