What Is a 6 Inch Lift Kit for a Toyota 4Runner?
A 6 inch lift kit raises the body and frame of the vehicle approximately six inches higher than factory ride height. On a Toyota 4Runner, this is typically accomplished through a combination of:
- Suspension lift components
- Crossmember modifications
- Extended shocks and struts
- Differential drop brackets
- Lifted rear suspension components
- Steering and alignment corrections
Unlike small leveling kits or 2-inch spacer lifts, a true 6-inch suspension lift substantially changes the geometry of the suspension system.
Most kits are designed for:
- Improved off-road articulation
- Larger tire clearance
- Better approach and departure angles
- Aggressive appearance
- Rock crawling and trail use
A properly engineered 6-inch lift should maintain safe steering and suspension operation while increasing ride height.
Quick Summary: Is a 6 Inch Lift Worth It?
| Driver Type | Is It Worth It? |
| Serious off-road enthusiast | Yes |
| Weekend trail rider | Possibly |
| Daily commuter | Usually not ideal |
| Overlanding build | Often beneficial |
| Towing-focused owner | Depends on setup |
| Urban-only driver | Rarely necessary |
A 6-inch lift is best suited for drivers who frequently tackle difficult trails, deep mud, rocky terrain, or want to run 35-inch tires.
Benefits of a 6 Inch Lift Kit on a Toyota 4Runner
Increased Ground Clearance
The most obvious benefit is additional clearance under the frame, skid plates, and suspension components.
This helps when:
- Crossing rocks
- Driving through ruts
- Climbing steep obstacles
- Navigating deep snow or mud
Factory 4Runners already have respectable clearance, but a 6-inch lift takes capability much further.
Larger Tire Compatibility
A major reason people install a tall lift is to fit larger off-road tires.
Typical tire sizes with a 6-inch lift include:
- 33-inch tires
- 34-inch tires
- 35-inch tires
Larger tires improve:
- Traction
- Obstacle clearance
- Off-road grip
- Visual stance
However, tire size depends on wheel offset, body trimming, and suspension travel.
Improved Off-Road Angles
A lifted 4Runner can improve:
- Approach angle
- Breakover angle
- Departure angle
These measurements matter when climbing hills, descending obstacles, or driving uneven terrain.
More Suspension Travel
High-quality lift kits often include upgraded shocks and longer suspension travel.
Benefits include:
- Better articulation
- Improved wheel contact on uneven terrain
- Increased comfort off-road
- Reduced bottoming out
Aggressive Appearance
Many owners simply prefer the rugged look of a lifted 4Runner.
A 6-inch lift creates:
- Taller stance
- Wider visual footprint
- More wheel well clearance
- Classic off-road styling
Drawbacks of a 6 Inch Lift Kit
A large suspension lift also introduces compromises that many buyers underestimate.
Higher Center of Gravity
Raising the vehicle increases rollover risk during:
- Emergency maneuvers
- High-speed cornering
- Sudden lane changes
The 4Runner already has a relatively tall profile, so suspension tuning becomes critical.
Reduced Fuel Economy
Larger tires and increased aerodynamic drag usually reduce MPG.
Owners commonly experience:

Poor-quality lift kits accelerate wear dramatically.
More Difficult Entry and Exit
A lifted 4Runner can become inconvenient for:
- Children
- Elderly passengers
- Daily commuting
Side steps or rock sliders often become necessary.
Alignment Challenges
Improper geometry correction can cause:
- Uneven tire wear
- Wandering steering
- Vibration
- Poor handling
This is why professional alignment is essential after installation.
Components Included in a Typical 6 Inch Lift Kit
Not all lift kits are equal. Quality systems usually include far more than spacers.
Front Suspension Components
Common parts include:
- Lifted struts or coilovers
- Extended knuckles
- Crossmembers
- Differential drop brackets
- Sway bar relocation brackets
These help maintain proper suspension angles.
Rear Suspension Components
Rear lift components often include:
- Lift springs
- Long-travel shocks
