RED LINE SuperLight ShockProof Gear Oil 70w-75

RED LINE SYNTHETIC GEAR OILS are 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 base stocks, the only lubricants which can withstand the tremendous heat of modern jet engines, which makes our products provide excellent lubrication even under extreme conditions of high-loading and high-temperatures. The natural lubricity of the polyol esters provide excellent slipperiness which reduces the sliding friction in hypoid gears - reducing wear and significantly reducing 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 formulates more extreme-pressure protection into the gear oils than other petroleum and synthetic manufacturers which provides wear protection over a wider range of temperatures and performance conditions - ranging from high-torque and low-speed situations to very high-speed conditions with shock loading.

REDLINES unique ShockProof Gear Oils are recommended for heavily loaded racing differentials and gearboxes which see shockloading.
ShockProof contains a unique solid dispersion which cusions gear teeth to help prevent tooth breakage and allows the use of lower viscosities to give less drag and better shifting. Available as SuperLightWeight, LightWeight and Heavy.
SuperLight A unique product with the viscosity of 75W-90 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.

  • *Free shipping is available for UK Royal Mail, UPS Access Point™ (click & collect) and standard UK courier services (not express / priority / islands).
  • Courier surcharges mean we are unable to offer free "to the door" courier shipping from us in Cornwall up to Highlands / Grampian in Scotland - and because we send a lot of liquids, not every courier option is available to us. UPS Access Point™ (click & collect) is available as a free shipping option across Scotland, Wales and England, wherever there is a UPS Access Point™ Location.
  • Carriage charges are based on weight - please see our table of carriage costs for full details (although adding an item to your cart and viewing the calculated carriage is often easier!).
  • Priority shipping is also available.
