1/8" (3.175mm) Lite Steel - 135 pounds (61kg)
A great, cost effective alternative to aluminum, 1/8" lite steel will protect your drivetrain from damage. We recommend 1/8" lite steel where the application sees regular off-roading, yet very limited potential for regular sharp rock impacts. 1/8" lite steel is more susceptible to denting than 3/16" steel, yet this issue only presents itself during heavy single point impacts, like that of a large sharp rock. 1/8" lite steel requires powder coating or user-applied paint to prevent rust.
1/4" (6.35mm) Aluminum Alloy - 110 pounds (kg)
Strength without the weight. Our 5052 laser cut aluminum alloy has the same strength levels as our 3/16" steel, but at a faction of the weight. We recommend aluminum where the application sees regular off-roading, yet limited potential for dragging on hard surfaces like rocks. While 1/4" aluminum has the strength to handle heavy rock impacts, it is much more susceptible to galling than steel, when dragged over rocks. Galling results in what looks like fine aluminum shavings by the rock that was dragged down the plate. Another way of thinking about this is by first stating that aluminum has no problem at impacting an obstacle, it's what happens after impact that matters. After impact, if your driving style is to reassess the trail and choose a better line, aluminum is the right choice. If your driving style is to continue on the same line, as in rock crawling applications, we would recommend our 3/16" steel (Rock Armor) systems. Aluminum does not require prepping and repainting impact areas to prevent rust.
