What a 6-Inch Lift Does for the Toyota 4Runner
Lifting a 4Runner by six inches delivers more than height. It reshapes the vehicle’s entire driving personality. On the trails, it improves clearance for obstacles, reduces underbody risk, and enhances performance in uneven terrain. On pavement, the lift elevates the driver’s visibility and road presence.
Key improvements include:
- Ground Clearance Boost: The underbody sits significantly higher, which helps avoid rocks, deep ruts, and snow buildup.
- Larger Tire Fitment: A 6-inch lift comfortably accommodates 33–35 inch tires, depending on wheel offset and minor trimming.
- Improved Angles:
- Approach angle: typically increases from ~33° to 37–40°
- Departure angle: often shifts from ~26° to 30–32°
- Breakover angle: improves substantially, especially with larger tires
- Approach angle: typically increases from ~33° to 37–40°
- Commanding Stance: The visual change alone can transform how the 4Runner looks and feels.
Real-World Example
A 5th-gen Toyota 4Runner equipped with a 6-inch suspension lift and 35×12.50R17 tires documented a 4.2-inch increase in underbody clearance and a measurable reduction in skid-plate contact during boulder fields in Colorado. The driver noted “a massive difference in breakover capability on long cross-axle climbs.”
Types of Toyota 4Runner 6 Inch Lift Kits
A variety of 6-inch lift systems are available, and each one suits different driving needs. Some kits maximize articulation for off-road use, while others prioritize daily driving comfort. Understanding each lift type helps you choose the right system for your goals.
Main Lift Kit Categories
Suspension Lift Kits
These are the most common, providing a true 6-inch suspension height increase. They include upgraded shocks, coilovers, springs, control arms, and drivetrain geometry corrections.
Best for: off-roading, overlanding, and serious height gains.
Body Lift Kits
A body lift raises the body from the frame using spacers without altering suspension geometry. While cheaper, a body lift alone cannot achieve a full 6 inches safely.
Best for: minor height gains, cosmetic changes, and supplementing a suspension lift.
Hybrid Lift Systems
A combination approach: a 4–5 inch suspension lift paired with a smaller 1–2 inch body lift.
Best for: drivers seeking full tire clearance with improved ride quality.
Key Components Included in a 6-Inch Lift Kit
A complete Toyota 4Runner 6 inch lift kit typically includes several critical parts designed to maintain proper suspension geometry, drivability, and long-term reliability. Each component plays a specific role in handling, articulation, and overall height gain.
Common Components in a High-Quality 6-Inch Lift Kit
Upgraded Shocks & Struts
These handle the increased travel and weight changes that come with a full lift. High-end options like remote reservoir shocks improve heat dissipation and durability on long off-road runs.
Coilovers
Performance coilovers replace factory struts and allow for fine-tuning of ride height and damping, giving the 4Runner a balanced stance and smoother suspension response.
Upper Control Arms (UCAs)
After a 6-inch lift, UCAs help correct caster and camber so the SUV aligns properly. High-quality UCAs also increase articulation angles and reduce joint stress.
Rear Springs
These maintain lift height in the rear and support additional cargo weight—especially useful for overlanding setups or when carrying rooftop tents and gear.
Drop Brackets & Crossmembers
These components reposition key suspension points to maintain factory geometry, reduce CV angles, and prevent premature wear.
Sway Bar Relocation Hardware
Raising the 4Runner changes sway bar positioning. Relocation brackets ensure the bar sits at the correct angle to prevent binding.
Extended Brake Lines
Lifts increase suspension travel, so longer brake lines ensure the system operates safely without stretching under articulation.
Typical Component Setup Table
| Component | Purpose | Notes |
| Coilovers | Ride height + damping control | Ideal for off-road flex and tuning |
| Shocks | Smooth out impacts | Reservoir shocks preferred for heat management |
| UCAs | Correct alignment angles | Necessary for 6” lifts |
