DETROIT (AP) — Fiat Chrysler’s Ram pickup unseated General Motors’ Chevrolet Silverado as the second-best selling vehicle in the U.S. during the first nine months of the year.

Experts say with a United Auto Workers strike underway that has shut down GM’s pickup factories, the Ram likely will beat the Silverado for the full year for the first time.

Company figures released Wednesday show the Ram led the Silverado by nearly 52,000 as of Sept. 30. So far this year, U.S. buyers snapped up 461,115 Rams, a 23% increase over the same time last year. GM sold 409,316 Silverados during the first nine months, down 3.6% from a year ago.

Ford’s F-Series pickup remained the most popular vehicle in America with 662,574 sold through September. That’s down 2.4% from a year ago.
