Polaris RZR Turbo S Duner Trailing Arms | HCR Racing

Polaris RZR Turbo S rear suspension gains high-clearance geometry and reinforced construction with HCR Racing Duner trailing arms. The pair uses HCR Elite alloy, an internal angled catacomb structure, laser-cut sections and CNC-cut chromoly mounting points. A revised shock tower is designed to reduce compound leverage for a better motion ratio while retaining factory-wheel compatibility.

Key Features

• High-clearance rear trailing-arm design
• HCR Elite alloy is stated to provide 30% greater tensile and yield strength than 4130 chromoly
• Internal angled catacomb construction distributes load
• Laser-cut structure with CNC-cut chromoly mounting points
• Hand TIG-welded assembly
• Shock-tower design targets improved motion ratio
• Bolt-on installation
• Compatible with factory wheels

FAQ

What clearance advantage do these Turbo S trailing arms provide?

HCR uses a high-clearance arm profile to increase space beneath the rear suspension links.

What is HCR Elite alloy?

It is HCR’s proprietary material, which HCR states has 30% greater tensile and yield strength than 4130 chromoly.

How does the internal structure work?

HCR uses an angled catacomb design intended to distribute forces through the arm.

Will factory wheels fit?

Yes. HCR states that the trailing arms are compatible with factory wheels.

What is included?

The kit includes two rear trailing arms and installation hardware.

Are these stocked for immediate shipment?

HCR identifies its suspension kits as made to order, so lead time should be confirmed before purchase.

Why HCR Racing

HCR Racing combines proprietary alloy, internal reinforcement and application-specific shock geometry in its Duner suspension components. These arms are built as a direct Turbo S rear-suspension upgrade.
