Yukon YG NM205R-411R 4.11 Front Ring & Pinion for 04-15 Titan/Armada, 04-10 QX56

Vehicle Fitment

• 2004-2015 Nissan Titan (Front, 4WD, M205 differential)
• 2004-2015 Nissan Armada (Front, 4WD, M205 differential)
• 2008-2012 Nissan Pathfinder (V8, Front, 4WD, M205 differential)
• 2004-2010 Infiniti QX56 (Front, 4WD, M205 differential)

Fitment Notes

• Fits the M205 front differential only - not compatible with the R180 front differential used on V6-equipped Titan, Armada, Pathfinder, Xterra, or Frontier models
• Front and rear differential gear ratios must match on 4WD models; verify your rear axle ratio before ordering to avoid drivetrain damage

Features

• High-performance ring & pinion gear set engineered to OEM fitment specifications
• Advanced heat-treating process increases gear strength under high-torque conditions
• Precision-finished gear tooth surface reduces friction and operating heat
• High-grade steel construction on both ring and pinion for extended service life
• Designed and validated through Yukon's in-house engineering and quality-testing labs
• Quiet, smooth-running gear set suited for street, towing, and off-road use
• Supports larger tire upgrades by allowing a numerically higher (lower overall) gear ratio
• Matched and lapped ring and pinion set for consistent tooth contact pattern

Product Description

The Yukon YG NM205R-411R is a high-performance ring & pinion gear set built for the Nissan M205 front differential found in the Titan, Armada, Pathfinder V8, and Infiniti QX56. Manufactured to OEM fitment tolerances and finished using Yukon's advanced heat-treating and precision gear-cutting processes, this set is engineered to run quiet under normal driving while standing up to the added stress of towing, off-road use, and higher horsepower applications.

At a 4.11:1 ratio, this gear set is a popular upgrade for owners who have installed larger tires and want to restore lost acceleration, throttle response, and usable engine RPM. The ring and pinion are matched and lapped as a set, and Yukon's gear tooth surface finish is designed to minimize friction and heat buildup during extended use, whether on the street or the trail.

Because this is a front-differential gear set for a 4WD platform, it must be paired with a matching ratio in the rear M226 differential - running mismatched front and rear ratios can damage the transfer case. This set does not include an installation kit, bearings, seals, or a crush sleeve; a compatible master install kit is required to complete the swap.
