The Tamiya 15374 JR Lightweight Center Chassis is built for hobbyists who want to refine their Mini 4WD PRO rigs. Molded from durable ABS resin, it achieves roughly a 10% weight reduction versus a conventional MS chassis while keeping rigidity for race use. The layout also promotes improved airflow to help control motor temperature during extended runs.
The chassis incorporates a revised turn switch system for the switch lever to simplify operation during events. Its profile and vents are arranged to encourage better air circulation, which helps maintain steady motor output when under load.
The Tamiya 15374 JR chassis accepts a wide range of Mini 4WD PRO upgrades, from reinforced gear covers to alternate motor mounts. Racers commonly pair it with higher torque or higher RPM motors, matched tyre compounds and fine-tuned gear ratios to suit either high speed straights or technical sections.
