HooLing Camber Alignment Tool 2-Pack — Adjustable Magnetic Caster Gauge, -5° to +5°

HooLing's 2-pack adjustable magnetic camber alignment tool is a compact, durable magnetic caster gauge that measures wheel caster from -5° to +5° and lets you quickly zero readings for accurate alignment checks.

Whether you're reassembling suspension parts after repairs or checking caster and camber before reinstalling wheels, these lightweight ABS gauges give repeatable readings without expensive shop equipment. Each tool features a strong magnetic base for stable attachment to hubs or brake rotors, a large calibration knob to set the bubble to zero, and a clearly marked scale to read small angle changes. Sold as a two-pack, they’re designed to fit both home mechanics and professional shops that need a portable, reliable method to verify wheel geometry.

How does the gauge help me check camber and caster quickly?

Set the instrument against the wheel hub or brake disc where its magnetic base holds it steady. Use the large adjustment knob to level the bubble and read the angle on the printed scale to detect changes in caster or camber within a five-degree range.

• Quick magnetic attachment to metal hubs and rotors for hands-free readings.
• Visible -5° to +5° scale for small adjustments and comparison checks.
• Large zeroing knob simplifies bubble calibration before each measurement.
• Pack of two lets you check both sides or replace one tool if needed.

Will this tool survive regular garage use?

The gauge is molded from premium ABS plastic that resists impacts, chemicals, and corrosion typically found in workshops. Its compact, lightweight construction balances portability with durability so it can be stowed in a toolbox or carried to a job site without taking up much room.

• Robust ABS body designed to resist wear and light drops.
• Magnetic base encapsulated for reliable holding power over time.
• Compact 4.9 x 1.2 x 0.8 inch footprint for easy storage.
• Silver finish hides dirt while remaining easy to clean.

How accurate are the readings and how should I prepare the surface?

Readings cover a precise range from -5° to +5°, with a fine horizontal bubble aiding in accurate zeroing. For the best results, wipe the magnetic base and wheel mounting surface clean and perform calibration on a level floor before taking measurements.

• Calibrate on a level surface to ensure consistent zeroing.
• Clean magnetic base and hub to avoid false readings caused by debris.
• Use steady placement on brake discs or wheel hubs for repeatability.
• Avoid extreme heat or prolonged sunlight exposure to protect the plastics.

What vehicles and scenarios is this tool suitable for?

The HooLing caster gauge works on a wide range of vehicles—from cars and SUVs to motorcycles, light trucks, and vans—making it useful for suspension repairs, tire diagnosis, and pre-reinstallation checks. Its non-specialized mounting means it adapts to many metal wheel surfaces where you need a quick angle reference.

• Compatible with cars, motorcycles, trucks, vans, and SUVs.
• Handy for home garage mechanics restoring strut positions after repairs.
• Useful for quick inspections before wheel reinstallation and road tests.
• Two-piece set provides convenience for bilateral checks or shop use.

Who is this for? If you perform regular suspension work, handle roadside adjustments, or maintain a small shop and want a low-cost, portable way to verify caster/camber changes, this HooLing 2-pack offers a practical solution. It’s also a good addition for enthusiasts who prefer to do precise DIY alignment checks at home without investing in bulky alignment racks.
