Super Pro TRC1155 Caster Adjustment Kit

The Super Pro TRC1155 is a caster adjustment kit from SuperPro's Roll Control suspension range, engineered to restore or optimize front suspension caster geometry. Proper caster angle is critical for straight-line stability, steering returnability, and cornering performance — and can be negatively affected by suspension lifts, lowering, or worn components.

Key Features:

• Designed to adjust and correct front suspension caster angle
• Part of SuperPro's Roll Control (TRC) product range, backed by a 3-year warranty
• Manufactured from SuperPro's proprietary engineering-grade polyurethane — more durable and longer-lasting than OEM rubber
• Restores lost caster caused by suspension modification or component wear
• Improves straight-line tracking and steering self-centering behavior
• Reduces steering pull, wander, and instability at speed
• No negative impact on ride comfort or NVH (noise, vibration, harshness)

SuperPro is a leading Australian manufacturer of aftermarket suspension components, designing and producing all products in Brisbane, Australia. The TRC1155 is built to outperform OEM specifications and is an ideal solution for vehicles that have experienced alignment issues following a suspension modification or component replacement.
