What Highline Warren makes

Highline Warren is a vertically integrated distributor and manufacturer of automotive aftermarket maintenance consumables, headquartered in Memphis, Tennessee. The company gives customers access to more than 30,000 products and over 400 national brands, and serves more than 10,000 customers across North America. Its distribution network reaches 95 percent of the U.S. population within two days at a company-stated 98.5 percent fill rate, and it ships roughly 1.9 million units of product every day.

On the manufacturing side, Highline Warren blends and fills automotive fluids at scale: motor oils and lubricants, windshield washer fluid, diesel exhaust fluid, and RV antifreeze. The company produces more than 200 million gallons of automotive fluids annually against a stated 450-million-gallon capacity, runs 25 blow-molding operations for its own bottles, and offers contract manufacturing and custom packaging to partners. It describes itself as the number one manufacturer of windshield washer fluid in the United States, and it is the exclusive U.S.-based blender and filler of Rain-X brand washer fluid under license. That combination of distribution and integrated fluid manufacturing is the company's stated point of difference: it owns much of the value chain from blending and bottling through to delivery to retailers, quick-lube operators, and installers.

Owned and licensed brands

Highline Warren sells national brands alongside a portfolio of owned and licensed brands. Prime Guard, a full-line automotive maintenance range spanning oil, antifreeze, wipers, and bulbs, is described as the company's fastest-growing owned brand. Other owned and licensed names include MAG 1 motor oils and lubricants, BlueDevil stop-leak and performance chemicals, Superior Automotive accessories (in the market since 1957), Sprayway glass and surface cleaners, PJ1 powersports specialty chemicals, LubriMatic, and the TruFlate and Amflo air-tool and accessory lines. Private-label and OEM-replacement programs round out the offering, supported by generations of blending and packaging experience carried over from the company's predecessor businesses.

Ownership and history

Highline Warren was established in 2020 through the combination of two long-standing aftermarket companies, Highline Aftermarket and Warren Distribution, under private-equity owner Pritzker Private Capital, which completed the acquisitions in November 2020. The lineage runs much deeper than the 2020 formation date. Warren Distribution was founded in 1922 and had become one of the largest private-label blenders and independent manufacturers of motor oil, lubricants, and automotive chemicals in North America, known for the MAG 1 brand. Highline Aftermarket itself was assembled through 2010s consolidation, including the simultaneous 2016 acquisition of the DYK and AAHC distribution groups, and predecessor businesses such as Levin's Auto Supply trace back to the 1920s.

The company remains a Pritzker Private Capital portfolio business and has stated a goal of growing to a 3 billion dollar business by 2028 through brand strength, acquisitions, and network expansion. Day-to-day leadership, per the company's own materials: Darcy Curran is chief executive officer, a role he has held since joining predecessor Highline Aftermarket in 2016 and continuing through the 2020 combination; Brad Moreschi is president and chief operating officer, named to that role in January 2025 after joining as chief financial officer in 2021; and Rebecca Fox is general counsel and chief compliance officer, previously general counsel of Warren Distribution.

Footprint and scale

Highline Warren operates 21 distribution and manufacturing facilities across North America, reported as 13 distribution centers and 9 manufacturing sites, with roughly 1.4 million square feet of manufacturing plant space. It employs more than 1,700 people. In July 2026 the company announced a planned acquisition of a 1.1-million-square-foot distribution and operations facility in McDonough, Georgia, to strengthen its East Coast logistics reach, a step toward the two-day national delivery standard it markets. The scale of the network, paired with in-house blending and bottling, is what lets the company run the fill rates and daily shipment volumes it publishes.

Known customers

Highline Warren serves more than 10,000 customers and describes itself as a strategic manufacturing partner to top North American retailers, but it does not name most of them individually, which is normal for a distributor serving retail, quick-lube, and installer channels. Two relationships are on the public record.

The Rain-X relationship is a licensing and manufacturing partnership rather than a downstream sale, but it documents a named brand owner that relies on Highline Warren's fluid production.

Sourcing evidence

Highline Warren's US import record reads the way a distributor's should. Public bill-of-lading records show 1,299 sea shipments from October 2018 through August 2026, averaging about 9.5 TEU per month, with the most recent shipment logged on August 19, 2026. The declared goods are finished and branded aftermarket consumables, not raw components: oil and air filters, motor oil and additives, tire-repair tools and inflators, and lubrication hand tools. That inbound mix is consistent with a company that buys finished product to distribute and blends its own fluids domestically, rather than importing parts to manufacture.

Seven shown of the top import relationships. Origin countries are led by China, Germany, South Korea, Taiwan, and Vietnam. ImportYeti estimates cumulative ocean-shipping spend at roughly 7 million dollars across the record, with cost data covering about 81 percent of shipments, an order-of-magnitude figure rather than an audited one.

Coverage caveats: these are US ocean-freight records only. Air, truck, and rail movements do not appear; some records name freight intermediaries rather than manufacturers; and product categories come from declared manifest codes, which are noisy. Absence of a record is not evidence of absence.
