Polaris RZR Pro R LT80" Rear Baja Long Travel Suspension Kit

Polaris RZR Pro R LT80" Rear Baja Suspension Kit | AVID Racing

The AVID Racing Pro R LT80" Rear Baja Kit is a complete, race-proven rear suspension system engineered to transform the Polaris RZR Pro R into a stable, predictable, high-speed desert platform.

Developed through real-world Baja testing and competition, this system goes beyond strength — it re-engineers rear suspension geometry to eliminate wheel scrub, improve shock performance, and deliver confidence at speed.

This is not a modified factory setup.
It’s a fully integrated, geometry-corrected rear suspension system built for serious drivers and race-level builds.

The AVID Difference: Geometry First

Most rear suspension upgrades focus on strength.
The LT80 Baja Kit was designed to correct how the Pro R behaves under load.

• Track width increased to 80 inches for maximum stability
• Factory-induced wheel scrub eliminated for smoother suspension travel
• Rear end remains stable and predictable through transitions and full droop
• Progressive leverage curve improves traction, damping consistency, and control

Performance Advantages

• Corrected rear geometry for reduced wheel scrub and improved tracking
• 80" width for increased stability at speed
• Relocated shock position for improved motion ratio and damping control
• Improved chassis balance through transitions, G-outs, and high-speed terrain
• Consistent traction and predictability under power

Construction & Engineering

• 4130 chromoly plate construction, precision TIG welded
• Radius rod plate available in 7075-T6 billet or fabricated chromoly
• Double shear frame mounting for maximum strength and zero deflection
• All mounts, tabs, and pivot points engineered as a complete system
  

What This Means on the Car

• Smoother tracking through rough terrain
• More control at high speed
• Improved shock performance and tuning range
• Greater durability under extreme use

What’s Included

• Complete rear trailing arm set
• All uniballs and rod ends
