Rancho is a popular brand of suspension, shocks, and more. Rancho was born in the 1950s in Long Beach, California, as Rancho Jeep Supply, and quickly grew into a thriving off-road and performance suspension components manufacturer. In 1985, Rancho launched what would later become its best-selling shock absorber: the RS5000. In 1990, Rancho was purchased by Tenneco Inc. and quickly expanded to include the world's first five-way adjustable shock absorber.
