Thank you. You have rated this product.

Longacre's innovative Accutech SMi gauge is a 2-5/8" Stepper-Motor-style gauge that uses a small electronic motor that turns a fraction of a rotation to drive the pointer.

Much more precise than traditional mechanical gauges, many pro-racing teams are switching to Stepper-Motor gauges to improve accuracy. The gauges include ultra bright LED warning lights that are easily set by the user and include 2 total set-points to make sure you notice problems before they become disastrous.

The kit includes everything necessary for installation - heavily insulated wiring, soldered/heat-shrinked terminals, lights, and senders. Oil Temperature gauge reads from 100-340 F.

Other benefits include:

-2-5/8" gauge with molded polycarbonate/ABS case.

-Included electronic sensor drives the gauge - no oil or fuel in the driver s compartment for safety.

-Easy-to-Read thru-the-dial LED backlights and an illuminated pointer.

-Self testing - Pointers swing full scale and all LEDs light up when car is started

-Can be used with 12 and 16 Volt negative ground systems.


The Accutech line of gauges offer excellent value for track and street customers. Unlike most gauges, the sensors included with Accutech gauges are pre-wired and sealed against the weather. This is especially important for accurate readings from your sensors.


These are the gauges I use in my own track car after a long period of going through several other brands. I was really happy and relieved when I found Longacre's Accutech line of gauges; Excellent quality, very precise gauges that you can rely on at a very reasonable price.

A very clean installation example from our friend Erik Bruner of the SMI gauges in his NB. In his own words, the 2 5/8" gauges drop right into the vent hole after you remove the vent. It's as if they were made for that location:

Just wanted to thank you guys for the great stuff and great work done on my MX5 club yesterday. I could feel the difference in sound and performance right away! It drives and corners awesome now. Can't wait to tell my friends about you guys. I'll be keeping an eye on your web site for other goodies and events as well. Can't wait to try my new suspension out on a auto cross. Will definitely be trying it on some twisty roads this weekend. Just can't wipe that smile off my face when driving this car. Thanks again guys!
