Lancia Delta Integrale

Drenth Gearboxes has developed a 5-speed dog engagement H-Pattern replacement gearbox for the Lancia Delta Integrale. While maintaining an OEM-identical exterior, the gearbox features a completely new internal design engineered for performance and durability.
The dog engagement system provides fast, precise shifting, making it perfectly suited for high-performance and competition use. The bellhousing has been structurally reinforced to increase strength, without changing the original external design. Combined with several detailed upgrades, including the replacement of high performance bearings, this gearbox is now capable of handling up to 550 Nm of torque.
