KING 2.5 Performance Suspension Kit with Dirt King UCAs - Toyota Tundra 2022-Current
KING 2.5 Performance Suspension Kit with Dirt King 4130 Upper Control Arms
Upgrade your Toyota Tundra with a complete Trail Ready performance suspension system built around KING’s legendary 2.5 remote-reservoir shocks and Dirt King’s heavy-duty 4130 upper control arms.
This package is designed for Tundra owners who want more than a basic lift or shock replacement. By combining premium front and rear damping with upgraded upper control arms, the system improves suspension control, heat management, articulation, alignment capability, and overall confidence across pavement, trails, washboard roads, desert terrain, and demanding backcountry conditions.
Whether your Tundra serves as a daily driver during the week and a trail truck on the weekend or is being built into a serious adventure platform, this package provides a substantial suspension upgrade without stepping into a full long-travel system.
KING 2.5 Front Remote-Reservoir Coilovers
The front suspension is built around a pair of KING 2.5 coilovers engineered specifically for the Tundra platform.
KING's large 2.5-inch shock bodies provide increased fluid capacity compared with smaller factory-style dampers. Greater fluid capacity helps control operating temperatures and maintain consistent damping during prolonged use over rough terrain.
External reservoirs further increase oil and gas capacity while helping dissipate heat during repeated suspension cycling. This becomes especially valuable on washboard roads, desert terrain, extended trail runs, and other conditions where conventional shocks can begin to lose performance as temperatures increase.
KING's vehicle-specific tuning provides a controlled and composed ride without sacrificing the compliance needed for everyday driving.
Front suspension features include:
- KING 2.5 performance coilovers
- External remote reservoirs
- Vehicle-specific KING shock tuning
- Adjustable front ride height
- Increased suspension performance and wheel travel
- Large 2.5-inch shock bodies
- Increased fluid capacity and heat management
- High-quality aluminum construction
- Fully rebuildable and serviceable design
- Tunable for future vehicle modifications or specialized applications
- Premium racing-derived KING shock technology
KING 2.5 Rear Remote-Reservoir Shocks
A matched pair of KING 2.5 remote-reservoir rear shocks completes the damping package.
Rather than upgrading only the front suspension, the matched rear shocks provide balanced damping throughout the truck. This helps improve chassis control during acceleration, braking, cornering, trail driving, and repeated impacts.
The larger shock bodies and external reservoirs provide the additional fluid capacity and cooling required for sustained performance in demanding environments.
Rear suspension features include:
- KING 2.5 rear shocks
- External remote reservoirs
- Vehicle-specific damping
- Increased rear suspension control
- Increased wheel travel compared with the factory configuration
- Greater fluid capacity
- Improved heat dissipation
- Consistent damping during extended off-road use
- Fully rebuildable and serviceable construction
- Heavy-duty components designed for demanding use
Dirt King 4130 Upper Control Arms Included
This package also includes a complete pair of Dirt King 4130 upper control arms, making it a much more comprehensive suspension system than a conventional front-and-rear shock package.
Lifting the front suspension changes factory suspension geometry. Upgraded upper control arms provide additional alignment capability while allowing the upgraded coilovers and front suspension to operate more effectively through their available travel.
Dirt King's 4130 UCAs are engineered for lifted and performance-oriented Tundra applications and are an excellent complement to the KING coilovers.
Their heavy-duty construction, upgraded ball joints, and specialized bushings provide the strength and articulation expected from a suspension system intended for regular off-road use.
Dirt King UCA features include:
- Heavy-duty 4130 construction
- Driver and passenger upper control arms included
- Designed for lifted Tundra applications
- Increased alignment capability
- Improved suspension geometry
- Increased articulation
- Heavy-duty Pro 4 ball joints
- Maintenance-free SilentSpin bushings
- Designed for use with performance aftermarket coilovers
- Built for demanding street and off-road environments
Choose Your Suspension Configuration
Two KING configurations are available so you can select the level of adjustability that best matches how you use your Tundra.
Standard — Factory Tuned
The Standard configuration provides KING's premium vehicle-specific damping without external compression-adjustment knobs.
This is an excellent choice for drivers who want a high-performance suspension that is ready to perform right out of the box without requiring frequent adjustments.
You still receive the major benefits of the KING platform, including large 2.5-inch shock bodies, external reservoirs, rebuildable construction, increased suspension capability, and the included Dirt King upper control arms.
Standard configuration includes:
- Pair of KING 2.5 front remote-reservoir coilovers
- Pair of KING 2.5 rear remote-reservoir shocks
- Pair of Dirt King 4130 upper control arms
- KING reservoir mounting hardware
Best suited for:
Daily driving, weekend trail use, camping, backcountry exploration, fire roads, moderate-to-aggressive recreational off-road use, and customers who prefer a premium set-it-and-drive-it suspension.
Compression Adjustable — Maximum Tuning Control
The Compression Adjustable configuration upgrades both the front and rear KING shocks with external compression adjusters.
This gives the driver substantially more control over how the suspension responds to changing vehicle loads, terrain, and driving conditions.
Compression adjustment is particularly valuable for trucks that regularly transition between different uses. A Tundra may be unloaded during everyday driving but carry camping equipment, recovery gear, cargo, or additional weight on weekend trips.
The adjustable system allows suspension behavior to be fine-tuned instead of relying on one fixed damping configuration for every situation.
Compression Adjustable configuration includes:
- Pair of KING 2.5 front remote-reservoir coilovers with compression adjustment
- Pair of KING 2.5 rear remote-reservoir shocks with compression adjustment
- Pair of Dirt King 4130 upper control arms
- KING reservoir mounting hardware
Best suited for:
Aggressive trail driving, desert terrain, changing payloads, towing, heavily equipped trucks, frequent off-road use, and drivers who want greater control over suspension tuning.
Why Choose This Complete System?
A properly designed suspension package is about much more than simply increasing ride height.
This system addresses several important areas of suspension performance at the same time.
Improved damping control helps keep the tires planted and the chassis composed across rough terrain.
External reservoirs increase fluid capacity and help manage shock temperatures during prolonged or aggressive driving.
Large 2.5-inch shock bodies provide the capacity required for demanding applications where smaller factory-style dampers can struggle.
Upgraded upper control arms provide additional alignment capability and help support the geometry requirements of a lifted front suspension.
Rebuildable KING shocks provide long-term serviceability and allow the suspension to be re-valved or tuned as the vehicle evolves.
Together, these components create a balanced suspension package rather than a collection of unrelated upgrades.
Designed for Real-World Tundra Builds
This system is an excellent foundation for Tundras equipped or planned to be equipped with larger tires, aftermarket wheels, armor, recovery equipment, camping equipment, or other off-road accessories.
