Polaris Pro R Rear Differential Rebuild & Performance Service

Your Polaris Pro R rear differential is responsible for putting serious power to the ground in some of the most demanding off-road conditions imaginable.

High horsepower, aggressive acceleration, large tires, racing, desert riding, Baja, dunes, rocks, and hard recreational use can put enormous stress on the ring and pinion, gears, bearings, and other critical differential components.

When it's time to service your rear differential, don't settle for a basic teardown and rebuild.

Give your Polaris Pro R rear differential the complete CryoHeat performance treatment.

Our Polaris Pro R Rear Differential Rebuild & Performance Service goes beyond simply taking the differential apart and putting it back together.

Your differential is completely disassembled, inspected, cleaned, CryoHeat processed, precision-prepared, micropolished, and professionally rebuilt with careful attention to the critical details that affect drivetrain performance and durability.

What's Included in Your Polaris Pro R Rear Differential Service?

This is more than a basic rear differential rebuild.

Your Pro R rear differential goes through a detailed inspection, preparation, CryoHeat treatment, and professional rebuild process.

The service includes:

• Complete rear differential teardown and rebuild

• Detailed visual inspection

• Magnetic Particle Inspection of applicable components

• Vapor blasting of the differential cases

• CryoHeat processing of internal components

• Micropolishing of the gears

• Disc grinding the ring gear flat for zero runout

• Chamfering the ring and pinion gear teeth

• Precision shimming of the ring and pinion gears

• Professional reassembly

Replacement parts are not included in the base service price and will be an additional cost if required.

More Than a Standard Polaris Rear Differential Rebuild

Every Polaris Pro R rear differential is completely disassembled before the rebuild process begins.

Our technicians carefully clean and inspect the internal components for signs of wear, damage, or other issues that could affect the performance and reliability of the differential.

When applicable, components may undergo Magnetic Particle Inspection, a non-destructive testing process used to help identify potential cracks or discontinuities in ferrous-metal components.

The differential cases are also vapor blasted to thoroughly clean the surfaces and prepare the components for closer inspection and professional reassembly.

This detailed process allows us to evaluate the condition of your rear differential before it goes back together.

Precision Ring Gear Preparation

Proper ring gear preparation is an important part of a high-performance differential rebuild.

As part of the CryoHeat service, the ring gear is disc ground flat for zero runout.

The ring and pinion gear teeth are also chamfered as part of the preparation process.

These additional steps go beyond simply replacing worn components and reassembling the differential.

Every detail matters when you're building a drivetrain designed to handle the demands of a high-performance Polaris Pro R.

Precision Ring & Pinion Shimming

Proper ring and pinion setup is critical to differential performance.

During the rebuild process, the ring and pinion gears are precisely shimmed as part of the assembly and setup.

Proper attention to gear positioning and setup helps ensure that your rear differential is professionally assembled and prepared before it goes back into your Polaris Pro R.

The CryoHeat Performance Advantage

Once your differential components have been inspected and prepared, they receive CryoHeat processing.

CryoHeat's proprietary metal treatment process is designed to optimize metal components by addressing residual stress and improving the performance characteristics of critical drivetrain components.

CryoHeat processing is designed to promote:

• Improved wear resistance

• Greater dimensional stability

• Reduced residual stress

• Improved thermal characteristics

• Increased component longevity

We're not simply rebuilding your Polaris Pro R rear differential. We're giving critical internal components additional performance treatment before the differential goes back together.

Micropolishing for Smoother Gear Operation

The gears also receive micropolishing as part of the CryoHeat performance service.

Micropolishing improves the surface finish of critical gear components and is designed to reduce surface friction during operation.

A smoother surface finish can help promote:

• Reduced friction between critical gear surfaces

• Smoother operation

• Improved surface finish

• Reduced wear

• Increased component longevity

The combination of CryoHeat processing and micropolishing gives your Polaris Pro R rear differential more than a standard rebuild.

It gives critical drivetrain components additional performance treatment before professional reassembly.

Optional CryoHeat-Treated High-Performance Bearing Kit

If your rear differential needs replacement bearings, you also have the option to upgrade to a CryoHeat-treated high-performance bearing kit.

The bearing kit is available separately for $699.

The upgraded bearing kit is not required if your original bearings are in good condition. If your original bearings are damaged or require replacement, however, the CryoHeat-treated bearing kit provides an opportunity to upgrade the components going back into your differential.

The CryoHeat-treated high-performance bearing kit is sold separately and is an additional cost.

If replacement bearings are needed after inspection, our team can discuss the available options with you before adding them to your invoice.

What Happens If Your Differential Needs Additional Parts?

Every rear differential is inspected after teardown.

If we discover damaged gears, worn bearings, broken components, or other parts that require replacement, those components are not automatically included in the base service price.

Optional upgrades or replacement components may also carry an additional cost.

CryoHeat will contact you regarding additional parts that are required or recommended before they are added to your invoice.

We will communicate with you before moving forward with additional replacement parts or upgrades.

Don't Just Rebuild Your Rear Differential. Improve It.

A basic differential rebuild puts the assembly back together.

A CryoHeat Polaris Pro R Rear Differential Rebuild & Performance Service takes the process further.

Your differential receives:

Complete teardown.

Detailed inspection.

Magnetic Particle Inspection when applicable.

Vapor blasting.

CryoHeat processing.

Micropolishing of the gears.

Ring gear preparation for zero runout.

Chamfered ring and pinion gear teeth.

Precision ring and pinion shimming.

Professional reassembly.

And if replacement bearings are needed, you have the option to upgrade to a CryoHeat-treated high-performance bearing kit.

Whether you're racing, attacking Baja and desert terrain, riding dunes, building a high-horsepower Pro R, or simply demanding more from your machine, your rear differential deserves more than a basic rebuild.

Don't Just Rebuild It. Give It the CryoHeat Advantage.
