Adj Upper Ball Joint LH Mid GM Angled

The Adjustable Upper Ball Joint LH Mid GM Angled (ALL 56264) by ALLSTAR PERFORMANCE is a precision suspension component engineered for GM mid-size vehicles requiring a left-hand upper ball joint with angled geometry. This fastener-critical component connects the control arm to the steering knuckle, directly affecting steering response, wheel alignment, and suspension geometry. Whether you're restoring a classic GM platform, upgrading worn OEM joints, or building a custom suspension setup, this adjustable ball joint offers the fine-tuning capability that serious builders and mechanics demand for optimal handling characteristics.

The angled design of this upper ball joint accommodates specific GM suspension architectures and caster/camber requirements, allowing you to dial in precise wheel alignment without reliance on shim stacks or secondary correction methods. Its adjustable construction permits controlled changes to ball joint preload and geometry, a critical feature when working with modified control arms or custom chassis configurations. The compact 5.5 x 2.4 x 9.05-inch package and lightweight 1.1-pound design minimize unsprung weight while maintaining robust load capacity, a hallmark of ALLSTAR PERFORMANCE's race-proven engineering. High-quality materials and precision machining ensure consistent performance across heating and cooling cycles common in street and track applications.

This left-hand upper ball joint suits mechanics and fabricators working on mid-size GM platforms—including Chevelle, Cutlass, A-body, and similar chassis from the 1960s through 1980s—where precision suspension geometry directly impacts safety and performance. Installation requires proper alignment tools and expertise; it's ideal for shops performing complete front-end rebuilds or those transitioning to independent suspension geometry tuning. Compatibility is application-specific; verify your vehicle's suspension architecture and control arm configuration before ordering. Pair this joint with quality lower ball joints, control arm bushings, and a professional wheel alignment to achieve the handling refinement your build deserves.
