Designed for high-performance and commercial-level setups - this kit refines your Karcher HD pressure washer into a smoother, more powerful detailing tool.

If you’re using a Karcher HD or similar commercial-grade pressure washer, you already have solid hardware. But the accessories often don’t match that same quality. Long, clunky lances, stiff hoses, and restrictive fittings all compromise flow and handling. That’s where this upgrade kit steps in.

We’ve built this setup specifically for the demands of higher pressure and heat-capable units. It pairs flawlessly with most Karcher HD systems, Honda-based units, and other pro machines that use a 3/8" outlet.

At the heart of it is the MTM SG35 short pressure washer gun, built in Italy with stainless steel internals, a 360° swivel, and fast quick-connect swaps. Unlike the long factory wands, this setup gives you direct, agile control - ideal for precise detailing, underbody rinses, or tighter working areas.

The Propulse UBERFLEX 15.2m hose isn’t just longer - it flows better, resists kinks, and stays flexible under load. It’s a major upgrade from the stock heavy rubber hoses that want to fight you the whole job.

Also included: the Aquatouch 030 nozzle set, giving you a full range of 0° to 40° tips - plus a wide fan swivel nozzle for those awkward angles around guards, sills or engine bays.

Need foam? This kit supports all popular foam cannons, and is fully compatible with high-flow units and heat-rated pressure washers.

Whether you're upgrading your shop rig or setting up a mobile van, this pressure washer upgrade kit eliminates bottlenecks and delivers the kind of control and performance you expect from pro-grade equipment.
