Designed as a direct-fit suspension component for compatible GM B-Body applications, this kit replaces the original rear upper control arms with a stronger tubular-steel design. It is engineered to provide reliable support for the rear axle while helping maintain proper suspension geometry during street driving, spirited use, and performance-oriented builds.\u003cbr\u003eThe UMI Performance 3661-B control arms feature durable steel construction with a black powder-coat finish for long-lasting protection and a clean, professional appearance. Tubular construction delivers a rigid, performance-focused alternative to conventional stamped control arms, helping support consistent suspension operation. The finish is well suited for restoration projects, handling upgrades, and custom muscle car applications where dependable components and a factory-compatible fit are important.\u003cbr\u003ePolyurethane bushings are included to provide a responsive connection between the control arms and suspension mounting points. These bushings are designed to help reduce unwanted flex compared with softer original-style materials while maintaining practical street-driving usability. The kit is intended for compatible 1965-1970 GM B-Body rear suspension applications and is supplied as a complete pair of rear upper control arms. Verify vehicle fitment and suspension configuration before installation. With its durable materials, performance-oriented construction, and application-specific design, the UMI Performance 3661-B is a practical choice for improving the strength and response of a classic GM B-Body rear suspension.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eApplication: Designed for compatible 1965-1970 GM B-Body rear suspension systems\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eComponent Type: Rear upper tubular control arm kit\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eConstruction: Durable steel tubular design\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eBushings: Polyurethane bushings included for responsive suspension control\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFinish: Protective black powder-coat finish\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eBrand and Part Number: UMI Performance 3661-B\u003c\/li\u003e\u003c\/ul\u003e","brand":"UMI PERFORMANCE","offers":[{"title":"Default Title","offer_id":48723105513694,"sku":"UMI3661-B","price":134.42,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0760\/7690\/8766\/files\/UMI3661-B.jpg?v=1787951216","url":"https:\/\/www.racingsupply.ca\/products\/umi-performance-3661-b-umi-performance-3661-b-rear-upper-tubular-control-arm-kit-for-1965-1970-gm-b-body","provider":"Racing Supply Co.","version":"1.0","type":"link"}
