Digital Calipers w/Case 0-6in ALL96411

OVERVIEW

Precision is the heartbeat of any high-performance air-cooled engine build, and the Allstar Performance Digital Calipers are an absolute necessity for the serious Volkswagen enthusiast. When you are assembling a Type 1 Mag case or shimming a high-revving valvetrain, guessing is never an option. These digital calipers provide the exactness required to measure critical components such as valve stem diameters, cylinder bore clearances, and shim thicknesses with a resolution of .001 inches. Whether you are working on a daily-driver Beetle or a weekend sand rail, having the ability to toggle instantly between Metric and SAE measurements allows you to speak the language of both German engineering and American performance parts without missing a beat.

Designed for the rugged environment of a busy VW shop, these calipers feature a large, easy-to-read LCD display that eliminates the eye strain often associated with traditional dial or vernier calipers. The versatility of this tool is unmatched; it effortlessly handles inside, outside, and depth measurements, making it the perfect companion for checking everything from brake pad thickness to the depth of a spark plug hole. The included protective plastic case ensures that your precision instrument stays calibrated and safe from the grease and grit of the garage. Don''t let a measurement error be the reason for an engine failureinvest in the tool that ensures every bolt and shim is exactly where it needs to be.

PRO TIPS

1. Always Zero Your Jaws Before Measuring

In the world of air-cooled VWs, a few thousandths of an inch can be the difference between a perfect deck height and a catastrophic piston-to-head collision. Before every measurement, ensure the caliper jaws are completely clean of any oil or metal shavings. Close the jaws firmly but gently and press the ''Zero'' button. This recalibrates the tool to its baseline, ensuring that your readings are consistently accurate throughout your entire engine assembly process. Even a tiny speck of dust can throw off your reading by .002 inches, which is enough to compromise your tolerances.

2. Mastering the Depth Gauge for Deck Height

One of the most frequent uses for these calipers in a VW shop is measuring the cylinder deck height. To get an accurate reading, use the depth rod at the end of the caliper. Place the base of the caliper flat across the top of the cylinder barrel and extend the rod down to the piston crown while the engine is at Top Dead Center (TDC). For the most reliable results, take three measurements at different points on the piston crown and average them. This ensures your compression ratio calculations are spot-on and your engine runs cool and efficient.

3. Proper Storage and Battery Care

Precision tools are sensitive to temperature swings and moisture, which are common in many home garages. Always wipe down your calipers with a lightly oiled cloth before returning them to their protective case to prevent any surface oxidation on the stainless steel. If you don''t plan on using the calipers for more than a month, it is a wise practice to remove the battery. This prevents any potential battery leakage from damaging the electronic internals of the LCD screen, ensuring that your Allstar Performance calipers are ready to work the next time you drop an engine for a rebuild.
