Superior Engineering — Suspension Arms
Heavy-duty arms engineered for lift, load and long-distance touring. Improve wheel alignment, strength and articulation while maintaining on-road manners.
Overview
Superior Engineering suspension arms are purpose-built replacements for OE arms to correct geometry on lifted vehicles, increase durability in harsh conditions and provide precise adjustability for alignment and handling.
Product Families
- Upper Control Arms (UCAs): Increase caster & ball-joint/uni-ball clearance on IFS vehicles, restoring alignment after a lift and improving droop travel.
- Radius Arms: Heavy-duty arms (with or without drop boxes) for live-axle 4WDs to correct caster, enhance tracking stability and improve ride over corrugations.
- Trailing Arms (Upper/Lower): Reinforced arms for rear live-axle vehicles to resist bending, control axle movement and improve articulation.
- Panhard Rods (Adjustable): Recentre the axle after a lift and sharpen steering response by correcting lateral alignment.
- Adjustable Arms & Hardware: Fine-tune wheelbase, pinion angle and caster for tailored handling and tyre wear.
Key Features
- High-strength construction: Boxed plate/chromoly steel or billet alloy (application-dependent) for maximum rigidity and impact resistance.
- Geometry correction: Built-in caster gain, clearance for larger CVs/ball joints and optimised shock/coil interaction on lifted setups.
- Serviceable ends: Quality bushes, uni-balls or heavy-duty ball joints for durability and precise steering feel.
- Adjustability: Threaded adjusters or eccentric-friendly designs to dial in caster, camber (IFS), toe and pinion angle.
- Protected finishes: Powder-coat/anodised finishes and sealed joints for corrosion resistance in coastal and outback conditions.
Benefits
- Straighter tracking and reduced wander after fitting larger tyres and lifts.
- Improved bump compliance, articulation and droop for off-road control.
- Restored alignment specs to reduce tyre wear and CV/uni-joint stress.
- Greater component clearance at full compression/extension.
