This unique design of the P-lead adapter ensures proper spring pressure against the internal contact. It provides secure and stable alignment, and includes a post that prevents test leads from falling off. Complete set of three (3) adapters.

Designed specifically for aircraft magneto synchronization and engine timing. Eliminates all guesswork and provides a greater safety factor by creating perfect timing quickly and reliably.

A low-cost efficient gap setting tool for closing gaps on massive-electrode Aviation Spark Plugs. Compatible with all Champion, and Tempest Massive Electrode Spark Plugs.

Complete spark gapping kit includes Heavy Duty Gapper, Feeler Gauge, Gap Expansion Tool, and Electrode Erosion Gauge. Precisely sets gap to within .001" and checks to see if they are still serviceable.

This extension tube makes it easier to avoid obstructions when performing compression checks. Extends 8-1/2" to clear manifolds, harnesses, etc. For use with ATS model 2E and 2EM Compression Testers. 18MM threads fits most aviation engines.

The Magneto Internal Timing Kit is used to set the E-Gap on Bendix S-20, S-200, S-400, S-500, and S-1200 series aircraft and industrial magnetos. Instructions included.

Includes the ATS E50A Mag Synchronizer, E5A High Voltage cable tester, Mag Locks, and P-Lead adapters to perform magneto synchronization and ignition quality checks quickly and reliably.

Set of two (2) spline-type (internal hex) wrenches specifically designed to install and remove Lycoming Narrow Deck (ND), IO-390 and IO-580 round cylinder nuts. Sizes are 1/2" and 3/8" and both have a 1/2" square drive.

New 3882-series Cylinder Base Nut Wrenches feature a 12-point thin-walled hex head, and a 15" span for use with any Continental and newer Lycoming engines.

Factory refurbished model of our Spark Plug Cleaner & Tester features the latest in spark plug service equipment. It’s smart, functional styling and rugged construction makes it the perfect choice for anyone who needs to reliably and accurately test spark

High internal resistance in spark plugs is rapidly becoming a concern that many IA/AP's are beginning to recognize as the source of rough running engines and chronic magneto related problems.

The Hastings Ring-O-Matic Piston Ring Compressor Pliers incorporates a precision locking action for exact holding and release of piston ring bands.
