Thank you for contacting the Center for Auto Safety (CAS)
about your GM Suburban, Tahoe/Yukon, full-size C/K or Silverado/Sierra
pickup or Blazer/Jimmy sport utility vehicle. For years, GM had two Jimmys
and two Blazers - one full size and one mid-size. In 1993, the big GMC
Jimmy became the Yukon while the smaller S15 Jimmy became the only Jimmy.
In 1995, the big Chevrolet Blazer became the Tahoe while the smaller S10
Blazer became the only Blazer.
