What Thuren suspension does
Thuren suspension is an aftermarket suspension system designed for off-road vehicles, most commonly Jeeps and trucks. The company manufactures complete suspension kits that replace or upgrade your vehicle's factory suspension components — things like control arms, track bars, and sway bar links — to handle rough terrain, heavier loads, and more aggressive driving than stock suspension was built for.
Thuren systems are engineered to work together as a matched set rather than as individual bolt-on parts. This matters because suspension geometry — the angles and relationships between components — affects how your vehicle handles, where the wheels sit, and how much weight the system can carry. A Thuren kit accounts for all of that at once.
The company focuses on vehicles that see serious off-road use: Jeep Wranglers and Gladiators, Ford Broncos, and some truck platforms. If you're driving on pavement only, you won't need what Thuren builds. If you're rock crawling, desert running, or carrying heavy cargo off-road, their systems are built for that specific work.
Key Takeaways
- Thuren suspension kits replace multiple factory components as a complete system, not individual parts, to maintain proper suspension geometry for off-road use.
- Different Thuren kits are designed for different vehicles and different types of off-road driving — a rock crawling kit differs from a desert racing kit.
- Installation requires removing your factory suspension and bolting in the new components, which typically takes a shop several hours to a full day.
- Thuren systems cost more than individual aftermarket parts but are engineered to work together and often include warranty coverage.
- You will need a wheel alignment after installation because suspension geometry changes affect tire wear and handling.
How Thuren suspension components fit together
A Thuren kit includes control arms (the links that connect your wheel hub to the frame), track bars (which keep the axle centered under the vehicle), sway bar links, and sometimes bump stops or other geometry-specific parts. Each piece is manufactured to work with the others in the kit.
The reason this matters: if you mix a Thuren control arm with a factory track bar, the angles won't be right. Your wheels won't sit at the correct angle to the ground, your steering will feel off, and your tires will wear unevenly. Thuren kits avoid this by engineering everything together from the start.
Most Thuren kits also account for lift height. If you're running a 2-inch lift, the kit is designed for 2 inches. If you swap to a different lift later, the suspension geometry changes and you may need different Thuren components or a realignment.
What to expect during installation
Installation is not a backyard job for most people. You need a lift, specialized tools, and knowledge of suspension geometry. A shop will remove your factory suspension components, bolt in the Thuren parts, torque everything to spec, and then send you for a wheel alignment.
The work typically takes 4 to 8 hours depending on your vehicle and how much else needs to come apart. Some vehicles require additional work — removing skid plates, adjusting brake lines, or modifying brackets — which adds time and cost.
After installation, your vehicle will handle differently. The steering may feel heavier or lighter depending on the kit. The ride height changes. Braking and acceleration feel different because the suspension geometry affects weight transfer. This is normal and usually settles within a few hundred miles of driving.
Alignment and geometry after installation
A wheel alignment is not optional after a Thuren suspension install — it's necessary. The shop will measure your camber (the angle of the wheel), caster (the forward or backward tilt), and toe (whether the wheels point straight ahead). These angles change when you install new suspension, and if they're wrong, your tires wear fast and your vehicle pulls to one side.
Some shops include alignment in the installation cost. Others charge separately, usually $150 to $300. Ask before you commit to the work.
A good alignment shop will also check your suspension for binding or interference — places where components might rub or bind under compression. This is especially important if you've also added a lift or changed tire size.
Different Thuren kits for different uses
Thuren makes several suspension lines for different purposes. A rock crawling kit prioritizes articulation — the ability of each wheel to move up and down independently — and uses longer-travel components. A desert racing kit prioritizes speed and stability at high speeds, with stiffer geometry and different damping characteristics.
The kit you choose depends on how you actually use your vehicle. If you're mostly driving trails and occasional rocks, a mid-range kit works. If you're competing in rock crawling events, you need the crawling-specific kit. If you're running desert racing, that's a different animal entirely.
Thuren's website and spec sheets break down what each kit is designed for. Talk to the shop installing your kit about your actual use — they can tell you whether the kit you're considering is the right match.
Cost and warranty considerations
Thuren suspension kits are not cheap. A complete kit for a Jeep Wrangler or Gladiator typically runs $2,000 to $4,000 for parts alone, plus $500 to $1,500 in labor and alignment. Truck kits can cost more. This is higher than buying individual aftermarket parts, but you're paying for engineering and matched components.
Most Thuren kits come with a warranty that covers defects in materials and workmanship, usually for one to three years. The warranty typically does not cover damage from impact, abuse, or improper installation. Read the warranty terms before you buy.
Some shops offer their own warranty on the installation work separate from Thuren's parts warranty. Ask what's covered and for how long.
Maintenance after installation
Thuren suspension requires the same maintenance as any suspension system: regular inspection for loose bolts, worn bushings, and damage. Check your suspension every few months if you're driving off-road regularly, or at least once a year if you're mostly on pavement.
Bushings — the rubber or polyurethane pieces that absorb vibration — wear out over time. Thuren kits use quality bushings, but they're not permanent. Expect to replace them every 3 to 5 years depending on use. This is normal wear, not a defect.
Keep your alignment checked annually. Off-road driving can shift suspension geometry slightly, and catching it early prevents tire wear and handling problems.
Frequently Asked Questions
Can I install a Thuren kit myself?
Technically yes if you have a lift, torque wrench, alignment tools, and suspension knowledge. Practically, most people should have a shop do it. Improper installation can damage components, create safety issues, and void the warranty. A shop charges $500 to $1,500 in labor but gets it right the first time.
Will a Thuren suspension kit affect my vehicle's warranty?
Your factory warranty from the vehicle manufacturer may not cover suspension-related issues after you install aftermarket parts. Check your warranty documents or call the manufacturer. Thuren provides its own warranty on the components they sell, but that's separate from the factory coverage.
Do I need to change my shocks or springs when I install Thuren suspension?
Not always. Some Thuren kits work with factory shocks and springs, especially if you're not lifting the vehicle. Other kits require new shocks or springs to work properly. The kit documentation will specify what's needed. Your installer can also tell you whether your current shocks and springs are compatible.
How does a Thuren kit compare to other brands like Rubicon Express or Currie?
Each brand engineers suspension differently and targets different vehicles and uses. Thuren is known for rock crawling geometry and durability. Rubicon Express and Currie have their own strengths. Talk to shops that install all three and ask which they recommend for your specific vehicle and use case.
Will my vehicle sit higher after a Thuren install?
That depends on the kit. Some Thuren kits are designed to work with your factory ride height. Others are designed for a specific lift height — 2 inches, 3.5 inches, and so on. The kit you choose determines the final height. Your installer will tell you what to expect before the work starts.
