TRZ Motorsports Race Dash Column Mount - Holley 12.3" Pro - 1 1/4" Column Tube (Other Columns) - H123-125
Holley 12.3" Pro Dash Mount for 1-1/4" Aftermarket Steering Columns
The TRZ Motorsports Race Dash Column Mount is engineered to securely support the large Holley 12.3" Pro digital dash on bigger aftermarket steering columns. This version is designed specifically for 1-1/4" diameter column tubes, making it the ideal choice for custom race builds, tube chassis cars, and performance applications not running TRZ 1-1/8" steering columns.
With a durable lightweight powdercoated bracket paired with a precision CNC-machined billet dash plate, this mount provides excellent vibration resistance, rigidity, and long-term durability - critical for high-power drag racing and hard-driven street/strip vehicles. It fits 1-1/8" or 1-1/4" column tubes depending on the drop-down selection but will NOT fit 1.5" steering columns.

Frequently Asked Questions
Can this mount be used with TRZ steering columns?
TRZ steering columns are 1-1/8" in diameter. This 1-1/4" version is intended for larger aftermarket columns, but the drop-down allows selection of the 1-1/8" size if needed.
Can this bracket be used with other Holley dash units?
No. This mount is specifically machined for the Holley 12.3" Pro display. Other Holley dashes require their own TRZ mounting solution.
