## Description

Red Line Oils 58404 Light Weight Shock Proof Gear Oil Red Line SHOCKPROOFTM GEAR OIL Recommended for heavily -loaded racing differentials and transmissions which see shock-loading. Red Line SHOCKPROOFTM GEAR OIL is a unique lubricant containing a suspension of solid microscopic particles as an extreme pressure agent. 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 offroad racing and problem gearboxes. 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

Review: I don't leave reviews at all but after using this product, I knew I had to leave a review. Got recommended by my tutor and read reviews about this product before purchasing, but was extremely surprised to confirm that it's legit. I drive a Mazda 3 (2015, BM). My Syncro's are quite worn and was having trouble shifting from 1st to 2nd and recently getting trouble shifting to 3rd, my 2nd gear cluster bearing was also noisy whilst cruising in 2nd, this is with replacing the transmission oil with Mazda's OEM transmission oil. After replacing the oil with this, it's truly a night and day difference. Feels like a new car, shifting is silky smooth and the cluster bearing is not noisy anymore! It does not completely solve the worn Syncro's but it's 200% better than what it was before. Highly recommend and would be buy again.
Review: NOTHING better than this stuff. Quality you would expect from REDLINE.. Protect those gears with this stuff.
