Buick Special Parts & Accessories

Explore Buick Special parts for brake restoration and chassis projects at Black Ops Auto Works. Compare hydraulic service components with applicable QA1 packages, UMI arms and Ridetech suspension choices. Identify the exact production and chassis before selecting parts for your Buick.

Hydraulic Brake Restoration

DFC Series 40 Special references include separate wheel-cylinder and hose applications. Match the full production range and correct axle or side, then compare bore, mounting and hydraulic connections. Drum, shoe and hardware choices must suit the installed assembly and any conversion.

Handling Packages and Spring Choices

For the listed 1964–1967 Special chassis, compare QA1 Level 2 HK22-GMA1 with shocks and HK32-GMA1 without shocks. The package choice affects how much of the suspension you are replacing and which existing components remain in the build. Review the complete current contents with the installer rather than assuming every handling kit includes the same dampers and springs.

Steering, Arms and Brake Conversions

Linkage, braces, sway bars and spindles require their exact mounting and companion components. A brake conversion also needs the complete hub, hydraulic and wheel-clearance arrangement. Review the current chassis and the planned system together with your installer.

Stock-Height Service or a Lowered Chassis

UMI factory-height spring references provide one path for a chassis refresh, while Ridetech StreetGRIP front lowering springs and the listed coilover systems serve different ride-height plans. Select springs around the actual engine weight and supported chassis. For coilovers, compare spring rate, adjustment and working travel as part of the full system.

The 1964–1967 and 1968–1972 handling packages are separate applications. Upper and lower arms, rear braces and sway bars can be selected for a staged project, or compared with a coordinated package for a larger rebuild. List the pieces already installed so a kit purchase does not duplicate compatible new components.

Frequently Asked Questions

Will one wheel-cylinder reference cover every Buick Special?

Match exact production, position, bore, mounting and hydraulic connections for the installed brakes.

Should I choose QA1 HK22-GMA1 or HK32-GMA1?

HK22-GMA1 is the listed 1964–1967 Level 2 configuration with shocks; HK32-GMA1 is the configuration without them. Choose according to the components you intend to replace or retain, then compare the exact current package contents and chassis requirements.

Can I retain the original drum brakes during a restoration?

A restoration can use replacement wheel cylinders, hoses and shoes when the installed drums and remaining assemblies meet service limits. Have the complete system inspected before choosing a focused hydraulic repair, a broader drum-brake rebuild or a disc conversion.

Can I select springs without reviewing dampers?

Confirm the compatible spring-and-damper combination, mounts and intended ride height together.

What should I check for a brake conversion?

Review the exact spindle, hub, hydraulics, wheel clearance and package contents required by the selected system.
