Components for Different Engine Builds

Not every performance engine component serves the same purpose. Camshafts and valvetrain parts can be selected for a particular engine setup, while forged pistons, connecting rods, crankshafts and bearings may be used when building or rebuilding an engine around specific performance requirements.

Other components, such as timing systems, oil pumps, gaskets, seals and engine hardware, help complete the engine assembly and support reliable operation.

For larger performance projects, engine components can also be combined with compatible cold-air intakes, throttle-body upgrades, intercoolers, performance exhaust systems, cooling upgrades and electronic tuning equipment.

Choose Components by Engine, Not Just Vehicle

Performance engine parts require particularly careful fitment. The same GMC model can have several engine options across different years and generations, meaning a component designed for one engine may not fit another.

Before purchasing, verify:

• GMC model
• Model year
• Engine size
• Engine code
• Generation
• Transmission
• 2WD, 4WD or AWD configuration where applicable
• Original part number
• Component specifications
• Manufacturer fitment information
