2006 GMC Sierra 1500 SLE1 Trim Level Overview

2006 GMC Sierra 1500 SLE1 Regular Cab 6.5 ft. SB

Blending a bit of luxury with pickup utility, the 2006 GMC Sierra 1500 SLE1 Regular Cab SB is a good fit for those who don't want to sacrifice comfort for functionality. The two-door, rear-wheel-drive pickup seats three in a front-row bench (bucket seats are optional) and comes with a 6.5-foot cargo bed equipped with tow hooks. The SLE1 Regular Cab upgrades from the SL1 with full power features, heated mirrors, remote entry, leather trim on the steering wheel and shifter, a compass and temperature readout, and upgraded cloth upholstery. These are in addition to already standard cruise control, a CD player with radio data, intermittent wipers, tilt and power steering, a front power outlet, and a tachometer. Satellite radio is optional.

The pickup is powered by a 4.8-liter, 285-hp V8 with 295 ft-lbs of torque at 4,000 RPM. This is matched to a 4-speed automatic. A 5.3-liter V8, available in a flex fuel version, is optional. An optional trailer hitch allows you to tow up to 8,400 pounds. The SLE1 rides on 17-inch chrome wheels with all-season tires.

Safety equipment includes 4-wheel ABS brakes with electronic brakeforce distribution, dual front airbags with passenger deactivation, a front stabilizer bar, and automatic headlights. The SLE1 adds standard foglights and an auto-dimming rearview mirror. However, this pickup earns average marks in crash tests. Traction control is available as an option, along with a locking rear differential and skid plates. New SLE1 options include OnStar, alloy wheels, and mirrors with turn signals.

There are many more options for the SLE1, including a power driver's seat with memory settings, a trip computer, and wheel-mounted audio controls.

2006 GMC Sierra 1500 SLE1 Extended Cab 4WD 8 ft. LB

Maybe it's the 19 extra inches of length and longer 8-foot cargo bed in the 2006 GMC Sierra 1500 SLE1 Extended Cab 4WD LB that drive its use of a beefy 5.3-liter, 295-hp V8 and 4-speed automatic.

2006 GMC Sierra 1500 SLE1 Crew Cab 5.8 ft. SB

The first thing you'll notice about the 2006 GMC Sierra 1500 SLE1 Crew Cab is its four full-size doors and extra legroom for backseat passengers. Legroom increases from 33.7 inches in the Extended Cabs to 39 inches in the Crew. What suffers is the cargo bed, which comes only in the 5.8-foot length. The 6.5- and 8-foot beds are not available with the Crew Cab. This rear-wheel-drive pickup also gets the strong 5.3-liter V8 that produces 285-hp and 335 ft-lbs of torque at 4,000 RPM.

In terms of safety, the pickup ranks average. Dual front airbags with passenger deactivation are standard, but no side curtain bags are available. Front disc and rear drum brakes are complemented by 4-wheel ABS and electronic brakeforce distribution. 17-inch wheels are standard, with the option to add 20-inch alloy ones.

2006 GMC Sierra 1500 SLE1 Extended Cab 8 ft. LB

An extra 19 inches in length and 14 inches in wheelbase permit a longer 8-foot cargo bed on the 2006 GMC Sierra 1500 SLE1 Extended Cab LB. The rear-wheel-drive pickup seats six in two rows that split-fold, and the front bench can be replaced with bucket seats. The longer bed requires a 295-hp, 5.3-liter V8 that delivers 335 ft-lbs of torque at 4,000 RPM and can tow 8,000 pounds. It is paired with a 4-speed automatic. The other engine option is a 285-hp, 4.8-liter V8. Fuel economy sits in the mid-teens.

The pickup bed comes with tow hooks and the option to add a trailer hitch. The SLE1 comes standard with full power features, remote entry, cruise control, heated mirrors, leather trim, a CD player, front power outlet and cupholders, tilt and power steering, a security system, a temperature readout and compass, and intermittent wipers.

