Cusco 116 919 A Rear Control Arm Hyper Rubber Bushing Set

The Cusco 116 919 A is a rear control arm bushing set engineered as a direct performance upgrade over stock rubber bushings. Cusco's Hyper Rubber bushings are purpose-built for drivers who want improved handling response and suspension precision without sacrificing street drivability.

Hyper Rubber Bushing — Reinforced Rubber Construction:

• Manufactured from high-durometer hyper rubber rated at 70–90 Shore degrees, significantly firmer than the 40–50 degree rubber used in OEM bushings
• Greater hardness reduces deflection under load, improving steering response and rear-end stability
• Bushings are pre-pressed into metal cases for straightforward, drop-in installation
• Retains a degree of compliance for improved street comfort compared to full urethane or pillowball alternatives

Cusco Bushing Technology Overview:

• Hyper Rubber — Best for street and light performance use; firmer than OEM with easier installation
• Urethane — Maximum durability with excellent corrosion and heat resistance; ideal for applications requiring smooth articulation; available in bright pink for easy identification
• Pillowball — Racing-grade option for maximum precision and zero deflection

This set includes 2 bushings for the rear control arm. Cusco, a brand developed under Carrosser — Japan's only independent motorsport-focused manufacturer — applies real-world racing and rally experience to every component in their suspension lineup.
