Ramp Travel Index (RTI)
Explanation: Ramp Travel Index (RTI) is a measurement used to determine the flexibility and articulation of a vehicle's suspension system. It is a way to quantify how well a vehicle can handle uneven terrain and obstacles by measuring the distance one wheel can travel up a ramp before another wheel loses contact with the ground. The higher the RTI score, the better the vehicle's suspension can handle off-road conditions.
Technical Explanation:
Common Symptoms:
- Poor off-road performance
- Limited wheel articulation
- Difficulty navigating obstacles
Diagnosing: To determine a vehicle's RTI score, a ramp is typically used to measure the distance one wheel can travel upwards while the other wheels remain on the ground. This can be done using specialized equipment or by visually observing the suspension's movement.
Common Repairs: Improving a vehicle's RTI score can be achieved through various modifications to the suspension system, such as installing longer shocks, adjustable control arms, or sway bar disconnects. Upgrading to larger tires with more aggressive tread patterns can also help improve off-road performance and articulation. Regular maintenance of the suspension components is essential to ensure optimal performance and longevity.
