Polaris RZR Pro R SC +4.5" Rear Lightweight Drag Racing Trailing Arm Kit

Polaris RZR Pro R SC +4.5" Rear Lightweight Drag Racing Trailing Arm Kit

The AVID Racing Pro R SC+4.5 Trailing Arm Kit is engineered for the most powerful Polaris RZR Pro R drag and straight-line desert builds. Designed as the next evolution in rear suspension technology, this lightweight system eliminates the traditional toe link and rear knuckle, replacing them with a fully integrated trailing arm design for maximum strength and simplicity.

Key Features

• Unified trailing arm design — no toe link or rear knuckle required
• Ultra-lightweight — as low as 22 lbs per arm with billet carrier
• Optional billet 7075 radius rod kit with upgraded mounting plate
• 4130 Chromoly construction, precision TIG welded
• Four shock mounting positions for custom shock setup and driving preference
• 100% designed and built in-house by AVID Racing

Important Notes

Geometry: These arms do not use factory rear suspension geometry. Without a toe link, rear toe angle will vary as the suspension cycles. Toe is set to 0° at ride height.

Fitment: Radius rods must match the length of the trailing arms selected (-3, stock, or +3). Radius rod kits are sold separately.
