Description

For Chevrolet Silverado and GMC Sierra (GMT800) with the 2003+ dashboard, also Tahoe, Yukon and Suburban with the same centre stack: the insert replaces the dash cubby and holds one 52 mm gauge flush in its face – on the Duramax typically EGT or boost.\n\n- Same outer shape as the OEM cubby: trim bezel off, cubby out, insert in; it sits on the OEM clips, crush ribs take up tolerances. Nothing is drilled.\n- The gauge sits flush in a guide tube with crush ribs.\n- The cable leaves the open back of the box behind the dashboard.\n- Variants for 45, 50 and 55 mm gauge depth.\n- Prints face-down on the bed: smooth visible side, no supports.

File the crush ribs if needed; check the hold on the OEM clips. Bore +0.4 mm, check with the test ring.

Dimensions

Material and temperature

Shaded location: PETG is sufficient, ASA is the more robust choice. PLA is unsuitable in a car – it starts to soften at about 55–60 °C.

Print orientation: Face (visible side) down on the bed, box pointing up.

Guide: PETG or ASA in a car?

Safety notice

The insert sits in the middle of the centre stack. Climate controls and radio must stay free; fuse the wiring and keep it off sharp edges. Install at your own risk. Never mount in an airbag deployment zone, never cover controls, never restrict the view. Follow the material and temperature advice. Add-ons may affect the type approval of the vehicle (§ 19 StVZO in Germany); keep edges in the head and knee area rounded (UN Regulation No. 21).

Not an original part. No affiliation with the vehicle manufacturers named; make and model names only indicate fitment.
