3502-0145U UDS 1350 Series Aluminum Tri Flange Yoke — 105mm / 110mm Dual Pattern, GM Applications
The 3502-0145U is a 1350 series 6061-T6 aluminum tri flange yoke manufactured by UDS for GM applications. It accommodates both a 105mm (4.134-inch) and a 110mm (4.331-inch) bolt circle spacing with 6 x 14mm bolt holes and a 14mm nose hole. The pilot diameter is 0.551 inches and the CJ-to-flat dimension is 3.000 inches. The hole-to-hole dimension is 3.580 inches for the 105mm pattern and 3.750 inches for the 110mm pattern.

When fitting the 3502-0145U, confirm the GM companion tri flange uses either a 105mm or 110mm bolt circle with 14mm bolt holes and a 0.551-inch pilot. The dual bolt pattern provides compatibility across two common GM tri-prong specifications — use the hole-to-hole dimension (3.580-inch for 105mm, 3.750-inch for 110mm) to confirm which pattern your application uses. The 14mm nose hole centers on the 14mm pilot feature.
The 3502-0145U is the 14mm bolt hole variant for GM applications. Compare it against the 3502-0161U, which uses 12mm bolt holes on the same 105mm/110mm dual pattern — the bolt hole diameter is the primary distinction between these two part numbers.
