Description

The USA Standard Gear ZMBK478AWS is a comprehensive manual transmission bearing and seal overhaul kit engineered for the NSG370 transmission. It includes essential synchronizer rings, with the 5-6 speed rings featuring a special sprayed-on lining for enhanced performance. Additionally, the kit contains synchronizer rings for gears 1-4 which have 6 tabs; a note advises that if original rings have only 4 tabs, two tabs should be cut from the new rings. This kit is a regular grade type component, suitable for rebuilding worn transmission bearings. This bearing and seal kit is specifically designed for the 2012-2014 Jeep Wrangler models equipped with the NSG370 manual transmission (6-speed). Ensure your transmission code is NSG370 and it is a manual control type for proper fitment.
