ARP strech gauge digital for con-rod bolts ARP 21112arp за Alfa Romeo 164 Sedan 2.0 Twin Spark (164A2) - 148 коня

Digital High End Dial Indicator from ARP for measuring the extension of expansion screws.

When fitting connecting rod bolts, the tightening torque is only of secondary importance. Much more important is the extension of the screw.

This stretch can be measured accurately with the ARP dial gauge.

ARP has taken accuracy to the next level with the introduction of a digital stretch gauge that measures to the ten-thousandth (0.0001-inch).

Accurate readings are made by opposing ball and pin probes centered on the bolt. A uniquely designed aluminum handle facilitates operation.

ALWAYS fit and tighten connecting rod bolts with sufficient ARP Ultra Torque Paste!
