Allstar Performance Plastigage

This compact kit gives mechanics and home enthusiasts a fast, non-invasive way to check bearing and journal clearances without micrometers or disassembly beyond cap removal. The color-coded strips flatten under load to indicate the clearance; matching the flattened width to the printed scale yields a quick numeric reading. Lightweight and vehicle-specific in fit, the set is ideal for inspections, rebuilds, and routine maintenance where space and time are limited.

How do I use Plastigage to measure bearing clearance?

Using Plastigage is straightforward: place a short piece across the journal, assemble the cap and torque to spec, then remove the cap and read the flattened width against the calibration scale. The material deforms proportionally to the gap, producing a direct, visual measurement without special tools. Clean all oil and debris before applying the strip for reliable results.

• Cut a 10–15 mm piece and lay it on the journal
• Install cap and tighten to required torque
• Remove cap and compare flattened width to the printed gauge
• Wipe surfaces clean after reading

What measurement range and accuracy does this kit cover?

This Allstar kit covers a narrow, precise band: 0.002–0.006 inches (0.025–0.076 mm), suitable for many engine and transmission clearances. The green/red color coding makes it easy to pick the correct strip type at a glance. For clearances outside this band, use a different Plastigage range to maintain measurement accuracy.

• Range: 0.002–0.006 in (0.025–0.076 mm)
• Supplied as twelve color-coded strips for repeated checks
• Intended for fine clearances—verify application compatibility

Can Plastigage be reused and how do I store it?

Plastigage strips are single-use items because the material permanently deforms when measuring. Store the unused strips flat in a cool, dry place away from solvents or extreme heat to keep them in good condition. Keep original packaging to prevent dust contamination and to maintain the printed calibration markings.

• Single-use only—do not attempt to reuse flattened strips
• Store sealed in original pack away from moisture and heat
• Handle with clean, dry hands to avoid contaminating strips

What should I check before choosing this Plastigage kit for my project?

Confirm that the 0.002–0.006 in range matches your engine or gearbox specification and that twelve strips provide enough tests for your job. Check torque values and surface cleanliness requirements for accurate readings. If you need a wider range or metric-only strips, select a different Allstar Plastigage product designed for that purpose.

• Verify manufacturer-specified clearance range first
• Ensure you have proper torque specs and clean surfaces
• Consider alternate ranges if your clearance falls outside this kit

This kit is compact and light—package dimensions are approximately 36.9 x 9.3 x 0.2 cm and the weight is 0.015 kg—manufactured in China and labeled for vehicle-specific fit where applicable. The straightforward measurement technique and clear printed scale help reduce teardown time during inspections.

Who is this for: Mechanics, engine builders, and DIY enthusiasts who need a quick, reliable way to verify tight bearing and journal clearances without specialized gauges. Ideal for routine checks, rebuilds, and troubleshooting when a fast, visual measurement is required.
