Rancho® – a popular brand of suspension, shocks and more worldwide – 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 absorbers. In 1990, Rancho was purchased by Tenneco Inc. and quickly expanded to include the world's first five-way adjustable shock absorber, allowing off-road enthusiasts to adjust the level of compression/rebound damping to suit their riding style, and launched the first "intelligent" shock.
