4.86 MOD Rear Pro Series Heavy Left Tube w/Tubes

The DIVERSIFIED MACHINE 4.86 MOD Rear Pro Series Heavy Left Tube with Tubes is a complete rear axle assembly engineered for high-performance off-road and hauling applications. This pro-series unit combines a 10-inch ring gear with a 4.86 gear ratio and magnesium center, delivering the gearing needed for demanding terrain, heavy loads, and recovery operations. The 60-inch wide configuration accommodates full-size truck platforms, while the heavy-duty construction handles sustained torque and shock loads typical of serious 4x4 work.

The 4.86 gear ratio provides aggressive low-end torque multiplication, essential for crawling over rocks, pulling through deep mud, and winching heavy objects. The magnesium center balances strength with weight reduction—critical in rear axle assemblies where unsprung mass directly affects suspension response and ride quality. Pro Series tubing specification indicates heavy-wall construction rated for extreme duty cycles. The left-hand tube orientation is designed to work with corresponding driveshaft and suspension geometry for proper fitment in specific truck models and custom builds.

This assembly suits builders, off-road competitors, and operators running dedicated expedition or recovery vehicles where stock axle gearing and strength fall short. Custom 4x4 fabrication shops, rock crawling teams, and serious overlanders rely on pro-series axle packages to handle repeated impacts, extreme angles, and sustained high torque that would exceed OEM component limits. Whether upgrading a trail rig, building a competition crawler, or setting up a remote expedition platform, the 4.86 ratio delivers the mechanical advantage needed when factory gearing compromises either traction or highway viability.

DIVERSIFIED MACHINE rear axle assemblies are recognized in the custom 4x4 and fabrication community for precision engineering and durability under extreme conditions. This pro-series configuration is suited for purpose-built vehicles where component reliability directly impacts safety and mission success. Verify truck model, suspension type, and driveshaft compatibility before ordering to ensure proper installation.
