SD6 Series Walvoil SD6/2 Tie Rod Kit

Ambient temps from -40°F up to 140°F are covered, and the fluid itself can run anywhere from -4°F to 176°F with the standard Buna-N seals. So cold-weather operation is well within what this kit is built for. Just make sure your fluid viscosity stays in the acceptable range, which runs from 70 SSU minimum up to 1950 SSU maximum, since that matters more in cold starts than most folks expect.
