Rusty’s Long Travel Suspension Systems for Jeep
When short arms hit their limits, long travel suspension changes everything. Rusty’s Long Travel Jeep suspension systems are engineered to correct control arm geometry, increase articulation, and improve ride quality at higher lift heights. Whether you are building a dedicated rock crawler, an overland rig, or a high-speed trail Jeep, our long arm systems are designed to handle real abuse.
Every Rusty’s long arm system is built with heavy-duty materials, precision welding, and trail-proven design. From modular crossmembers to fully adjustable DOM control arms, these systems are designed to work as complete engineered packages rather than add-on brackets or partial fixes.
What Makes a Long Travel Suspension System Different?
Factory short control arms become steep and restrictive as lift height increases. This causes harsh ride quality, poor axle geometry, and excessive suspension binding. A long arm system repositions the control arm mounting points and increases arm length, allowing smoother suspension travel and improved traction.
- Improved suspension geometry at 4 inches of lift and above
- Reduced control arm angle and binding
- Increased articulation for rock crawling
- Better ride quality on-road and off-road
- Stronger crossmember and frame reinforcement
Available Long Arm Configurations
Radius Arm Systems
Radius arm setups provide a strong, simple design that balances daily driving comfort with serious trail performance. They use adjustable long arms built from DOM tubing and are ideal for drivers who want durability and predictable handling both on and off the road.
3-Link Long Arm Systems
3-Link systems increase articulation and are commonly chosen for dedicated trail rigs. By reducing binding and improving suspension movement, 3-Link setups are well suited for rock crawling and technical terrain.
4-Link Long Arm Systems
Standard and high-clearance 4-Link configurations improve stability and control under demanding off-road conditions. These systems are designed for drivers who want strong handling characteristics while maintaining trail capability.
Competition 4-Link Systems
Competition systems utilize 1.25-inch heim joints and reinforced mounting structures for race-level durability. These are built for high-speed desert use, JeepSpeed builds, and aggressive off-road driving where strength and precision matter most.
Built for Strength and Serviceability
Rusty’s long arm systems are constructed from heavy-duty 2-inch DOM tubing and feature rebuildable Flex Joints or heims depending on configuration. Many systems include modular 3-piece crossmembers for easier service and improved ground clearance.
Reinforcement brackets are designed to strengthen the unibody and distribute load properly. This prevents premature wear and ensures long-term durability even under extreme trail use.
Complete Long Arm Systems vs Long Arm Upgrades
Complete Long Travel Systems are engineered as full suspension packages and are designed to replace factory short arm setups. These systems include long arms, crossmembers, frame reinforcement, and supporting hardware necessary for proper installation.
Long Arm Upgrade Kits are designed for Jeeps already running 4 inches or more of lift. These upgrades allow you to convert an existing short arm suspension into a long arm configuration using your current springs and components. Upgrade kits focus on improving geometry and articulation and may not include track bars or additional suspension components.

Frequently Asked Questions
When should I upgrade to long arms?
If your Jeep has 4 inches or more of lift and you are experiencing harsh ride quality or limited articulation, a long arm system can significantly improve suspension performance.
Do long arm systems improve ride quality?
Yes. By reducing control arm angles and improving geometry, long arms typically provide smoother suspension movement and better road manners at higher lift heights.
Are long arm upgrades compatible with other brands?
Many Rusty’s long arm upgrade kits are designed to work with existing lift systems. Always verify compatibility with your specific setup before installation.
Are competition systems street friendly?
Competition systems prioritize strength and articulation. While some can be driven on the street, they are best suited for aggressive off-road use.
