Control Arm Hardware Kit

The BMR Suspension Control Arm Hardware Kit (RH010) is a precision fastener set engineered for front lower control arm applications on GM G-Body vehicles from 1978–1987. This four-piece hardware kit supplies OEM-specification bolts critical to suspension geometry and steering response on classic muscle cars, street machines, and restoration projects where factory-correct assembly is non-negotiable.

Each bolt measures 4.63 inches in length with a 12mm diameter and 1.75 thread pitch—specifications matched to GM control arm mounting points on A-Body, G-Body, and related platform vehicles. The hex head design accommodates standard wrenches and impact sockets for field-expedient removal and installation. Steel construction with zinc oxide coating provides corrosion resistance in both dry climates and salt-air environments, critical for vehicles exposed to road salt, coastal humidity, or long-term storage. The 1.28 lb weight reflects a four-piece set, making this a complete bolt-down kit without requiring secondary sourcing.

Buyers performing control arm replacement, suspension rebuild, or restoration work on 1978–1987 Chevrolet Malibu, Pontiac Grand Am, Oldsmobile Cutlass, or Buick Regal platforms will recognize this kit as the direct replacement hardware for factory attachment points. Precision threading ensures clean assembly without cross-threading, while the zinc oxide finish maintains dimensional stability under vibration and thermal cycling. This is OEM-specification fastware, not universal hardware—fitment is verified for the G-Body platform and model year range cited.
