Trail-Gear Assembled Third Members

5.0 out of 5 stars 2 Customer Reviews

Trail-Gear assembled third members are off-road strong! These units are built with all-new housings and internal parts and are delivered ready for you to drop into your axle. TG assembled third members feature top-quality ring and pinion gears, lockers, solid pinion spacers for long gear life, and they include triple-drilled flanges to cover common driveshaft patterns. The V6 units feature larger OEM-style V6 gear sets with longer pinion gear. Choose your locker style, case style, and gear ratio for off-road performance from Trail-Gear's selection of assembled third members.
