Key Features

  • Flat washers included to spread clamp load across the bushing sleeve faces.
  • Direct bolt-on with no modifications, per UMI's product data.
  • UMI's grade designation for the kit is the metric 10.9 property class, and a supplier describes the bolts as 12 mm.
  • UMI publishes the kit as G-Body specific and direct bolt-on, which is written against factory pivot geometry.
  • Sort the new hardware by length before you begin, since the kit contains bolts for two different pivot positions.

Buick Regal Parts and Accessories

Buick Regal Parts and Accessories

Choose Buick Regal parts by generation, body and installed equipment. Classic brake conversions and later hood, window or pedal accessories need separate application references. Brake Upgrade and Chassis Scope For a complete brake kit, confirm exact chassis, spindle, axle and hydraulic requirements. Compare calipers, brackets, rotors, hoses and hardware supplied. Check wheel clearance with the manufacturer’s template against the actual wheel design. Wheel diameter alone does not establish spoke and barrel clearance. Body Accessories and Pedal Interfaces Hood protectors and window deflectors need exact body and front-end production coverage. Compare fascia mounting, in-channel or outside-mount installation and piece count. Pedal-control kits need the actual accelerator connector and vehicle application. Choose phone or display equipment by the required interface; response adjustment does not establish an engine-output gain. Choose Your Part Identify generation, body and engine. Conf...

Chevrolet El Camino Parts and Accessories

Chevrolet El Camino Parts and Accessories

Choose Chevrolet El Camino parts by generation, brake equipment and dashboard layout. Front and rear brake kits and digital instrument components have different mounting and companion-part requirements. Brake Kits by Chassis and Axle Listings distinguish later Malibu/El Camino/Monte Carlo/Regal brake applications from earlier GM chassis kits. Confirm exact year, front spindle and rear axle rather than extending a shared platform title. Compare front and rear kit contents separately. Check rotor size, hub or housing-end requirements and the actual wheels using the manufacturer’s clearance templates. Hydraulics and Instrument Installation Brake conversions need compatible hydraulic equipment and pedal-system requirements from the kit instructions. Record any axle or spindle changes for later service. A digital instrument display requires the specified dash application, wiring and signal inputs. Confirm sensors, harnesses and other installation pieces against the exact package contents...

Chevrolet Malibu Parts and Accessories

Chevrolet Malibu Parts and Accessories

Find Chevrolet Malibu parts by generation, body and Limited status. Different hood or fascia attachments and interior contours require exact application before comparing protection accessories. Front-End Protection by Generation Listings distinguish hood-mounted and fascia-mounted protectors across Malibu production. Match the actual hood, front-end shape and mounting rather than using finish or model name alone. Check Limited exclusions and exact body coverage in the manufacturer’s application. A shared production year does not establish identical front-end components. Floor Coverage and Chassis Details Map liner pieces to front, rear-row and cargo positions. Compare actual floor contours, console and retention with the supplied set. For brake or suspension work, use installed assembly details and engine or chassis application. Keep records of lowering components or conversions instead of transferring stock dimensions automatically. Choose Your Part Identify generation and Limited...

Chevrolet Monte Carlo Parts and Accessories

Chevrolet Monte Carlo Parts and Accessories

Choose Chevrolet Monte Carlo parts with generation and installed chassis identified. Classic brake kits, digital instruments and later electronic accessories have distinct application requirements. Classic Brake and Instrument Applications Baer listings identify specific later GM chassis kits; earlier platform titles still require exact Monte Carlo cross-coverage. Match spindles, rear axle and hydraulic requirements before choosing a conversion. Use wheel-clearance templates with the actual wheel profile and offset. A digital instrument display separately requires the correct dashboard mounting, signal inputs, sensors and wiring. Interior and Electronic Interfaces Universal mats need measured floor contours, retention and pedal clearance. Different Monte Carlo bodies do not establish interchangeable molded floor coverage. Pedal-response devices need an appropriate electronic accelerator system, connector and exact application. A broad model name spanning several generations does not...

GMC Caballero Parts and Accessories

GMC Caballero Parts and Accessories

Choose GMC Caballero brake-friction and shock components using the installed wheel ends and suspension. Compare operating requirements and mounting details before selecting a replacement. Front Friction and Rear Drum Service Identify front caliper and pad dimensions, then compare friction compounds for actual road or motorsport conditions. A compound name does not establish correct pad geometry. For rear shoes, compare the fitted drum and shoe dimensions. Check springs, adjusters and other service pieces against the package contents. Shock Position and Engine Accessories Match shocks by front/rear position, mounts and exact chassis application. Record ride-height or suspension changes with the service request. For a crankshaft damper, identify the actual engine, balance arrangement, pulley interface and manufacturer application. Keep any engine conversion explicit; a diesel-specific damper requires that exact installed-engine compatibility. Choose Your Part Identify actual front an...
