Similar to Red Line's Heavy ShockProof, V-Twin Transmission Oil with ShockProof provides unequalled protection for both stock and aftermarket American V-Twin transmissions.

This product dampens transmission noise (reducing the notorious shifting ''clunk'' found in these gearboxes), dramatically reduces temperature, provides thicker oil films between gear teeth and completely resists throw-off. It is compatible with petroleum's and synthetics.

The viscosity characteristics allow the lubricant to resist throw off and provide a film thickness similar to a 75W250 grade, while providing the same low fluid friction as an SAE 75W90.
