Rock Crawler, Street Lock wheels are proven strong on Moabs hard-core Terrain. A smooth rolled heavy-duty outer ring is welded 360 degrees to its rim making the wheels outer lip super strong to withstand the most severe off-road punishment against rocks and rough terrain. The rolled outer edge helps prevent tire sidewall damage at lower air pressure. Styled to look like the real thing, but unlike its counterpart, the Street Lock is legal for street use. Made in the USA. Center cap and lug nuts sold separately.
