Product Details

Royal Purple Max-Gear 80W-90 is a high-performance, full synthetic gear oil engineered to deliver maximum protection for heavily loaded gears while improving drivetrain efficiency. Formulated to meet API GL-5 and GL-4 specifications, it is suitable for use in truck, motor home/RV, and automotive front and rear differentials, manual transmissions, and lower gear units of marine engines.

Key Features:

  • Powered by Royal Purple's proprietary Synerlec additive technology, which increases oil film strength to 3–4 times that of comparable viscosity oils — dramatically reducing metal-to-metal contact and wear
  • Eliminates gear and bearing wear under severe conditions caused by high loads or sudden shock loading
  • Helps gears run smoother, quieter, and cooler — extending service life and reducing overhaul frequency
  • Non-corrosive to soft yellow metals (brass, bronze, copper) and synchronizer-safe for use in manual transmissions
  • Superior corrosion protection over conventional and competing synthetic gear oils
  • Exceptional temperature range performance: flash point of 325°F (163°C) and pour point of -60°F (-51°C)
  • Viscosity Index of 179 — outstanding viscosity stability across extreme temperature swings
  • All viscosities include hypoid friction modifiers — no additional limited-slip additives required for clutch or cone-type differentials

Royal Purple Max-Gear 80W-90 is available in a 5-gallon pail (MPN: 05302), ideal for fleet maintenance, shop use, or bulk fill applications. With a 4-Ball EP Weld Load of 315 kg and Load Wear Index of 66.0, it provides proven extreme-pressure protection verified by industry-standard ASTM testing.

I was able to order the part I needed and received it in a timely manner.

Easy purchase , and great price.

good so far

Good Products, and good service.

Easy site to use

Haven't fitted them to my truck, my size is not listed on the bag but they are adjustable to a point.

Easy

Ordered some parts the other day and was impressed, will see if it was a fluke.

This was the first time I'd shopped at autolicity. The site was easy to use and you guys had the best price by more than 20%. I'll be back the next time I need parts. Keep up the good work

Excellent transaction, received item very quickly and it was a lot cheaper than any other online retailer that I was able to find, could not even find cheaper on e bay.

The ordering process went really smoothly. Got my ordering info e-mailed smartly and was able to track the order easily. Looking forward to using my item as soon as it gets here!

Bought an Autometer Ultra lite 2 pyrometer and it looks great. Autoplicity has the best prices on their products and ships their products very quickly. I will definetly buy from them again.
