Intended for applicable 1965-1970 GM B-Body Chevrolet Impala rear suspension applications. Confirm your vehicle uses the factory-style lower rear control arm mounting layout before ordering. Verify axle brackets, frame mounting points, bushings, and related suspension components. Cars with aftermarket rear suspension conversions, modified frames, or non-stock axles may require additional fitment checks. Existing bolts, bushings, and mounting hardware may need to be reused or purchased separately. Previous collision damage or chassis repairs can affect alignment. Professional installation and final suspension inspection are recommended.

Asked about this part

What vehicles does this lower rear control arm set fit?
This set is designed for compatible 1965–1970 GM B-Body Chevrolet Impala applications using the factory-style rear suspension layout.
Does the set include both left and right rear control arms?
Yes. The set includes both LH and RH lower rear control arms.
Are these control arms OE style?
Yes. They are built in an OE-style configuration to closely match the original rear lower control arm design and mounting arrangement.
What does GM B-Body mean?
GM B-Body refers to General Motors’ full-size rear-wheel-drive platform used on vehicles such as the Chevrolet Impala and other full-size GM models of the era.
Will these fit a 1965 Chevy Impala?
Yes, when used on a compatible factory-style 1965 Impala rear suspension setup.
Will they fit a 1970 Chevy Impala?
They are intended for compatible 1970 Chevrolet Impala applications as well. Always verify your existing suspension configuration before ordering.
Can these replace worn factory rear control arms?
Yes. They are suitable as replacement components for worn, bent, damaged, or heavily corroded original lower rear control arms.
Are these suitable for restoration projects?
Yes. The OE-style design makes them a good option for factory-style restorations, rebuilds, and classic Impala suspension repairs.
Are bushings included?
Included hardware and bushings may depend on the specific kit configuration. Check the product’s In the Box section to confirm exactly what is supplied.
What do the lower rear control arms do?
They help locate the rear axle, control fore-and-aft axle movement, and contribute to stable handling and proper rear suspension geometry.
Should both sides be replaced at the same time?
Replacing both LH and RH lower control arms together can help maintain consistent suspension performance and component condition.
Will these work with a stock rear axle?
They are intended primarily for compatible factory-style rear axle and suspension setups. Modified housings or custom suspension systems should be checked carefully before installation.
Can these be used with lowered suspension?
They may work with some lowered vehicles, but compatibility depends on the amount of lowering and any other suspension modifications.
Will they fit vehicles with air suspension or custom coilovers?
Not automatically. Custom air suspension, coilover conversions, or modified mounting points may require different or adjustable control arms.
Do I need an alignment after replacing rear control arms?
A traditional front-wheel alignment is not always required solely because of rear lower control arm replacement, but the rear suspension and axle positioning should still be inspected after installation.
Is professional installation recommended?
Yes. Rear control arms are critical suspension components, so professional installation is recommended if you are not experienced with classic GM suspension work.
What should I check before ordering?
Confirm the model year, GM B-Body application, rear suspension type, mounting points, and any existing modifications before purchasing.
