Polaris RZR Pro R XC Rear Trailing Arm Kit – Toe Link Delete | AVID Racing

AVID Racing Polaris Pro R XC Trailing Arm Kit

The AVID Racing Pro R XC Rear Trailing Arm Kit is the next evolution in rear suspension design — engineered to deliver strength, simplicity, and real-world performance across any terrain.

Built from the foundation of our proven 80" Baja program, the XC system is designed for cross-country versatility — excelling in rocks, desert, sand, and aggressive trail conditions.

This is not a modified factory-style setup.
It’s a fully integrated rear suspension system that eliminates weak points and redefines how the Pro R puts power to the ground.

Performance Advantages

• Toe link delete design — eliminates a major factory failure point
• No rear knuckle — fully integrated trailing arm system for maximum strength
• Optimized camber curve and reduced wheel scrub for improved stability
• Simplified rear suspension architecture with fewer components and less maintenance
• 2" 4130 chromoly construction, precision TIG welded
• Designed and manufactured in-house by AVID Racing

Why No Toe Link?

By eliminating the toe link and rear knuckle, the XC system reduces complexity and increases durability.

Rear toe is set to 0° at ride height, and will naturally vary through suspension travel — a tradeoff that prioritizes strength, predictability, and reliability under load.

Fitment & Setup Notes

• Does not use factory rear suspension geometry
• AVID geometry targets ~3.5" ground clearance at full bump with 35” tires (Hole #1)
• Secondary mounting position available for increased clearance or smaller tires
• Straight radius rods required when using upper shock position (Hole #2)
• High clearance rods may contact at full droop in hole #2
• Changing shock length from our spec may negatively affect geometry, increasing wheel scrub and reducing built-in stability.

Radius Rod Options (Required)

This system requires radius rods matched to your trailing arm configuration. Each option is designed for a specific balance of strength, clearance, weight, and performance.

• 4130 Chromoly Straight Radius Rods
  Durable and reliable with a traditional straight design. Ideal for balanced builds prioritizing strength and longevity.
• Polaris Pro R XC Billet Straight Radius RodsLightweight and rigid, offering improved responsiveness and reduced weight for performance-focused builds.
  
• Polaris Pro R Billet High Clearance Radius Rods
  Designed for increased ground clearance in aggressive terrain. Best suited for rocks and technical riding conditions.
  
• Polaris Pro R Carbon Fiber Radius Rods
  Ultra-lightweight with excellent strength characteristics. Built for high-performance applications where reducing weight is a priority.

Radius Rod Plate Options

• Polaris Pro R Billet Plate (7075-T6)
  Precision machined for strength and rigidity. Ideal for high-performance and lightweight builds.
• Polaris Pro R 4130 Chromoly Race Plate
  Fully fabricated and assembled in-house. Designed for maximum durability and extreme-use applications.

What’s Included

• Complete rear trailing arm set
• All uniballs and rod ends
• All misalignment spacers and bushings
• Full titanium hardware kit for installation

Bottom Line

The AVID Pro R XC Trailing Arm Kit is the best all-around rear suspension solution for the Polaris Pro R — combining strength, simplified design, and geometry-driven performance across any terrain.
