National type approval Germany (§ 22 StVZO)
Several Terrain Tamer suspension kits have received approval according to § 22 of the German Road Traffic Licensing Regulations (StVZO). The responsible authority is the Federal Motor Transport Authority (KBA) , the German type approval authority.
Requirements for approval
Retrofit chassis components must pass a series of rigorous tests:
- Endurance tests – proof of the long-term durability of the components.
- Load tests – Safe functioning under maximum payload/load.
- Driving tests – assessment of stability, driving behavior and safety in road traffic.
Significance of the approval
- Same legal status as OEM parts: After approval has been granted, the suspension kits bear the KBA mark and are legally treated like original parts in Germany.
- No additional approval required: Neither the installer nor the driver needs any further tests or certifications by third parties after installation.
- Vehicle-specific validity: The approval is tied to specific vehicles/models; each kit is certified for defined makes and models.
- Warranty remains valid: The installation of a KBA-approved Terrain Tamer kit does not void the manufacturer's warranty of a new vehicle.
An upper control arm is a crucial suspension component for 4WD vehicles , connecting the vehicle's frame to the steering knuckle. This component significantly improves handling , traction , and stability , especially in challenging terrain. Terrain Tamer upper control arms are specifically designed for 4x4 vehicles to maximize performance and reduce fatigue, while also enhancing strength and durability. They also offer adjustable caster settings, allowing you to fine-tune your 4x4's ride height .
Upper control arms ensure the tires stay on track while driving and off-road. They offer improved stability on varying road surfaces, as the suspension components can adjust flexibly without altering the wheels. They provide more support than conventional ball joints by reducing vibrations throughout your vehicle's 4WD suspension system. Thanks to their reinforced construction from high-quality materials such as steel or aluminum alloys, depending on the vehicle model, they ensure better maneuverability on uneven terrain while reducing tire wear, thus improving durability and performance.
Upper control arms offer outstanding stability and handling by minimizing vibrations from bumps and potholes. They also maximize traction off-road by controlling the wheel alignment angle. Furthermore, they offer adjustable caster settings, allowing you to fine-tune your 4x4 vehicle's ride height, resulting in improved performance and reduced fatigue while enhancing the system's strength and durability. Upper control arms enable improved off-road maneuverability and contribute to reduced tire wear and extended lifespan.
