Red Line Heavy ShockProof Gear Lube

Picking the right transmission fluid ensures the life and durability of your transmission, that’s why BAKER recommends a fully synthetic GL-5 rated gear weight oil of 75W-140.The Red Line Heavy ShockProof Gear Oil has a thickness greater than SAE 75W250, but has a unique low fluid friction like 75W90.

  • The Red Line Heavy ShockProof Gear Oil is recommended for heavily-loaded racing bikes. Not recommended for most synchro applications due to the product's extreme slipperiness.

      Baker the best

      Had a OD6 installed in the gear box and added the Red Line Heavy Gear . Did 500 klms , drained oil and nothing on the magnet or in the oil. CMR custom Harley Davidson Montreal did the work and I love it. When I shift no clunk not even a click everything just slides into gear. The Baker OD6 is fantastic .
