LOWERS OPERATING TEMPERATURE
BLUE DIAMOND SEVERE DUTY GEAR OIL improves thermal stability and friction reduction, protecting against varnish and sludge deposits

REDUCES WEAR
BLUE DIAMOND SEVERE DUTY GEAR OIL is infused with our patented FR3 Nano Technology which helps increase boundary layer protection and improves film strength for extra protection

REDUCES SHEARING
BLUE DIAMOND SEVERE DUTY GEAR OIL reduces shearing under severe duty applications, allowing the oil to remain in specifications for peak performance

IMPROVES OXIDATION STABILITY
BLUE DIAMOND SEVERE DUTY GEAR OIL was formulated specifically for severe duty applications, helping reduce breakdown, lowering oil consumption and extending gear oil change intervals

BLUE DIAMOND SEVERE DUTY GEAR OIL was formulated for severe duty applications. The gear oil additive formulas are based on 100% poly-alpha-olefin (PAO) Group IV and high-quality Group V synthetic oils. The infusion of our patented FR3 Nano Technology and high zinc additive package extends the performance and anti-wear protection to levels unmatched by any other gear oil on the market. BLUE DIAMOND heavy duty gear oil also provides increased oxidation and thermal stability, deposit and sludge prevention, reduced oil breakdown, high wear resistance and longer drain intervals. BLUE DIAMOND heavy duty gear oil is recommended as a gear oil for any demanding severe duty application, such as towing, hauling, challenging terrain driving, commercial use, utility vehicles, heavy equipment, tractors, motor homes, and other severe duty vehicles.

    5 out of 5 Works Great!

    The gear oil is an excellent product. My truck seems to roll longer after letting off the gas. My only complaint is no spout.

    5 out of 5 Excellent product !

    I have used the Hot Shot’s Blue Diamond Severe Duty Gear Oil on my Ram 3500 rear differential and am getting ready to change out the front diff this weekend. Use Hot Shot’s Secret exclusively on my Ram 3500. I even added the Franz Bypass Oil Filter. Love all of their products. Head and shoulders above the competition!

  4. Question

    Erik

    I”m considering using this when I change out the diff fluid for my 2019 Silverado 3500HD. This is mainly a tow vehicle all kinds of road conditions. Will this be ok to use?

      Your vehicle has the G80 locking differential. the G80 locking differential requires a 75w-90 gear oil. we currently offer our blue diamond S9 gear oil that will work for this application. You do NOT need a limited slip additive for this differential.
