Introduction to the full-size Chevrolet and GMC pick-ups

The 1988 and later full-size (C and K model) Chevrolet and GMC pick-up trucks have a conventional front engine/rear wheel drive layout. Four-wheel drive (4WD) is available on some models.

The V6 and V8 engines equipped in these vehicles use Throttle Body Injection (TBI) on early models (1988 through 1995) or Central Sequential Fuel Injection (Central SFI) on late models (1996 through 2000). Power from the engine is transferred to either a four or five-speed manual or three or four-speed automatic transmission. A transfer case and driveshaft are used to drive the front driveaxles on 4WD models.

The suspension is independent at the front. On 2WD models, coi! springs are used at the front. On 4WD models, torsion bars are used instead of coil springs. The solid rear axle is suspended by leaf springs on all mod- must pass on to you to cover its labor and overhead costs. An added benefit