2006 GMC Sierra 1500 SLE1 Extended Cab 4WD 6.5 ft. SB

The 2006 GMC Sierra 1500 SLE1 Extended Cab 4WD 6.5 SB is much like the 5.8 SB version in terms of standard equipment. The major difference is ten extra inches, which translates to a 6.5-foot bed. Inside, the two bench seats hold six passengers, though rear legroom is limited. Both benches split-fold. Though it has four doors, the rear doors are smaller and reverse-hinged. Fueling all this is a 4.8-liter, 285-hp V8 and 4-speed automatic transmission that get 15/19 mpg and can haul 10,000 pounds with the optional trailer hitch. Both a 5.3-liter V8 and a 6.0-liter V8 engine are available.

This trim features on-demand 4WD with both high- and low-range gearing for off-road utility. 8.4 inches of ground clearance, a locking center differential, and available off-road tires, 20-inch wheels, skid plates, and a locking rear differential improve performance. A front stabilizer bar, 4-wheel ABS brakes with electronic brakeforce distribution, dual front airbags, 17-inch wheels with all-season tires, foglights, and automatic headlights complete the safety equipment. Available options are Onstar and mirrors with turn signals. Stability control and side curtain airbags are not offered.

If you take this pickup out to play after working all day, it can be equipped with a power driver's seat, memory settings, leather upholstery, automatic climate control, wheel-mounted audio controls, and a trip computer. Privacy glass and a sliding rear window are other options.  

2006 GMC Sierra 1500 SLE1 Extended Cab 6.5 ft. SB

With ten more inches in overall length and wheelbase, the 2006 GMC Sierra 1500 SLE1 Extended Cab SB sports a 6.5-foot-long cargo bed. The half-ton pickup comes with four doors, though the rear ones open toward the back and in conjunction with the front doors. Two rows of split-folding bench seats fit six passengers, but front bucket seats can be substituted. Rear legroom is a tiny 33.7 inches. The rear-wheel-drive SLE1 sits on a short and long arm front and solid live axle rear suspension and rides on 17-inch steel wheels with all-season tires. Alloy wheels are optional, as are larger 20-inch wheels.

A 4.8-liter, 285-hp V8 and 4-speed automatic that get around 16/19 mpg can tow nearly 10,000 pounds. A more eco-friendly flex fuel 5.3-liter V8 is available, along with a powerful 345-hp 6.0-liter V8 and heavy duty suspension, for extra hauling capacity. Earning only three and four stars in frontal impact and rollover tests, the pickup comes standard with dual front airbags with passenger airbag sensors, 4-wheel ABS with electronic brakeforce distribution, and a front stabilizer bar. Also on hand are automatic headlights, foglights, and an auto-dimming rearview mirror. Adding more security are optional traction control, OnStar, skid plates, a locking rear differential, and mirrors with turn signals.

Driver comfort is taken care of by a full power setup, remote entry, cruise control, leather trim, and a CD player.

2006 GMC Sierra 1500 SLE1 Crew Cab 4WD 5.8 ft. SB

Doubling as both a family and work truck, the four-door 2006 GMC Sierra 1500 SLE1 Crew Cab 4WD seats six comfortably in two full-size rows, with split-folding benches and 39 inches of rear legroom. The 5.8-foot cargo bed comes with tow hooks, and an optional trailer hitch can tow up to 9,900 pounds with the 5.3-liter, 295-hp V8 and 4-speed automatic. This trim's low towing capacity is due to its on-demand four-wheel-drive system, which comes with a locking center differential and high- and low-range gearing. This means you can take the half-ton pickup off-road; optional skid plates, larger 20-inch wheels in place of the standard 17-inch, and a locking rear differential increase off-road confidence.

The pickup earns only three and four stars in crash tests, perhaps due to its lack of side impact and curtain airbags. A front stabilizer bar, 4-wheel ABS brakes with electronic brakeforce distribution, and dual front airbags are all standard. The truck sits on a short and long arm front and solid live axle rear suspension. Automatic headlights, foglights, and an auto-dimming rearview mirror are all standard. Paying extra gets you Onstar and mirrors with turn signals.

Full power features include remote entry, cruise control, a security system, and heated extendable mirrors. Leather trim on the steering wheel dresses up the interior, and leather seats can be added. A CD player comes with radio data. Wheel-mounted audio controls and satellite radio are optional. Other standard equipment includes tilt and power steering, a tachometer, a front power outlet, intermittent wipers, and a temperature display and compass. A power driver's seat with memory settings, automatic climate control, a trip computer, and sliding rear window can all be added.
