Wikipedia / RPO ZR2

Regular Production Option ZR2 is a special off-road/suspension package offered by General Motors on their mid-size pickup trucks and SUVs. It debuted in 1994 on the Chevrolet S-10 and the GMC Sonoma pickup trucks. The Sonoma ZR2 was known as ZR2 High-Rider. In 1996 it was expanded to the two-door Chevrolet Blazer and later offered on the Chevrolet Tracker. The ZR2 package was gradually phased out with the S-Series pickup and SUV lines. However, it has made a comeback as an option on the 2017 Chevrolet Colorado.
