This page covers the complete technical specifications for the 2026 Chevrolet Silverado 1500. For a plain-language tour of the truck, see our 2026 Silverado 1500 overview; for a side-by-side look at how the nine trims differ, see the full trim-levels comparison. Northeast Pennsylvania puts real demands on a half-ton: road salt and freeze-thaw through winter, steep grades on the runs north of the valley, and garages around Allentown and Nazareth built decades before trucks got this big. The numbers below are the ones that decide whether a Silverado fits your driveway, your trailer, and your work.

Engine Specifications

The 2026 Silverado 1500 offers four engines: a turbocharged four-cylinder, two V8s, and a turbo-diesel. The 2.7L TurboMax is standard on six of the nine trims; the 3.0L Duramax is the only diesel in the full-size light-duty class, per Chevrolet.

Engine	Horsepower	Torque	Transmission	Standard on
2.7L TurboMax I4 (turbo)	310 hp	430 lb-ft	8-speed automatic	WT, Custom, LT, RST, both Trail Boss models
5.3L EcoTec3 V8	355 hp	383 lb-ft	10-speed automatic	LTZ, High Country (available on Custom Trail Boss, LT, RST, LT Trail Boss)
6.2L EcoTec3 V8	420 hp	460 lb-ft	10-speed automatic	Available (RST 4x4, LT Trail Boss, LTZ 4x4, ZR2, HC 4x4)
3.0L Duramax Turbo-Diesel I6	305 hp	495 lb-ft	10-speed automatic	ZR2 (available on Custom Trail Boss, LT, RST, LT Trail Boss, LTZ, High Country)

Chevrolet rates the TurboMax's 430 lb-ft as best-in-class standard torque. The Duramax carries the highest torque of the lineup at 495 lb-ft. The 6.2L V8 is offered on Crew Cab configurations only.

Overall length	211 in to 242 in (varies by cab and bed)
Overall width	97.5 in with mirrors / 81.2 in without
Height	about 75.5 in
Wheelbase	126.5 in to 147.5 in (by cab and bed)
Ground clearance	7.9 in standard, 10.9 in Trail Boss, 11.2 in ZR2
Turning circle	about 46.3 ft (Crew Cab short bed)
Approach angle	33.5 degrees (ZR2)
Curb weight	4,410 lbs to 5,710 lbs (unloaded, by configuration)

Interior Dimensions

Capacity and Capability

Towing and payload both depend on engine, cab, bed, and drivetrain. The figures below are maximums when properly equipped; for the complete configuration-by-configuration breakdown, see our Silverado towing and payload guide.

• Maximum towing: up to 13,300 lbs (conventional hitch, Double Cab Standard Bed 2WD) with the 3.0L Duramax Turbo-Diesel, Max Trailering Package, and 20-inch wheels (Chevrolet).
• Towing by engine (conventional, properly equipped): 2.7L TurboMax up to 9,500 lbs; 5.3L V8 up to 11,400 lbs; 6.2L V8 up to 13,200 lbs; 3.0L Duramax up to 13,300 lbs. The minimum rating is 8,700 lbs.
• Maximum payload: 2,260 lbs, in the lightest configuration (Regular Cab, Long Bed, 2WD, 2.7L TurboMax).
• Bed lengths and cargo: short bed 5'8" (62.9 cu ft), standard bed 6'7" (71.7 cu ft), and long bed 8' (89.1 cu ft, which Chevrolet rates best-in-class). The bed carries 12 standard tie-downs rated at 500 lbs per corner.
• Bed features: the available Multi-Flex Tailgate offers six configurations, and the wheel-well width of 50.6 in lets a 4x8 sheet lie flat.

Wheels, Tires, and Brakes

• Standard 18-inch wheels on 265/65R18 all-season tires; 20-inch and 22-inch wheels are available depending on trim.
• The ZR2 runs 18-inch wheels wrapped in 33-inch Goodyear Wrangler Territory MT off-road tires.
• Four-wheel antilock brakes with ventilated front and rear discs, sized for the stop-and-go of Bethlehem traffic and loaded descents alike. A Performance Front Brake Kit is available, and the Stars & Steel special edition adds red Brembo brakes.

Fuel Economy and Range

Engine	EPA city	EPA highway	Combined
2.7L TurboMax	17 to 18 MPG	20 to 22 MPG	19 MPG
5.3L V8 (2WD)	16 MPG	20 MPG	18 MPG
6.2L V8	EPA figures vary by configuration
3.0L Duramax Turbo-Diesel	about 23 MPG	up to 28 MPG	about 25 MPG (2WD)

Chevrolet rates the Duramax's 28 MPG highway as best-in-class. EPA ratings vary by drivetrain; figures shown are for the gas engines in their most common configurations. Fuel tank capacity is 24.0 gallons, so the diesel's highway figure translates to a long cruising range between fills, an advantage on a haul down toward Slatington and back.

Safety and Compliance

Chevy Safety Assist is standard on every 2026 Silverado 1500, a six-feature package: Automatic Emergency Braking, Forward Collision Alert, Front Pedestrian Braking, Lane Keep Assist with Lane Departure Warning, Following Distance Indicator, and IntelliBeam automatic high beams. Also standard are a Rear Vision Camera, Tire Pressure Monitoring, StabiliTrak stability control, Teen Driver, Buckle to Drive, and OnStar Safety and Security.

Available driver-assistance features include Enhanced Automatic Emergency Braking, Lane Change Alert with Side Blind Zone Alert, Rear Cross Traffic Braking, Front and Rear Park Assist, HD Surround Vision, Trailer Side Blind Zone Alert, and Adaptive Cruise Control. The High Country offers Super Cruise hands-free driving that works while towing. J.D. Power named the Silverado America's #1 Full-Size Pickup for Initial Quality in 2025.

What These 2026 Silverado 1500 Numbers Mean in Practice

These tables answer one question at a time. Here is how the headline measurements translate into the everyday decisions of parking, fitting, and clearing.

Measurement	2026 Silverado 1500	What it means day to day
Width with mirrors	97.5 in	Wider than a typical 96-in single garage door; fold the mirrors (81.2 in at the body) to clear an older Bethlehem garage opening.
Overall length	211 to 242 in	A short-bed Crew Cab (about 232 in) fits a 20-ft (240-in) bay with inches to spare; the longest 242-in build will not.
Turning circle	about 46.3 ft	Plan wider U-turns and account for tight lots around Emmaus and Macungie town centers.
Ground clearance	7.9 to 11.2 in	Standard trims clear curbs and ramps; Trail Boss and ZR2 add height for ruts, snow banks, and trail obstacles.
Rear legroom (Crew)	43.4 in	Three adults ride comfortably in back; the Double Cab rear is tighter, and the Regular Cab seats two or three up front only.

If a tight garage is the constraint, a short-bed Crew Cab is the sweet spot for fit without giving up the full rear seat. If clearance for unplowed lanes around Whitehall and Nazareth matters more, a Trail Boss trim earns the extra inches.
