Magnetic Camber Alignment Gauge
Magnetic Camber Alignment Gauge
Wheel alignment at home.
Entry gauge. Full alignment system. Mount on cast iron hubs, brake rotors, or the ASWG001 wheel clamp. Zero the vial, read the bubble, record your angle. Camber and caster from +6° to -6° in 1/2° graduations. No shop, no batteries, no app.
What camber tells you.
Camber: Negative, Zero, Positive
Camber is the tilt of the wheel relative to vertical, viewed from the front. Negative camber tilts the top of the wheel inward toward the car. Positive tilts it outward. Zero is true vertical. The gauge reads the angle directly from the wheel face in 1/2° increments across the full +6° to -6° range.
How Camber Angle Affects Tire Wear
Negative camber loads the inside edge of the tire. Positive camber loads the outside edge. Either extreme causes uneven wear and reduces the contact patch under braking. Most passenger vehicles run slight negative camber from the factory. Use this gauge to confirm you are back within spec after suspension work.
How caster is measured.
Why You Zero the Vial Before Measuring
Caster requires two readings, not one. Turn the steering 20° inward and zero the calibration vial using the knob on the back of the gauge. Then sweep the wheel 20° outward. The amount the bubble deflects from zero is your caster reading. Without zeroing first, the second reading has no reference point.
What Caster Angle Does to the Car
Caster is the forward or rearward tilt of the steering axis viewed from the side. Positive caster tilts the axis rearward. It increases straight-line stability and returnability after a turn. Negative caster reduces steering effort but destabilizes the vehicle. Most road vehicles run 3° to 8° positive caster from the factory.

UNDERSTANDING CAMBER AND CASTER
The AutoSolo ASCGAL Magnetic Camber and Caster Gauge measures the two primary wheel alignment angles that determine how a tire contacts the road and how the steering self-centers. It is the entry-level gauge in the AutoSolo alignment system. Camber is the inward or outward tilt of the wheel relative to vertical, viewed from the front of the vehicle. Negative camber tilts the top of the wheel inward toward the chassis. Positive camber tilts it outward. Zero is true vertical. The gauge reads camber in 1/2° increments across a +6° to −6° range directly from the graduated vial. Caster is the forward or rearward angle of the steering axis when viewed from the side of the vehicle. Positive caster places the top of the steering axis rearward toward the driver, increasing steering returnability and straight-line stability. Caster requires a two-step sweep procedure: the steering is turned 20° inward, the calibration vial is zeroed with the adjustable knob on the back of the gauge, and the wheel is then swept 20° outward — the bubble deflection from zero is the caster reading. The ASCGAL mounts via strong magnets directly to cast iron hubs or brake rotors, and is also compatible with the AutoSolo ASWG001 Wheel Clamp adapter plate for rim-mounted readings that eliminate rotor-contact transfer error. No batteries, no app, no shop required. Arrives with a rigid carry case.
