## Overview

Smilyeez BG Universal MGC is a cutting-edge gear supplement concentrate designed to enhance and protect both conventional and limited slip differentials. By improving lubricant film strength, thermal stability, and extreme pressure resistance, it reduces gearbox temperature and eliminates chatter noise. Compatible with all API GL-4 and GL-5 gear oils, it extends lubricant life, reduces wear, and ensures smooth, quiet operation across cars and trucks.

## Description

BG Universal MGC is designed to protect both conventional and limited slip differentials. It enhances lubricant film thickness and improves extreme pressure characteristics of any gear oil. It is a thermally stable, technically advanced supplement designed for use with any API GL-4 or GL-5 gear lubricant in conventional and limited slip applications. It smoothes and quiets operation of gears in the differential and fortifies the additives in gear lubricants. Excellent for use in manual transmissions and transfer cases to provide extra film strength, smooth shift action and corrosion protectionPROBLEM: Through normal operation, the bearings, input and output shaft gears and gear teeth in manual transmissions are subjected to intense stress and heat. Gear teeth will become pitted and worn. Synchronizer sleeves may become scored so that they do not move freely on the hubs.Full-time four wheel drive transfer cases will also often chatter loudly when turning because of too much friction. In many models, the chain will stretch, and chatter occurs because of the friction between the plates.Limited slip differentials are designed to transmit the major driving force to the wheel that has the most traction. However, when driving vehicles equipped with limited slip differentials, a loud chatter frequently occurs when the vehicle is turned. This problem is caused by stick-slipping between the plates because of too much friction.
