VOLVO 20372039 Hinge Lower | Cab Door System Component



Heavy-Duty Door Hinge Mechanics
The 20372039 Hinge Lower precisely replaces VOLVO OEM reference 20372039. Constructed with cold-forged 41CrAlMo7-10 steel, this component maintains ±0.5mm manufacturing tolerance across all mounting surfaces. Quad-layer zinc-aluminum coating delivers 2,200+ hours neutral salt spray protection, specifically engineered for 1993-2021 model year FH/FM/FMX/NH series trucks. The reinforced pivot assembly supports ±4° angular compensation while handling door weights up to 150kg, with 14mm hardened pins ensuring structural integrity.
