## Overview

Royal Purple Max Gear 75W-90 is a premium synthetic hypoid gear oil designed to protect and extend the life of heavily loaded gears in trucks, cars, and marine engines. Featuring proprietary Synerlec additive technology, it reduces friction and operating temperatures while maximizing horsepower and fuel efficiency. This set of three 1-quart bottles ensures long-lasting performance with superior corrosion protection and compatibility with limited-slip differentials.

## Description

Max Gear is recommended for use in truck and automotive front or rear differentials, manual transmissions and lower gear units of marine engines that specify use of an API GL-5 or GL-4 fluid. It is non-corrosive to soft yellow metals (brass, bronze, copper, etc.) and synchronizer safe. Specially designed to extend gear and bearing life, Max Gear provides superior corrosion protection over competing conventional and synthetic gear oils. Royal Purple engineered this ultra-tough, high performance automotive hypoid gear oil to provide maximum protection to heavily loaded gears while maximizing power throughout the drive train. Max Gear outperforms ordinary gear oils by combining the highest quality synthetic oils with Royal Purple’s proprietary Synerlec additive technology.

Great product, great prices.

### ⭐⭐⭐⭐⭐ Good quality oil for my gearbox and rearend
*by T***M on June 7, 2025*

I use Royal Purple Max Gear 75W-90 in both my AX15 manual transmission as it's "yellow-metal" safe for the bushings, and my Chrysler 8.25 rear end as this is an acceptable weight oil for it. Never had any problems with my transmission and since I'm rebuilding my rear-end I decided to spring for the quality stuff. Would recommend
