The 1up Racing Blacked Out Battery Weight Set is exactly what you need to lower your car's center of gravity and shift the balance left on your Losi NASCAR, delivering improved stability and faster lap times than ever before!

Each stainless steel weight is precision-cut for a perfect fit in all Losi NASCAR variations and finished with a durable black coating for a slick appearance. The laser-etched 1up logo and weight rating make identification quick and easy.

The main 36g weight block fits directly under the battery, while the outer 14g block includes pre-cut double-sided tape for secure chassis installation. (Be sure to clean the chassis before applying for best adhesion.)
