Our Spider differential guard is like armor for your axle. Many of our customers have shared stories of their differential covers being peeled back and losing their differential fluid on some extreme trail. Or coming down hard on a boulder and now have differential and ring gear contact. And that’s why they and now ordering our Spider Rock Guards, but sadly after the fact. Other customers tell us point blank their vehicle will never be off road and that’s why they order one of our many candy color powder coatings. Regardless if you’re climbing a boulder on the Rubicon trail or a curb at 7-11 you will not be disappointed.
You may be somewhere in between these two scenarios. Whether you’re in the city with your family, on a weekend trail ride or at the beach, you will not be disappointed with the high quality performance and the rugged aesthetics of the Spider Differential Rock Guard. Our Spider may or may not work with aftermaket components you have already installed on your truck, write or call to be sure.
