RED LINE Heavy ShockProof 75W250 Lubricant: Ultimate Protection for Sadev ST66
Neglecting the quality of lubrication in a dog-engagement gearbox or a racing transmission is a direct path to mechanical failure and exorbitant rebuild costs. Without RED LINE Heavy ShockProof oil, your gears endure direct metal-to-metal shocks that drastically reduce the lifespan of your Sadev gearbox or high-performance differentials.
Unique ShockProof Technology
RED LINE 75W250 gear oil contains a solid suspension agent that acts as a microscopic cushion between gear teeth. Skipping this product means losing the advantage of an ultra-resistant oil film that does not spin off under centrifugal force. This is exactly why Renault Sport specifies it for the ST66 gearbox, ensuring precise gear shifts even under critical operating temperatures.
Why your gearbox needs Red Line Heavy?
Enthusiasts of performance vehicles and track days often search for the ideal lubricant. Not choosing Red Line Heavy means risking:
- Premature wear of dogs and gears due to a lack of protective film.
- Excessive transmission noise and abnormal heat buildup in mechanical components.
- Mechanical breakage during aggressive gear changes in competitive racing.
