Originally introduced for the 2019 model year, the current 2023 GMC Sierra 1500 represents the fifth model year of Big Red’s fifth-generation full-size pickup truck. Today, GM Authority sources close to the matter tell us the manual tilt steering column for the 2023 Sierra 1500 is under constraint until further notice, resulting in some trucks being built with an upgraded tilt and telescoping column.
Beginning with February 27th production, the Tilt-Wheel (RPO code N33), or Manual Tilt Steering Column with a locking security feature, will be under constraint. This feature is normally equipped as standard on the base Pro trim level.
Meanwhile, the Manual Tilt and Telescoping Steering Column (RPO code N37) is standard on SLE, Elevation and SLT trims. The Power Rake and Telescoping Steering Column (RPO code N38) is optional on the SLT as part of the SLT Convenience Package (RPO code PCY), and standard on AT4, AT4X, Denali and Denali Ultimate trim levels.
In place of the N33 steering column, Pro units will be equipped with the aforementioned N37 Manual Tilt and Telescoping Steering Column instead, meaning that buyers will get an upgraded steering column.
It’s worth noting that since the beginning of production of the 2023 Sierra 1500, certain models – regardless of trim level – have been built without the electrical steering column lock (RPO code N06). Affected vehicles will be indicated as such with RPO code R7N.
Under the hood, the 2023 GMC Sierra 1500 is offered with a four engine options. These powerplant choices include the turbocharged 2.7L I4 L3B gasoline engine, atmospheric 5.3L V8 L84 gasoline engine, atmospheric 6.2L V8 L87 gasoline engine, and the 3.0L I6 LZ0 turbodiesel Duramax. The L3B is matched to the GM eight-speed automatic transmission, while the L84, the L87 and the LZ0 are mated to the GM 10-speed automatic transmission.
As for structure, the GMC Sierra 1500 rides on the GM T1 platform. Production takes place at the GM Fort Wayne plant in Indiana and GM Silao plant in Mexico.

Why does “N33” even exist? It’s less than desirable and economy of scale says “N37” should be standard,
Should be available on all models regardless
