Ring & Pinion Yukon Gear & Axle YG C9.25-390

Yukon Gear & Axle ring and pinion set. This is a build component selected by SPECIFICATION rather than by a single vehicle application: match the frame size, flange, wheel size and A/R to your build. If you are not certain what your build needs, ask a tech before ordering.

What it does

The ring and pinion set the final drive ratio -- how many turns of the driveshaft it takes to turn the wheels once. A numerically higher ratio trades top speed for acceleration and towing grunt; a worn or howling set means the gear mesh has failed. A correctly set-up new set restores quiet drive and puts the engine in the rpm range you actually use.

How to choose

• Match the compressor and turbine wheel sizes to your power target and drive style
• Match the turbine housing A/R and flange to the manifold and downpipe you are running
• Confirm the oil and coolant feed arrangement matches your engine
• Check the part number against the component you are replacing

Fixes

• a howl or whine that changes with vehicle speed
• chipped or spalled gear teeth
• a regear for larger tyres or for towing
• a differential rebuild

What's included

• the ring and pinion at the ratio stated; install kit only where listed
