The vacuum pump quit pulling its weight years ago. šŸ’€

The DieselSite 6.5L Vacuum Pump Elimination Belt is for the guys cleaning up the weak links on their GM 6.5 build and making the engine bay simpler, tougher, and less likely to leave them stranded. One shorter belt, less clutter, less nonsense. šŸ”§

If you’re already running a Turbo-Master setup, this is the next move. Delete the dead weight and let the old Detroit diesel breathe a little easier. Because nothing ruins a good tow rig faster than a seized vacuum pump smoking the belt on the side of the highway. 😈

Simple upgrade. One less failure point. More peace of mind when the truck’s working hard.

Factory boost control is soft.
The DieselSite Turbo-Master Adjustable Wastegate Controller 98.5 isn’t. šŸ”„

This is the kind of upgrade that wakes a 24V Cummins up and reminds you these trucks were built to work angry. Faster spool-up. Harder pull. Less wastegate nonsense bleeding off boost when you’re trying to lean into the throttle.

No flashy gimmicks. No fake horsepower promises. Just tighter boost control and the kind of response that makes the truck feel sharper, meaner, and way more alive every time the turbo lights. 😈

Because a Cummins shouldn’t feel lazy. It should feel like it’s trying to rip the pavement out from under it. šŸ’Ø

The DieselSite Steel Impeller Water Pump for late 2004.5–2007 Ford 6.0 Powerstroke is built around one simple idea: stop trusting plastic in a motor that already runs hot enough to make grown men nervous. This is the upgrade you do when you’re tired of wondering if your cooling system is going to tap out on a long pull, a loaded trailer, or a summer day in traffic. 😈

Where OEM plays it safe (and eventually gives up), this pump leans into durability—steel impeller, heavy-duty construction, and a design meant to keep coolant moving when the engine is working for its life. It’s the kind of part that doesn’t ask for attention… it just quietly keeps your truck alive.

No drama. No gimmicks. Just a cooling system piece that finally feels like it belongs behind a tuned or hard-working 6.0. šŸ’€

And yeah—this is one of those upgrades where you install it once, torque it down, and stop thinking about it every time your temp gauge creeps up a hill.

Clean, simple, and built to outlast the problems people know too well on these trucks.

There’s a different kind of silence on Memorial Day.

Not the shop kind… the kind that makes you stop and think about everything that came before the work, the builds, the long nights in the garage.

The people we honor today gave everything so the rest of us could keep building, driving, working, and living free.

At DieselSite, we don’t take that lightly.

We remember. We respect. We carry it forward.

A tired turbo doesn’t always scream for help.

Sometimes it just feels… off.

Slower spool. Higher EGTs. Less punch than it used to have.

The DieselSite 1999.5–2003 7.3L Turbo Rebuild Kit brings the GTP38 back into its proper window — restoring bearing support, sealing surfaces, and internal efficiency so the turbo can do what it was built to do in the first place.

Before you replace it… rebuild it.

Because most of these turbos aren’t dead. They’re just worn out.

Some upgrades you only notice when you don’t have problems anymore.

The DieselSite 1994–1997 OBS 7.3L Upper Radiator Hose with Billet Housing replaces the factory thermostat housing setup with a stronger, cleaner solution — paired with a custom-molded, high-temp hose built specifically for the job.

Designed to improve sealing, durability, and serviceability, this setup brings modern reliability to one of the most overlooked weak points in the OBS cooling system.
Built to fit right. Built to stay right.

Every Cummins has that moment.

You roll into the throttle and wait… half a beat too long for the turbo to wake up.

The DieselSite Wicked Wheel 2Ā® for 2005–2013 Cummins is designed to erase that delay. A billet compressor wheel engineered for quicker spool, smoother airflow, and a more responsive turbo curve under real driving conditions.

No flash. No noise. Just a truck that feels more alive from idle to highway pull.

Sometimes the smallest part changes the way the whole truck drives.

6.0L POWERSTROKE — STOP CHASING OIL LEAK GHOSTS

Hard starts. Low rail pressure. Random cutouts that leave you scratching your head. On the 2004.5–2010 6.0L, it’s almost always the same suspects hiding deep in the high-pressure oil system.

The DieselSite Standpipe & Dummy Plug Kit is built to fix one of the most common failure points in the system — upgraded sealing design, improved o-ring materials, and a tighter, more reliable fit that helps keep oil where it belongs: under pressure, not leaking off into a no-start headache.

It’s one of those upgrades that doesn’t scream for attention… until you realize the truck just starts every time again.

DieselSite — fix the leak, fix the problem.

WHEN THE 6.5L STARTS RUNNING HOT, THIS IS THE FIX

The DieselSite 6.5 SuperCool Kit isn’t a ā€œsmall upgradeā€ — it’s a full cooling system rethink built for one of the most heat-prone diesel platforms out there.

This kit brings everything together: upgraded water pump, heavy-duty fan clutch, high-flow 9-blade fan, proper thermostat setup, radiator cap, and gaskets. The goal is simple — keep coolant moving and temps under control when the truck is actually working for a living.

Because the truth is, the factory setup was barely enough for normal driving. Add towing, load, or heat… and things climb fast. This kit is built to stop that climb before it starts.

Not flashy. Just effective where it counts.

DieselSite — turn down the heat and get back to work.

COOLING YOU CAN COUNT ON. NO GUESSWORK.

When temps climb and hard miles stack up, the weak link shows itself fast. That’s why DieselSite built their replacement water pump for the 2011–2015 Ford 6.7L Powerstroke to go in clean, fit right, and keep the cooling system doing its job without drama.

This is a direct-fit, stock-style replacement designed to restore proper flow and reliability where worn factory pumps start to fall off. Built for real-world diesel punishment, whether you’re towing, hauling, or just stacking miles.

Simple upgrade. Big difference where it matters most — under the hood.

DieselSite. Built for the long haul.
