Report – GM short on supply of its most popular pick-ups image

General Motors recently introduced the redesigned Chevrolet Silverado and GMC Sierra, a first since 2006, and now it is said the U.S. carmaker has trouble making enough of the most popular versions.

According to three people familiar with the effort, demand for the trucks is exceeding a supplier’s ability to produce certain drive train parts for the 5.3-liter V-8 engine, the most popular size, and GM is limiting how many dealers can order. One of the people said the issue could be resolved soon, another said it could take longer than a couple of months and they declined to name the supplier.

Silverado and Sierra are a centerpiece of GM’s wave of 18 new or redesigned models for the U.S. market. Full-size pickups generate $8,000 to $10,000 in gross profit each, and Detroit-based GM needs to resolve the shortage quickly to get the most out of its redesigned trucks before Ford brings out a new F-150 next year.

GM plans to offer the light-duty version of the new pickups with three engine options, a 4.3-liter V-6, 5.3-liter V-8 and 6.2-liter V-8. The smaller engine began production in August and the larger V-8 doesn’t arrive in showrooms until later this year. The 5.3-liter engine made up about 80 percent of the previous truck’s sales and was expected to be the same going forward.
