Four kits. Two for the 2019–2026 UForce 1000 — one with in-cab heat control, which takes the place of the cup-holder tray on top of the dash, and one with a summer shutoff valve that keeps the tray — one for the UForce 600 (2021–2025) and the 2025+ UForce 800, and one for the UForce 500 (2015–2025) and 2015–2024 UForce 800. Every kit includes windshield defrost: 14,600 BTU of engine-coolant heat, all hardware and picture-rich instructions, shipped the same business day from Minnesota.
