Alternative to Penrite for steering box in General Discussion Posted November 8, 2018 · Edited November 8, 2018 by edinmass (see edit history) Yes, we added graphite to oil for our top fuel dragster in the cam boxes. Messy stuff(think like non cured rubber cement), worked well, and held up to running the strip with pure nitro. There are a lot of issues not covered here as far as steering boxes go. After a car sits baking in a hot garage in the summer and a freezing garage in the winter for forty, fifty, or sixty years, the lube in the box can turn to tar, or something worse. Then people com along and add new / modern lubricants on top of the old sludge type contents. The Lowe portion and bushings get no lubrication but the operator thinks they have taken car of the problem, and in reality all they have done is added to it. 95 percent of the total Restorations out there have not had their steering box apart, the same goes for the rear end.
