AUTO METER Tachometer Shock-Mount Adapter Strap 5" Pedestal Conversion — Race Shock Isolation

This mounting adapter is engineered to let racers convert 5-inch and several other tachometer housings to a pedestal configuration while adding shock isolation for rough-track conditions. It’s a direct-replacement strap and base kit designed to accept tachometers with a stepped case (approximately a 3 3/8" diameter section where the strap clamps). The assembly is straightforward and intended for motorsport applications only; it is not designed for street-legal installations.

What does this adapter do for my tachometer?

The 3209 strap secures the instrument in a pedestal mount and reduces vibration transfer to the gauge, protecting internal components during racing. It replaces the original mounting strap with a durable, race-focused assembly that keeps the tachometer stable under high-G conditions.

• Converts compatible tachometers to pedestal mounting
• Provides shock isolation to improve gauge longevity on rough tracks
• Direct-fit for 5" tachometers with the specified stepped case diameter

Which tachometers and sizes are compatible with this mount?

The 3209 is made to work as a direct replacement for most 5-inch pedestal tachometers that have the inch-step case (about 3 3/8" where the strap attaches). It can also adapt many 3 3/4" and 5" instruments to a pedestal mount, but always verify case diameter before ordering.

• Direct fit for 5" tachometers with the stepped case around 3 3/8"
• Can be used to convert many 3 3/4" and 5" instruments to pedestal style
• Includes base assembly kit for installation

How simple is the installation and what is included?

Installation is intended to be user-friendly for race teams and shops: the kit contains the base assembly and the mounting strap so you can replace an existing pedestal strap or convert a compatible tach to pedestal. Basic hand tools are typically all that’s required to transfer the instrument and secure the new mount.

• Includes complete base assembly kit for immediate installation
• No special tools required beyond typical hand tools
• Designed as a direct replacement—minimizing install time

Is this product suitable for street vehicles?

No. The 3209 mounting adapter is intended for competitive racing environments and is labeled RACE ONLY. It’s designed for performance and vibration isolation under track conditions rather than for street-legal applications or DOT compliance.

• Marked and engineered for race use only
• Not intended to meet street equipment regulations
• Best used with quality instruments for reliable race performance

Who is this for: The Auto Meter 3209 Tachometer Shock Mounting Adapter is for racers, builders, and shop technicians who need a robust pedestal conversion that isolates tachometer vibration and fits 5" stepped-case instruments. If you maintain competition vehicles or frequently work on race dashboards and want a quick, direct-fit mounting solution that includes the base assembly, this adapter is a practical addition to your toolkit. Confirm your instrument’s case diameter before purchasing to ensure compatibility.
