Fitment Notes

• Front upper control arm kit for 1965-1970 GM B-Body applications.
• Sold as a pair with the bushings and ball joints pre-assembled.
• Designed to bolt into the stock upper-control-arm mounting locations without chassis modification.
• Compatible with stock spindles and drop spindles.
• Compatible with factory or aftermarket disc-brake systems.
• Compatible with QA1 single-adjustable, double-adjustable, and MOD Series Pro Coilover shocks.
• A professional front-end alignment is required after installation because the suspension geometry is changed.
• The factory-style coil spring remains in the lower control arm; unlike QA1 52700, this upper-arm kit does not itself require coilovers.
• 1965 Chevrolet Caprice is excluded because the Caprice nameplate began in 1966.
• No 2026 application is applicable because this is a 1965-1970 legacy GM B-Body application.

Features

• Street Performance 2.0 front upper control arm kit for GM B-Body vehicles.
• Lightweight tubular construction reduces unsprung weight.
• .109-inch-wall high-strength low-alloy steel tubing provides strength with reduced weight.
• 7075 aluminum-alloy upper cross shafts further reduce control-arm weight.
• Polyurethane bushings provide low-friction movement while controlling suspension deflection.
• Increased positive caster improves straight-line stability and tracking.
• QA1 Ultimate ball joints feature an integrated housing and rebuildable design.
• Low-friction ball joints support smooth suspension articulation.
• Integrated ball-joint housing provides increased structural strength.
• Double-shear lower shock-mount design supports clean coilover installation without adapters.
• Stamped-steel lower shock mount is designed for coilover-shock applications.
• Powder-coated finish helps protect against corrosion and wear.
• Bolt-in design uses the factory mounting locations.
• Pre-assembled construction simplifies installation.

Product Description

QA1 52701 is a Street Performance 2.0 front upper control arm kit designed for 1965-1970 GM B-Body vehicles. The lightweight tubular arms are engineered to improve handling and drivability while reducing unsprung weight compared with the original stamped components. The kit is designed for Chevrolet Bel Air, Biscayne, Caprice, Impala, and other compatible GM B-Body applications within the specified years.

The control arms use .109-inch-wall high-strength low-alloy steel tubing, 7075 aluminum upper cross shafts, polyurethane bushings, and QA1 Ultimate low-friction ball joints. Increased positive caster helps the vehicle track straighter and improves high-speed stability, while the integrated ball-joint housing provides a strong, rebuildable assembly. The powder-coated finish adds protection against corrosion and wear.

QA1 52701 is a bolt-in upper-control-arm upgrade that works with stock or drop spindles and factory or aftermarket disc-brake systems. The arms are compatible with QA1 single-adjustable, double-adjustable, and MOD Series Pro Coilover shocks. Because installation changes front suspension geometry, QA1 requires a professional front-end alignment after installation. The kit is supplied as a matched pair with bushings, ball joints, cross shafts, and required installation hardware.
