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.

Description
This single fixed vane turbocharger install kit from WCFab for 2001-2004 Chevy Silverado 2500 / 3500 HD trucks contains what you need to swap from your stock IHI style turbo to a larger frame Borg Warner S300 style setup on a 6.6L LB7 Duramax diesel engine. Upgrades your existing air cleaner setup to a 4" fabricated aluminum intake with heavy duty sheet metal air box and high performance dry filter with pre-filter cover. Intercooler hot and cold side charge pipe plumbing are also updated to high flow 3" diameter mandrel bent 14 gauge aluminum tubes. Includes our upgraded high flow 3" fabricated billet y-bridge kit which replaces the restrictive stock upper intake manifold to finish off the air flow path into the engine and allow for maximum horsepower and efficiency gains. Supplied Oil Lines are high-quality stainless steel braided Parker Lines with the oil feed line routing from the main oil galley on the side of the engine block. A variety of popular turbo size options (sold separately) mount to a T4 fabricated steel pedestal with spacer which is compatible with our 2" high flow stainless steel up pipes. Included high temp ceramic coated turbo downpipe connects to your existing exhaust front pipe V-Band clamp. This simplifies installation and requires NO cutting or modification to your exhaust system. If you are not purchasing a genuine Borg Warner turbo from us, you must specify the brand and details of what you are using so that our sales team can assist you with placing your order and ensure proper fitment. You may be required to ship a separately supplied turbo to us in advance for mock-up to build your kit. Your order lead time starts when we have the turbo needed to build your kit our possession. Includes Driver Side Transmission Dipstick Tube, making installing the down pipe easier.
