APPLICATION – Vintage Worm Steering Box Oil
Vintage Worm Steering Box Oil is suitable for steering boxes of vintage and classic vehicles with worm and sector or worm and roller mechanisms.
The very high viscosity makes this oil ideal for applications where reducing play and improving steering feel are essential.
It offers a solution for classic cars that suffer from heavy or sticky steering, and is particularly suitable for vehicles where conventional gear oils are too thin and cause leakage.
Thanks to its extra thick lubrication, this oil is perfect for traditional steering gear designs that require robust and stable lubrication.
