Professional-Grade Power: The Volvo VNL Negative Battery Bar Advantage
This Volvo VNL Negative Battery Bar is engineered under our own FleetPro brand to strict commercial specifications. It features a heavy-duty conductive core designed to easily handle high-amperage cranking loads without dangerous overheating or voltage drops. The sleek black color-coding provides an immediate visual ground indicator, helping to prevent accidental and costly polarity reversals during maintenance. Note: Because this is a rigid bar, it is precision-drilled to perfectly match the factory battery tray spacing found on Volvo VNL, VN, and VNM models with four Group 31 batteries mounted in-line.
As we continue to build the largest inventory of commercial truck parts in Illinois, we prioritize electrical components that prevent "ghost" codes, weak grounds, and starting failures. This bar serves as a direct, high-quality replacement for expensive OEM numbers like Volvo 21107829 and aftermarket options like Dorman 242-5529N. Upgrading to a new, clean FleetPro bus bar restores the integrity of your grounding system and ensures maximum power delivery across your entire truck.
