Product details

Rear control arms are an essential suspension upgrade for your GM vehicle. Stock control arms often suffer from bushing deflection and rust, which can lead to traction loss and poor handling. Our tubular control arms provide a solution for both weekend cruisers and track enthusiasts. The polyurethane bushings outperform OEM rubber bushings, reducing traction loss and enhancing ride quality. These control arms are designed to minimize wheel hop, improve cornering, and ensure consistency on the track. They are compatible with both stock and aftermarket sway bars. Installation is straightforward and takes about 2 hours using the existing hardware. Detailed instructions are included. Upgrade GM rear suspension with UMI tubular control arms. Polyurethane bushings reduce traction loss, improve ride quality, and minimize wheel hop. Compatible with stock and aftermarket sway bars; 2-hour bolt-on installation. UMI GM rear control arms: tubular, poly bushings, reduces wheel hop.

BEFORE YOU ORDER

A few things to know.

How do I order these parts?

Add your exact parts and delivery details, then continue to payment. Eligible orders show the final parts, shipping and tax total and a PayPal button here after automatic checks. Freight, oversized, custom and uncertain items go to JuiceBuilt for a quote. You are charged only after approving PayPal; supplier orders are submitted separately after verified payment.

Does a part number guarantee vehicle fitment?

No. Product descriptions are supplied by the manufacturer. Check the manufacturer application information for your exact vehicle, engine and supporting modifications. Online checkout requires your exact-part fitment acknowledgment. Contact JuiceBuilt before ordering if you need fitment help.

Is the stock shown reserved for me?

No. Availability is a dated supplier snapshot. Inventory can change, and adding a part to your build does not reserve it. Availability and delivery are checked again before payment. A supplier order is confirmed separately after payment.

What about shipping?

Eligible standard-size parts orders with a parts subtotal of $100 or more receive free standard shipping. The minimum applies after coupons and other discounts.

The same $100 minimum applies to all brands, including Aerospace Components.

Oversized and freight items are excluded from free shipping at every subtotal, including carbon doors, hoods, trunks and similar large panels. Their shipping charge is quoted separately before payment.

Shipping for orders below $100 is calculated before payment.

Online checkout is initially available for US delivery addresses. For other countries, contact JuiceBuilt for a manual quote before payment.
