Eliminate the Clunk: Red Line V-Twin Transmission Oil with ShockProof®

Ensure the quietest, most protected gear changes possible in your high-performance V-Twin transmission with Red Line V-Twin Transmission Oil with ShockProof® (Part #42804), available now at Straight Six Imports. This unique full-synthetic lubricant, featuring Red Line's legendary ShockProof® technology, is engineered to provide unparalleled protection against extreme wear and sudden shock loads.

Based on the highly respected Heavy ShockProof® formula, this oil creates a fluid film thickness similar to a conventional 75W250 gear oil, while maintaining the low fluid friction of a 75W90. This revolutionary feature provides maximum protection without horsepower loss.

Key Features for V-Twin and High-Impact Transmissions:

• Dampens Transmission Noise: Specifically formulated to reduce the notorious shifting "clunk" and noise common in many V-Twin gearboxes (Harley-Davidson Evolution, Twin Cam, Milwaukee-Eight).

• Extreme Shock Protection: The suspended solid particles provide a "cushion" between gear teeth, minimizing metal-to-metal contact during severe shock loading and shifting under power.

• Reduces Operating Temperatures: Effectively transfers heat away from the gears, reducing operating temperatures by 25F to 75F for extended component life.

• Ultimate Film Strength: Provides a tenacious, non-throw-off film between gear teeth and bearings, ensuring protection even under the heaviest loads.

• Full-Synthetic Ester Base: Resistant to shear and thermal breakdown, ensuring consistent protection through long rides and harsh environments.

Upgrade your transmission’s durability and quiet its operation. Choose the unmatched protection of Red Line V-Twin Transmission Oil with ShockProof® (42804).
