Toyota 4Runner Parts, Suspension & Performance Upgrades

The Toyota 4Runner is built to be rugged and capable — but many owners find that thoughtfully selected upgrades improve its ride quality, off-road capability, utility, and everyday drivability. Whether you’re exploring backroads, towing gear, or navigating daily traffic, this collection brings together performance parts and accessories that solve real-world problems and enhance how your 4Runner performs.

This page is engineered around the core areas most 4Runner owners care about: suspension control, load support, lighting and visibility, airflow and exhaust efficiency, utility accessories, protection, and reliable communication systems.

4Runner Suspension, Ride Control & Off-Road Geometry

Upgrading suspension makes a dramatic difference in how the 4Runner handles loaded driving and off-road terrain.

ICON Vehicle Dynamics suspension systems improve wheel travel, articulation, and overall ride feel by using engineered geometry components that reduce harshness and improve stability on rugged trails.

FOX performance shock absorbers offer consistent damping control that reduces body motion and improves suspension response over rough terrain, washboards, and uneven surfaces.

For improved stance and handling balance, Belltech suspension components help refine ride height and alignment for everyday driving and lifted setups alike.

When lifted or modified, maintaining proper geometry is critical — Camburg components help retain steering precision and tire wear control by correcting suspension angles in lifted applications.

4Runner Load Support & Ride Stability

Rear support systems provide greater stability when carrying gear, camping equipment, or towing trailers.

Air Lift air springs give adjustable support to maintain proper ride height under load, improving braking stability and steering feel.

For a no-maintenance support solution, Firestone air spring systems help maintain level stance and reduce rear sag under heavy loads.

4Runner Exhaust & Airflow Performance

Exhaust flow and engine breathing upgrades improve responsiveness and deliver a more confident driving experience.

Borla exhaust systems are engineered to provide smoother airflow and a refined performance tone without excessive drone.

For broader exhaust enhancement options, Magnaflow products help improve exhaust efficiency while offering a deeper, performance-oriented sound.

4Runner Lighting & Visibility Enhancements

High-output lighting makes a huge difference on trails, rural roads, and low-light environments.

Baja Designs auxiliary lighting products are engineered to deliver powerful, balanced beam patterns that increase visibility without edge glare.

KC HiLiTES lighting systems provide focused illumination where it’s needed most — whether on the trail, at camp, or on dark highways.

Rigid Industries lighting solutions round out the high-performance lighting lineup with durable products designed for repeated use in rugged conditions.

4Runner Accessibility & Utility Upgrades

Functional accessories help make your 4Runner easier to use every day.

AMP Research powered running boards deploy when doors open and retract when closed, providing easier access without compromising approach angles or clearance.

4Runner Communication & Support Systems

Communication gear enhances coordination and safety on trail runs and group travel.

Rugged Radios systems provide dependable two-way communication in environments where cell coverage can’t be relied upon, keeping drivers connected regardless of terrain or distance.

Integrated Handling & Ride Balance

Whether you’re tackling trails or highways, King Shocks performance dampers help manage suspension movement with precise control, reducing harsh rebound and improving confidence in varied conditions.

4Runner Fitment & Compatibility Notes

Before selecting parts for your 4Runner, confirm:

• Exact years, make, and model

• Suspension goals (daily ride quality vs off-road capability)

• Load conditions (camping gear, cargo, towing)

• Wheel and tire size plans

Matching parts carefully to your setup ensures proper fitment, expected performance benefits, and long-term reliability.
