ShockProof™ Gear Oil

Red Line Synthetic ShockProof™ Gear Oil provides
unequalled protection for high-performance differentials
and transmissions which are heavily loaded or which see
shock-loading. This revolutionary lubricant is completelydifferent from conventional lubricant technology inseveral ways. The viscosity characteristics aresignificantly improved. Gear teeth need high viscosity athigh temperatures to prevent metal-to-metal contact anda low viscosity when cold to reduce fluid friction. The
ShockProof™ chemistry significantly reduces thethinning effect of high-temperatures. The Heavy can berated as a 75W250 Gear Oil, but has the lower internal
fluid friction of an SAE 75W90. The LightWeight can berated as a 75W140 Gear Oil, but has the lower internal
fluid friction of an SAE 30 motor oil. The SuperLight canbe rated as a 70W90 Gear Oil, but has the lower internal
fluid friction of an ATF. These ShockProof™ lubricants
provide much greater viscosity in the thin layers between
the gear teeth, but have very low internal fluid friction,
which means very little power loss for the protection

achieved. ShockProof™ Gear Oil has a 40% lower
coefficient of friction and 250% the load-carrying
capacity compared to conventional gear oils, whichmeans that metal-to-metal friction is greatly reduced.
Temperature reductions between 25°F - 75°F arecommon in circle track, road racing, and off-roadracing. Improved durability in high-performance use isthe primary benefit of the Heavy ShockProof™ andalong with the improved durability is an improvement inefficiency, but if further improvements in efficiency aredesired, and durability is not a major concern,
LightWeight and SuperLight ShockProof™ can beused. The cushioning effect of the ShockProof™
chemistry allows the use of one of the lighter
viscosities in many performance applications with little
sacrifice in durability. Red Line ShockProof™ can beused in conventional, limited-slip, or locker differentials.
Red Line ShockProof™ is designed for use incompetition differentials and transmissions.

The above graphs display the unique performancecharacteristics of the Red Line ShockProof chemistry.
The wear is one-tenth that of a petroleum product atmoderate loads, the coefficient of friction is nearly half.
The most significant improvement comes with the ability
to operate in extreme pressure regions with nearly
three-times the load which can be handled with aconventional petroleum gear oil and the wear obtained
The benefits of ShockProof™ Gear Oil are:is significantly lower at all pressures. Note how the Red
Line Synthetic 75W90 Gear Oil is a significant
improvement to the petroleum gear lubricants (mostother synthetics are not significantly better than theirpetroleum counter-parts.) All ShockProof™ viscosity
grades will provide similar metal-on-metal load-carrying
capabilities, the higher viscosities will resist squeeze out
better than the lower viscosities.

• Greatest extreme-pressure protection• Lowest coefficient of friction available• Reduces temperatures dramatically• Provides thicker oil films between gear teeth• Completely resists throw-off• Reduces metal-to-metal contact• Compatible with petroleums and synthetics• Low fluid friction to improve power transfer• Provides gear teeth shock loading protection• Reduces gear noise
