OEM Alignment Camber Adjusting Eccentric

OEM Alignment Camber Adjusting Eccentric: Factory-Spec Precision for Wheel Alignment

When your vehicle's suspension geometry drifts out of spec — whether from worn hardware, a minor impact, or normal age — the alignment camber adjusting eccentric is one of the most targeted tools engineers have for bringing things back into line. Sometimes called an eccentric bolt or cam bolt, alignment camber adjusting eccentrics work by leveraging an offset (eccentric) profile on the bolt or washer to laterally displace the control arm or knuckle mounting point as the fastener is rotated, allowing a technician to dial in the exact camber angle the manufacturer intended — without modifying the suspension itself.

What sets OEM parts apart in this category is straightforward: these are the same components that left the assembly line with your vehicle. The OEM brand represents genuine, manufacturer-sourced hardware — engineered to the exact geometry, thread pitch, cam profile, and material specification that the vehicle's suspension system was designed around. An alignment camber adjusting eccentric features a circular device with an offset hole to allow for adjustment of alignment , and even minor deviations in that offset geometry can translate to misalignment after installation — making exact OEM tolerances critical.

Why Genuine OEM Eccentric Hardware Matters

Aftermarket camber bolts are widely available, but they are designed as universal or near-universal fits across multiple vehicle platforms. A genuine OEM eccentric, by contrast, is matched precisely to the suspension geometry of a specific model. The adjustment bolt includes a head, a neck, a lobe (or cam), and a threaded portion — with the head configured to provide a gripping surface for a tightening tool. Each of these dimensions is tightly controlled in an OEM part to ensure the cam's eccentricity produces the correct range of adjustment for that specific application.

It's also worth noting that many OEM eccentric bolts are single-use fasteners. Some of these parts cannot be reused or reinstalled once removed, as the clamping forces and torque applied during initial installation can deform the cam geometry or the fastener itself. Using a genuine OEM replacement ensures you're starting fresh with the correct hardware, not reusing a compromised component.

When to Replace Your Alignment Camber Adjusting Eccentric

These fasteners typically come into play during a professional wheel alignment, after a collision repair, following control arm or strut replacement, or any time a vehicle exhibits persistent pulling, off-center steering, or uneven tire wear that can't be resolved through conventional adjustment. The degree of eccentricity is designed to provide a range of toe and camber angles required to correct the position for a given suspension layout — adjustment is accomplished by loosening the spindle bolt, rotating the cam bolt head to move the spindle to a desired position, and then tightening to maintain that position.

Choosing a genuine OEM eccentric means the adjustment range will match what the vehicle's alignment specifications call for — no guesswork, no shimming, no compromise. For technicians and enthusiasts who demand factory-accurate results, OEM is the only standard worth working to.
