About Hardline Products

Hardline Products has been a cornerstone of the power-sports accessories market since its founding in 1992. Based in Simi Valley, California, the company was started by Kevin Schulte — a lifelong rider whose firsthand frustration with the lack of quality aftermarket parts drove him to build something better. What began as a one-person mission to fill a gap in the market has grown into a nationally recognized, family-owned brand trusted by enthusiasts and OEMs alike.

Today, Hardline Products serves a remarkably wide swath of the sporting world: on- and off-road motorcycles, boating, personal watercraft, marine applications, all terrain vehicles (ATVs), snowmobiles, and karting. That breadth of focus is not accidental — it reflects the brand's core philosophy that serious riders, boaters, and racers all deserve purpose-built accessories, not generic hardware-store solutions.

Trusted by the Industry's Biggest Names

One of the clearest measures of a brand's credibility is who trusts it with their own label. Hardline Products has earned that trust from some of the most respected names in power sports, producing private-label products for manufacturers and distributors including Yamaha, Polaris, Moose, Quadboss, West Marine, Mercury Marine, and others. That OEM relationship means Hardline's quality standards are held to a higher bar than most aftermarket suppliers.

The company's approach combines modern manufacturing technology with what they describe as "old-school" craftsmanship fundamentals — a balance that keeps products both innovative and reliable. Dealer feedback, customer input, and OEM partner guidance all feed directly into ongoing product development, ensuring the catalog stays relevant to real-world use.

What Hardline Products Makes

The product line touches nearly every aspect of powersports ownership and operation. Their registration letters and numbers for boats and PWC are among their most recognized offerings — USCG-compliant marine vinyl decal kits engineered to resist UV fading, fuel spills, and high-speed water exposure. For riders in the dirt and on the track, exterior racing decals under the Dirt Digit line deliver the bold, durable graphics that competitive motocross and enduro racers demand.

On the instrumentation side, Hardline's gauges — particularly their inductive hour meters and digital tachometers — have become a go-to tool for powersports maintenance. Used across motocross bikes, ATVs, UTVs, snowmobiles, and outboard marine engines, these solid-state digital meters allow owners to track engine runtime precisely, ensuring oil changes, valve adjustments, and rebuilds happen on schedule rather than by guesswork.

Built by Enthusiasts, for Enthusiasts

What sets Hardline Products apart from larger corporate aftermarket suppliers is the culture behind the catalog. The team is made up of active parents and lifelong powersports participants — people who ride, boat, and race on the same equipment they help equip. That insider perspective shapes everything from product design to packaging, resulting in accessories that feel less like afterthoughts and more like essential gear. Whether you're prepping a jet ski for a summer season, maintaining a four-stroke race bike, or registering a new boat, Hardline Products has been solving those problems for over three decades.
