This is the factory-correct replacement bushing kit for those arms, sourced directly from Cognito, ensuring the pivot bushing interface is restored to spec without replacing the entire control arm. If your Cognito UCAs have grease fittings at the frame pivot, this is the kit. If your arms use the current press-in polyurethane bushing design, this kit does not apply.\u003c\/p\u003e\u003ch3\u003eConcierge Fitment Guarantee\u003c\/h3\u003e\u003cp\u003eEvery order is manually reviewed by our technicians to ensure 100% compatibility with your build before we ship.\u003c\/p\u003e\u003ch3\u003eEngineering Breakdown\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRestores\u003c\/strong\u003e the greaseable pivot bushing interface on older-generation Cognito SM Series Upper Control Arms to factory-correct specification — replacing worn or degraded pivot bushings that cause UCA slop, binding, and accelerated ball joint wear on high-mileage K2 2500HD\/3500HD applications running the earlier Cognito UCA design with grease fittings at the frame pivot.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEliminates\u003c\/strong\u003e the pivot bushing wear that manifests as steering wander, front-end clunking, and uneven tire wear on lifted and leveled K2 trucks — restoring the precise pivot geometry that the Cognito UCA design requires to maintain corrected ball joint angle and adequate droop travel at the elevated ride height.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDelivers\u003c\/strong\u003e a direct OEM-equivalent service replacement sourced from Cognito — correct bushing durometer, correct pivot bore diameter, correct grease channel geometry — without requiring removal and replacement of the entire upper control arm assembly.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThis bushing kit is compatible exclusively with older-generation Cognito Upper Control Arms that feature greaseable pivot bushings at the frame pivot point — identifiable by the presence of grease fittings (zerks) at the UCA frame mount.
