Can I pick up my order or have it installed at your shop?

Absolutely. We offer local pickup on most products and full professional installation at our shop in Washington, MO. Whether you just want to grab your parts or have our techs handle the install, we’ve got you covered. Give us a quick call at 636-429-7020 or message us to schedule a visit — we’ll make sure the parts are ready when you arrive.

How do I know if this part fits my vehicle?

Unsure if it’ll fit? No problem — that’s what we’re here for. Send us your vehicle’s year, make, and model, and we’ll verify fitment before you order. We can also point you toward compatible upgrades or supporting parts if needed.

What if I need to return a product or it’s defective?

Most unused items can be returned within 30 days in their original packaging. Some products are covered by a manufacturer’s warranty as well. If something arrives damaged or doesn’t meet your expectations, just let us know — we’ll help you get it replaced, refunded, or repaired. (Tracking updates are also emailed automatically once your order ships.)

What's the lead time on custom or fabricated parts?

Many of our parts are built to order — especially fabricated or performance components. These can take additional time to produce before shipping. Lead times vary by manufacturer and demand, but we’ll always keep you updated along the way. If you’re working on a tight schedule, reach out before ordering at 636-429-7020 and we’ll confirm current availability or estimated ship dates.

For the daily driver that sees the occasional weekend event, the Hamilton Cams 188/220 Cast Camshaft fits 1989–2018 5.9L/6.7L Cummins engines with a 1,700–4,500 RPM operating range, EGT drops of 200-300 and 40-60hp gains seen depending on fueling and turbo.

Why Choose the Hamilton Cams 188/220 Cast Camshaft?

  • Daily-driver friendly – Intended for daily-driver and light-competition Cummins builds.
  • Cast construction – No cam tunnel bushings called for, unlike the steel version.
  • Cooler EGT – Drops EGT 200-300.
  • Proven gains – 40-60hp seen, depending on fueling and turbo.
  • Broad coverage – One grind across 12-valve, 24-valve, 5.9L common-rail and 6.7L Cummins application groups.
Fitment Notes
  • 12v “drop in”: no more than .018″ piston protrusion and at least .055″ valve face depth with a standard head gasket and a 99 intake centerline.
  • 24v “drop in”: no more than .018″ piston protrusion and at least .038″ valve face depth with a standard gasket.
  • Short on piston-to-valve clearance? Run an oversize head gasket or cut valve reliefs.
  • Although considered a drop-in cam, it is important to check clearances.
  • Hamilton always recommends new lifters when changing a cam.
Installation Highlights

Apply a liberal amount of quality assembly lube to the cam and do not let the engine start without oil pressure. On a new engine, lube the oil pump and prime the filter. Disconnect fuel and spin the engine on the starter until oil pressure reads or oil reaches the rocker arms, then start it and bring it up to operating temp. Re-torque or hot-torque the head before adjusting valves — set lash last — and change the oil after break-in.
