GMC C1500 Parts and GMC C1500 Accessories

What You Should Know about the GMC C1500

  • The C1500 was a full-sized pickup truck sold under the Chevrolet and GMC nameplates from 1960 until 1999 in the United States.

  • The "C" in the C1500 name indicates that the vehicle was a two-wheel drive. GMC also had a K1500, in which "K" meant that it was a four-wheel drive.

  • In 1967, the GMC C1500 came with a new, modern look as well as a nickname, "Action Line." In this model year, General Motors made revisions to the truck by adding GMC C1500 accessories that give comfort and convenience. While it came standard with leaf springs, its Chevrolet counterpart was built with a coil spring and a trailing arm in its rear suspension.

  • The model year 1967 was also the year of the small rear window. In 1968, however, this was replaced with a larger glass behind the vehicle. Another difference between the 1967 and 1968 GMC C1500 parts was that the latter had the addition of side-marker reflectors on its fenders.

  • Beginning 1968, the letters "GMC" were no longer embossed in the horizontal crossbar on the C1500's grille. The component's design was changed again in 1971, in which portions of the grille were painted over with black.

  • When the third generation was launched, the GMC introduced an all-new, clean-sheet redesign of the C1500 in 1972. While it had been developed beginning 1968, simulated assessments of the vehicle were only done on computers before the first prototype pickup was built for real-world testing. At the time of launch, the GMC C1500's design, particularly its cab, was considered revolutionary in appearance. This is because the design itself departed from the typical American pickup truck concept of that period.

  • The third-generation C1500 was officially known as the "rounded-line" generation. Nowadays, some refer to it as a "square body" because the truck appeared square-like compared to contemporary automotive design standards. The "rounded" exterior was fashioned by GM's design engineers. This was done in an effort to improve the truck's aerodynamics and gas mileage by using wind-tunnel technology to help sculpt the body.

  • Other design traits of the third generation were "double-wall" construction, sleek sculpted bodywork, flared secondary beltline, and an aerodynamic cab. The new traits then featured rounded doors that cut high into the roof. It also had a steeply raked windshield that had a hidden radio antenna embedded into the glass.

  • GMC C1500 Common Problems

    Sold as a full-sized pickup truck, the GMC C1500 was sold from 1995 to 1999 before being replaced by the GMC Sierra. When launched in 1995, it received a lot of upgrades and revisions to differentiate it from the third-generation Chevrolet C truck it was based on. Now with the vehicle out of production, used models are being sold in the market. For those who are looking to buy this truck or have just purchased one, be wary of some common problems involving GMC C1500 parts and performance.

    Service Brakes

    Many GMC C1500 owners found that their vehicle's anti-lock braking system (ABS) is not working properly. This failure was discovered after GMC dealers installed new brakes to the vehicle, but the new component didn't work properly. Instead of having this problem repaired elsewhere, GMC owners brought the vehicle back to the dealer who then found that there was a problem with the ABS.

    Other service brakes failure include the brake pressure module valve, brake anti-lock control unit, and brake pedal and linkage.


    Owners also reported that the steering speed sensor of their C1500 sometimes fails, causing the steering to suddenly jerk while turning at a corner. According to the drivers who had experienced this, the motion felt like the front wheels were hitting slippery ice.

    Steering also becomes loose while the truck is cruising on curved roads, causing drivers to lose control of their vehicle. Some had even come close to an accident, leading many concerned owners to complain to GMC dealers. However, what they only got was a response saying that since there was no recall from the manufacturer, there should be nothing to worry about.


    Some owners have problems seeing the road while driving, which is often caused by faulty windshield wipers. Drivers said that they don't always work, but they can be moved by hand, suggesting a short of some kind in the wiper's system. What's dangerous about this is when the wipers stop and the blades remain in the driver's line of sight, causing a major distraction. Other incidents include the wipers suddenly stopping during intermittent setting or even the component not stopping at all even after it's switched off.
