Jeep Wrangler TJ Differential Guard - Four Wheeler Magazine

Sean P. Holman Contributor

With stamped steel differential covers coming from the factory on most new 4x4s, diff protection is one of the first upgrades we recommend for severe trail duty. But maybe a heavy-duty nodular iron diff cover isn't in your budget? Finishlinewest has a new solution for those who need protection on a budget-its Stonehenge Series Boulder Bashers. These fabbed covers come with hardware and install over the top of your factory differential cover. The ring is laser-cut 1/4-inch steel, while the bash plates are made from 3/16-inch steel. They are designed to install easily (you don't even have to remove your factory cover) and not to interfere with your steering components.

We were invited up to the Finishlinewest compound to shoot an install of the Boulder Bashers on the company Wrangler TJ, but they are easily installed in any driveway.
