Synthetic Gear Oil
Designed to provide the highest degree of protection and greatest efficiency for your drivetrain. Red Line
provides a complete line of drivetrain lubricants which are optimized for differential, transmission, or
transaxle use over a wide range of temperatures. Proper selection depends upon the manufacturers' requirements
and whether the application is for passenger automotive, commercial, or racing use. Red Line Gear Oils contain
polyol ester basestocks to provide excellent lubrication even under extreme conditions of high-loading and
high- temperatures--their natural lubricity provide excellent slipperiness which reduces the sliding friction
in hypoid gears to reduce wear and temperatures. The synthetic basestocks have a natural multigrade property,
so large amounts of unstable thickeners are not required to manufacture our gear oils, which means that Red
Line Gear Oils will provide a stable viscosity for even extended periods of use. Red Line also manufactures
gear oils which can be used in limited-slip differentials without the use of additional friction modifiers.
75W90
Our most popular gear oil, this is the preferred product in nearly all car and light truck differentials,
both conventional and limited-slip. 75W90 is preferred for most racing applications. It contains friction
modifier which is recommended for limited-slip units. 75W90 Gear Oil can be used in many transmissions and
transaxles; however, other Red Line lubricants have better frictional properties for rapid synchronization.
Exceeds API GL-5.
75W140
Our 75W140 gear oil is a GL-5 rated product recommended for street-driven road car differentials where that
viscosity is specified, providing excellent performance in both conventional and limited slip units. Popular
in late-model Ford truck rear differentials as well as many other common models.
80W140
Generally used in commercial trucks which will climb long, steep grades and some racing applications where power
is not critical. Generally 0.5% less efficient than 75W90. Can also be used in differentials and transmissions
where excessive noise is a problem and limited-slip differentials which vibrate excessively when turning a corner.
Exceeds API GL-5.
75W90 NS
This GL-5-type geal oil doesn't contain the friction modifiers for limited-slip hypoid differentials. This makes
the transmission synchronizers come to equal speeds more quickly, allowing faster shifting and much easier low-temperature
shifting. Can also be used in racing limited-slip differentials where weak spring design causes too much wheel spin.
75W140NS
A heavier product what works well over a wide range of loads and temperatures, This GL-5-type geal oil doesn't contain
the friction modifiers for limited-slip hypoid differentials. This makes the transmission synchronizers come to equal
speeds more quickly, allowing faster shifting and much easier low-temperature shifting. Can also be used in racing
limited-slip differentials where weak spring design causes too much wheel spin.
LightWeight Gear Oil
A friction-modified gear oil designed for use where 75W80 GL-5 gear oil is recommended (may be too slippery for some syncros).
Used in many motorcycle applications as an alternative to ShockProof types. It has excellent low-temperature flow which
allows easier shifting when cold and good synchro compatibility. May be used to obtain maximum power transfer in racing
differentials which do not see high temperatures.
Limited Slip Friction Modifier
Compatible with petroluem or synthetic gear oils, this product will significantly reduce the friction break-in of
differentials, reducing break-in temps for as much as 50 degrees F. Limited slip or positraction units will often chatter
without use of this product or a gear oil with a similar modifier, so add only enough to eliminate the chatter and avoid
making the plates or clutches too slippery.
Synthetic Shock Proof Gear Oil
A unique lubricant containing a suspension of solid microscopic particles as an extreme pressure agent--unique solid
dispersion which cushions gear teeth to help prevent tooth breakage and allows the use of lower viscosities. The viscosity
characteristics allow the lubricant to resist throwoff and provide a film thickness greater than an SAE 250 grade, with
the same low fluid friction as with our 80W140. Recommended for heavily-loaded racing differentials and transmissions,
Off Road racing and problem gearboxes. Offers a "best of both worlds" balance of relatively low drag and the utmost in
protection.
80W Motorcycle Gear Oil with ShockProof
New product designed for applications like two-stroke motocross bikes, shifter karts, the CRF 250 450 transmission. Used
where an 80W oil is called for, ShockProof's microscopic solid medium provides cushioning between gear teeth, while
maintaining lower drag Reduces the thinning effect from high temperatures. Provides the balanced slipperiness necessary
for consistent shifting and proper wet-clutch operation.
SuperLight ShockProof™
A unique product with the viscosity of 75W90 gear oil but lower internal friction similar to that of an ATF. Used when
temperatures are not high and when the maximum power output is required such as in stock car qualifying laps. Used in
low-power road racing transxles like Formula Vee and low-power SCCA Production classes (dog-ring type, generally not
sycro application where this product can be slippery).
LightWeight ShockProof™
A unique gear oil designed to lubricate racing transmissions and transaxles which see serious loads (not recommended
for most syncro-type transmissions). It has excellent low-temperature flow which allows easier shifting when cold.
May be used to obtain maximum power transfer in racing differentials which do not see high temperatures. Similar to a
75W140 gear oil, but with the lower internal friction of an SAE 30 motor oil. Used in most road-racing differentials
with moderate power and dogring racing transaxles.
Heavy ShockProof™
A unique lubricant containing a suspension of solid microscopic particles as an extreme pressure agent--unique solid
dispersion which cushions gear teeth to help prevent tooth breakage and allows the use of lower viscosities. Recommended
for heavily-loaded racing differentials and transmissions, Off Road racing and problem gearboxes. The viscosity characteristics
allow the lubricant to resist throwoff and provide a film thickness similar to a 75W250 grade, while providing the same low
fluid friction as an SAE 75W90.
