Why Choose Broken Tractor:

• ✅ Covers both G-series panel groups — Cat revised the D3G–D5G instrument panel mid-run and kept this gauge — we list both groups and their serial books.
• ✅ Matched panel set — Oil temp, oil pressure and coolant gauges for the same dash so a tired panel is fixed in one order.
• ✅ Fast Shipping from a U.S.-Based Team — ready to ship from our U.S. warehouses.
