SuperPro TRC1416 Caster Correction Radius Arm Assembly Kit 4-6" Lift

The SuperPro TRC1416 is a front caster correction radius arm assembly engineered for lifted 4x4 vehicles. Designed to restore proper caster geometry on vehicles that have been raised 4–6 inches, this arm assembly addresses the alignment issues that arise when common 4x4s are lifted beyond the factory suspension range.

When a vehicle is lifted above standard height, the factory caster and camber settings are immediately disrupted, leading to vague steering response, directional wander, and accelerated tire wear. The SuperPro TRC1416 corrects these geometry deficiencies, restoring stability, steering precision, and confidence both on and off the road.

Key Features:

• Caster Correction Design: Engineered specifically to restore proper caster angles on vehicles lifted 4–6 inches
• High-Strength Construction: Manufactured using high-strength, high-toughness steel with a robotically welded internal section for superior rigidity and reduced unsprung weight
• SuperPro Polyurethane Bushings: Pre-fitted with proprietary SuperPro bushings that allow full articulation and movement without binding and with no increase in noise, vibration, or harshness (NVH)
• Heavy-Duty Ball Joint: Includes an upgraded ball joint designed for greater articulation, reduced wear, and improved durability compared to OEM components
• Complete Arm Assembly: Supplied as a complete, ready-to-install arm replacement — no additional bushing or hardware kits required
• Direct Replacement: Designed as a straight-swap replacement requiring no modification during installation
• 3-Year Warranty: Backed by SuperPro's three-year warranty for TRC-series control and radius arm assemblies, valid across off-road, racing, and motorsport applications
• Australian Engineered: Designed, tested, and manufactured in Brisbane, Australia to exacting quality standards

SuperPro strongly advises replacing both arms simultaneously to maintain correct suspension geometry and prevent alignment issues. A professional wheel alignment is required following installation.
