ACC Heavy Duty, a division of Multi Parts Solutions, has launched ACC Fleet Solutions, a new program providing fleets experiencing chronic component failures with custom-engineered replacement parts at no up-front cost.
The company simultaneously announced the hiring of Brett Delp as commercial fleet sales manager to lead the initiative.
According to the company, the ACC Fleet Solutions program addresses a growing challenge facing commercial fleets: as economic pressures extend vehicle service life, aging trucks encounter part failures that existing aftermarket options cannot adequately solve.
Through the program, ACC says fleets identify problematic components, and ACC Heavy Duty’s engineering team develops improved replacement parts designed to outlast and outperform the original equipment. As a byproduct of this no-cost engineering service, ACC Heavy Duty is building a portfolio of superior aftermarket parts to support the commercial vehicle industry.

The program leverages the engineering infrastructure ACC Heavy Duty gained through its 2023 acquisition by Multi Parts Solutions. Founded in 1988, Multi Parts Solutions maintains a team of more than 110 professionals across three continents, with approximately 25 percent holding engineering degrees in mechanical, electrical, quality control and materials science disciplines. The company’s proprietary Sigma development process and $12 million investment in engineering and testing equipment enable rapid product development timelines, with most custom-engineered parts ready for fleet testing within six to 12 months.
“As we head into year four of a freight recession, fleets face unprecedented pressure on their bottom lines,” says Scott Robertson, vice president of sales for Multi Parts Solutions. “Vehicles are staying in service longer, which creates new failure patterns that OEM engineers — focused on future platforms — aren’t addressing. ACC Fleet Solutions enables fleets to eliminate persistently failing components and replace them with dependable, engineered solutions.”
The company states it has already completed pilot programs demonstrating the model’s effectiveness. Working with a major national fleet, ACC Heavy Duty says its engineers addressed chronic fuel pump failures by analyzing failed components, identifying design weaknesses and engineering an improved replacement. A separate project tackled premature turn signal switch failures — a legacy component design more than 40 years old — by engineering an updated version with improved reliability. Both solutions are now entering into production.
