When it comes to improving the performance and capabilities of off-road vehicles, the steering system plays a crucial role. Two popular steering configurations that have gained significant attention in the off-roading community are crossover steering and high steer. In this article, we will explore the differences between these two systems and delve into their respective benefits and limitations. As an avid off-roader and user of both crossover steering and high steer, I will share my first-hand experience to provide you with valuable insights.
Crossover Steering
A. Definition and Functionality
Crossover steering is a steering setup that involves connecting the steering linkage from one side of the vehicle to the opposite side, effectively crossing over the frame. This configuration allows for better control and improved steering geometry, resulting in enhanced off-road performance.
B. Benefits
- Improved Steering Geometry
One of the primary advantages of crossover steering is the improvement in steering geometry. By crossing over the linkage, the angles at which the steering components operate are optimized, reducing bump steer and providing a smoother steering experience. This leads to enhanced stability and control while maneuvering over rough terrains.
- Increased Turning Radius
Crossover steering can also provide a larger turning radius compared to other steering setups. The increased range of motion allows for better maneuverability, particularly in tight spaces or when executing sharp turns off-road.
C. Limitations
- Potential for Bump Steer
Despite its advantages, crossover steering can introduce the potential for bump steer. Bump steer occurs when the vehicle’s suspension experiences vertical movement, causing the wheels to steer unintentionally. This issue is more likely to arise if the suspension is not properly set up or if modifications have been made without considering the effects on the steering system.
- Limited Steering Feedback
Another limitation of crossover steering is the reduced steering feedback. With the linkage crossing over the frame, the direct connection between the steering wheel and the front wheels is somewhat diminished. This can make it harder for the driver to feel the road and make precise adjustments while off-roading.
High Steer
A. Definition and Functionality
High steer, also known as “cross-over steering above the springs,” is a steering configuration that raises the steering linkage above the vehicle’s suspension components. This setup provides increased ground clearance and improves the overall steering control.
B. Benefits
- Improved Ground Clearance
One of the major advantages of high steer is the significant improvement in ground clearance. By moving the steering linkage above the suspension components, the risk of obstacles and rocks damaging the steering system is greatly reduced. This allows for smoother navigation over challenging terrains.
- Enhanced Steering Control
High steer offers superior steering control and responsiveness. With the linkage positioned above the suspension, there is less chance of interference with other components during articulation. This results in improved wheel articulation and better control over the vehicle’s trajectory.
C. Limitations
- Increased Complexity
The installation and maintenance of a high steer system can be more complex compared to other steering setups. Additional modifications may be required to accommodate the raised steering linkage, and careful attention must be paid to ensure proper alignment and compatibility with other components. This complexity can pose challenges for less-experienced off-road enthusiasts.
- Potential Interference Issues
While high steer provides benefits in terms of ground clearance and control, there is a possibility of interference with other vehicle components. This is particularly relevant when installing high steer on vehicles with limited space or tight clearances. Proper planning and careful installation are crucial to avoid any interference issues.

Frequently Asked Questions (FAQs)
What vehicles are most suitable for crossover steering?
Crossover steering can be implemented on a wide range of off-road vehicles, including trucks, SUVs, and Jeeps. However, it is particularly popular among rock crawlers and vehicles that undergo extreme suspension modifications.
Can high steer be installed on any vehicle?
High steer can be installed on various off-road vehicles, but it requires careful consideration of the vehicle’s suspension design, available space, and steering component compatibility. It is often favored by off-roaders who prioritize ground clearance and steering control.
Does crossover steering require modifications to the suspension system?
Crossover steering generally does not require extensive modifications to the suspension system. However, it is important to ensure proper alignment and address any potential clearance issues between the steering components and the suspension.
Are there any safety concerns with high steer?
When installed correctly, high steer does not pose significant safety concerns. However, it is essential to follow proper installation procedures and regularly inspect the system for any signs of wear or damage.
Which system is more expensive to install?
The cost of installation can vary depending on several factors, including the specific vehicle, aftermarket components used, and labor charges. However, in general, high steer systems tend to be more expensive due to the additional modifications and components required.
Final Thoughts
Both crossover steering and high steer offer unique advantages and considerations for off-road enthusiasts. Crossover steering excels in improving steering geometry and providing a larger turning radius, while high steer offers increased ground clearance and enhanced steering control. Ultimately, the choice between the two depends on individual preferences, the vehicle’s intended use, and the specific off-road challenges one is likely to encounter. By considering the benefits and limitations discussed in this article, you can make an informed decision and optimize your off-roading experience.
