Twin I-Beam 2WD Pre-Runner Suspension Conversion Kit SCX10 III Overview
Transform your SCX10™ III into a scale 2WD desert racer with Pro-Line's Twin I-Beam Pre-Runner Suspension Kit! Inspired by the legendary trucks that defined off-road desert racing, this kit captures the long-travel durability, simplicity, and unmistakable geometry of true I-Beam suspension—scaled down for your 1/10 rig.
At the front, extended “I-beam” arms cross in an authentic X-pattern to control lateral movement, while radius arms tie back to the skid plate for rock-solid fore-aft stability. The setup even includes true swing set steering and a center-mounted radius arm, giving your SCX10™ III the realistic handling and suspension travel of a full-size desert truck.
Engineered for both performance and scale detail, the kit repositions key components for better balance and control, ensuring your rig doesn't just crawl—it rips.
