After retiring to stud full-time, he had a very successful career. He became the first All American Futurity winner to sire another winner when his daughter Easy Date won the All American Futurity in 1974. Easy Date was later named 1975 World Champion Quarter Running Horse. He also sired Pie In the Sky, the 1979 All American Futurity winner, and Mr Trucka Jet, the 1985 All American Futurity winner. More than 1,500 of his offspring earned their AQHA Race Register of Merit, and nine became World Champion Quarter Running Horses. Besides the horses already mentioned, the champions include My Easy Credit, Extra Easy, Easily Smashed, Easy Angel, Easy Move, and Megahertz. His foal Sunset Gallant Jet was the 1979 and 1980 AQHA High Point Cutting & Chariot Racing Co-Champion. At various points in time, Easy Jet has led the AQHA's lists of All-time leading sires of sires, All-time leading sires of Register of Merit qualifiers, All-time leading sires of stakes winners, and All-time leading broodmare sires. In March 2008, he still led the list of All-time leading sires of Quarter Horse racehorses by winners, and on the corresponding list ordered by earnings, he ranks fourth. As a broodmare sire, or maternal grandsire, of racehorses, Easy Jet led the All-time leading lists by winners in March 2008, and the same list ordered by earnings had him second. As of 2008, his offspring had earned over $26,000,000 on the racetrack. In total, he sired 2,507 foals in 25 years of breeding.
