Description

This USA Standard Gear Transmission Bearing and Seal Kit is designed for rebuilding MR8 5-speed manual transmissions in various small/midsize cars from the '80s to early '90s. The kit includes transmission bearings, seals, and synchronizer rings for smooth shifting. It features an aluminum case, a 7-bolt cover over the 5th gears, and an external slave cylinder for easier installation. The multi-piece 1st-2nd gear synchro rings are designed for better engagement and less grinding. This kit is specifically for the MR8 transmission model, ensuring compatibility.
