Pontiac Grand Prix Parts & Accessories

Explore Pontiac Grand Prix parts for a handling project, brake repair or driveline service. Compare QA1, UMI and Ridetech suspension references with brake packages and axle components. Choose by your Grand Prix’s year and platform so the project starts with parts intended for the actual car.

Springs, Coil-Overs and Handling Packages

The selection includes spring references, adjustable dampers, control arms and larger handling or coil-over packages. Choose a targeted replacement for one service need or compare a coordinated package for a broader chassis project. Check the exact GM platform, intended ride height, spring specification and package contents; some handling kits explicitly exclude shocks.

Steering and Brake Choices

Ridetech steering-linkage, tie-rod and spindle components serve different installation scopes from a bushing repair. For Baer or Wilwood brake upgrades, compare the spindle, hub, hydraulic arrangement and wheel clearance as a system. Match each component to your Grand Prix chassis and any previous conversions before planning the installation.

Axle and Engine-Service References

Choose Yukon overhaul parts or Eaton differential assemblies according to the axle job: service an existing unit or replace the specified assembly. Match the housing, spline count and ratio first. For an ignition refresh, Granatelli wire options distinguish engine and model-year applications, including supercharged 3.8L configurations. Confirm the installed engine, terminal arrangement and wire routing before ordering.

Door Conversions and GXP Exhaust Projects

Vertical Doors listings identify separate 1979–1988, 1997–2003 and 2004–2008 Grand Prix applications. Confirm the exact body style, hinge configuration, supplied hardware and installation work for the selected conversion. A MagnaFlow cat-back listing names the 2005 Grand Prix GXP 5.3L V8; match the complete exhaust application and connection layout to your car rather than extending GXP coverage to a V6 model.
