For you RC crawler enthusiasts looking to improve your rig's performance, these brass wheel hex adapters are a game-changer. This is a 4-piece set that adds 3mm of width to each side, which really helps with stability and gives you a smoother drive on tricky terrain. The brass construction is key here - each adapter weighs about 7 grams, so that extra weight down low really improves your center of gravity and traction. They're designed specifically for the Axial SCX10 III Jeep JLU Wrangler (AXI03007) and the Capra 1.9 Unlimited Trail Buggy (AXI03004), so you know the fit is perfect. The package includes four stainless steel screw shafts (M3.5x2x11.8mm) so you have everything you need for installation. The widen design minimizes those extra gaps while increasing your wheel track noticeably. If you're looking to upgrade from the stock parts (which would be AXI232018), these brass hex adapters are one of those simple mods that make a real difference in how your crawler handles rough courses and maintains stability on inclines.
