1955 GMC 4×4 pickup

Classics, SUVs  /   /  By Jim Pickering

1955 was a split production year for GM trucks, with early production getting the previous year’s Advance Design body, and later trucks getting the all-new larger Task Force body. This truck is a rare one, as it’s an early ’55 Advance Design with a period NAPCO 4×4 conversion. Like all NAPCOs from this era, it started life as a two-wheel drive truck and was converted sometime later. And because 1955 was the first year GM used an external driveshaft in their trucks (rather than the enclosed torque tube used through 1954), it was also the first year a NAPCO 4×4 conversion could be fitted.

This truck’s running gear has been rebuilt, including the 4-speed manual transmission, transfer case, steering box, and both axles. It’s said to be completely restored and looks the part, although it does feature a number of upgrades from stock, including a larger 6-cylinder engine, wheels, tires, leather upholstery, and exotic African “Bubinga” wood in the truck bed.

The seller notes that this is likely one of the best NAPCO converted trucks available today, with no expenses spared on the restoration. Suffice to say you won’t be venturing out into the woods to cut firewood in this truck – but you’ll certainly look great at the next show.

A total of 5,319 1947-1955 GM Advance Design pickups have sold on eBay Motors in the past two years, with average prices ranging from $8k to $15k depending on options and condition. See this one’s listing here.

The comment about 1955 being the first year for the external driveshaft is not correct. The Advance Design running from 1947 1/2 to 1955 had external driveshafts on the 3/4 ton and larger models.
