Buick Gran Sport Parts & Accessories

Shop Buick Gran Sport parts for suspension projects, brake service and chassis restoration at Black Ops Auto Works. Explore QA1 handling packages, UMI springs and control arms, and Ridetech chassis components. Choose a coordinated setup for the exact year and equipment on your Buick.

QA1, UMI and Ridetech Suspension Choices

Compare the listed QA1 Level 2 handling packages with and without shocks for a coordinated chassis project. Choose the version with the dampers needed for the installation, or review the without-shocks package when separately selected compatible dampers are part of the plan. The exact kit’s vehicle coverage and contents determine which arms, springs and other components belong in the order.

Control Arms and Supporting Hardware

Upper and lower arms, trailing arms, chassis braces and spring or coilover brackets serve different jobs. Plan their compatibility as a system with the current mounts and suspension. Review bushings, adjustment ranges, supplied fasteners and alignment requirements for the selected combination.

Brake Service and Conversion Options

DFC hydraulic and friction references offer application-specific service choices. Wilwood front-brake kits are separate conversion projects requiring full spindle, hub, hydraulic and wheel-clearance coverage. Select the installed or planned brake system first, then choose the components and package contents required for the work.

Factory-Height Springs or a Lowered Setup

UMI factory-height spring packages offer a different stance plan from the separate lowering-spring references. Compare full front-and-rear packages with individual axle pairs before selecting the pieces for a supported chassis. Ridetech StreetGRIP front-spring references and separate coilover systems provide additional routes with their own engine, mount and damper requirements.

Plan the intended ride height around the existing wheel-and-tire package and required suspension travel. A spring purchase, adjustable-damper project and complete handling package cover different amounts of work. Choose that scope first, then coordinate compatible components with the installer.

Choose Your Part

• Identify year, chassis and installed suspension or brakes.
• Choose a coordinated handling setup or a focused service job.
• Compare complete applications, supplied components and installation scope.

Frequently Asked Questions

Should I order the QA1 handling kit with or without shocks?

Choose the with-shocks version when the project calls for the supplied compatible dampers. Compare the without-shocks version if suitable separately selected dampers are already included in the build plan. Check each kit’s full contents so a handling package does not duplicate parts or leave the required dampers unplanned.

Should I choose factory-height or lowering springs?

Start with the stance and service goal. Compare the UMI factory-height package for its stated stock-height application with lowering references for a planned ride-height change. Match the complete chassis and engine coverage, axle contents and damper requirements before ordering.

Can control arms be selected independently of other chassis parts?

Review the mounts, bushings, geometry and companion components for the complete suspension combination.

Does a Wilwood conversion fit any existing spindle?

Require explicit spindle, hub and hydraulic coverage for the exact kit and adequate wheel clearance.

What should I identify for brake maintenance?

Use the actual installed disc or drum system, correct axle and full part application, including any conversion details.
