US Perfect Auto Parts & Supplies Inc.Frequently Asked Questions
Brand new, 100% new components throughout — no rebuilt cores, no reused housings, no core charge. Every unit is dynamically balanced and tested before it ships. See our quality control process for details.
The most reliable way is the part number on your old turbo's nameplate — match it against the OEM and interchange numbers listed on our product pages. If the plate is unreadable, send us your VIN or engine serial number and our team will identify the correct unit for you.
Every product page lists the engine, model years, and full cross-reference numbers. If your old turbo's part number appears in the list, it fits. Many engines used different turbos across model years and emissions tiers, so always verify by part number rather than engine name alone — and when in doubt, ask us before ordering.
It depends on the listing. VGT turbos are offered without actuator (reuse yours if it tests good) and, for many models, as complete assemblies with a pre-installed actuator. Each product page states clearly which version it is. Fixed-geometry turbos with internal wastegates ship complete.
Heavy-duty and medium-duty diesel: Cummins, Detroit Diesel, Caterpillar, PACCAR, Volvo, Mack, International/MaxxForce, Hino, Isuzu. Pickup and light-duty: Dodge Cummins, Ford Power Stroke and EcoBoost, GM Duramax. Off-highway: Kubota, Bobcat, John Deere, Case/IH, New Holland, plus Polaris powersports and universal performance turbos.
Our turbos are built to match the original equipment's dimensions, fit, and performance — OEM-spec construction with new components, balanced and flow-tested at the production stage, and produced under EPA, CARB, DOT, ISO, E-Mark, and SGS recognized standards.
From our US warehouse. In-stock units dispatch within 24 hours of payment on business days — your parts are already in the country, not waiting on a container.
Most US orders arrive within 2-5 business days by ground service. Expedited shipping is available if your truck is down and you need the turbo sooner — contact us for options.
Yes. Single units ship by parcel carrier; pallet quantities ship by LTL freight. We pack every turbo in protective foam to prevent transit damage, and bulk shipments are palletized and strapped for freight.
Our primary market is North America. For international wholesale inquiries, contact us with your destination and quantities and we will quote shipping.
Send us your old turbo's part number, your VIN, or your engine serial number before you order. We verify every part number against the application before it leaves the warehouse — it is faster to confirm fitment up front than to process an exchange later.
Yes — that is our core business. We supply diesel repair shops, fleet operators, parts distributors, equipment dealers, and rebuilders across North America. See our wholesale program for details.
No minimum. Order one turbo to test our quality, or a full pallet. The same product and the same one-year warranty apply either way.
Yes. Volume pricing kicks in on multi-unit orders and scales with quantity. Tell us the part numbers and quantities you move, and we will quote a program price.
Yes. We offer white-label support for distributors and brands — neutral packaging and labeling options so you can supply turbos under your own name. Contact us to discuss requirements and volumes.
Yes. We are built for repeat supply, not one-off sales. Fleets and shops that standardize on us get consistent product, stable pricing, and stock visibility on the part numbers they replace most often.
One year, unlimited mileage, on every turbocharger we supply — from the date of purchase, whether you bought one unit or a pallet.
Manufacturing faults, material defects, and workmanship issues. If a unit fails from a genuine product fault within the term, we stand behind it. The warranty applies when the turbo is installed correctly and the engine is running properly — failures caused by oil starvation, contaminated oil, or debris entering the intake are installation-environment issues, not product defects, which is why we recommend fixing the root cause of the old turbo's failure before installing the new one.
No. Our turbos are brand new, so there is no core to return and no deposit tied up — unlike remanufactured units that typically carry a refundable core charge of several hundred dollars.
Send us your order details and photos of the issue. Our US-based team reviews claims quickly and works with you directly — you are not chasing an overseas supplier when you need help.
Yes. Unopened units can be returned or exchanged within 30 days of delivery. Contact us with your order number and we will arrange the swap or refund.
Yes, and this step saves a lot of money. A turbo rarely fails on its own. Oil starvation, a clogged feed line, or something sucked into the intake will take out the new turbo too if you ignore it. Before you install the replacement, check the oil supply, the drain line, and the intake for damage or debris. Fix what caused the first failure, then fit the new one.
Fill the oil inlet with clean engine oil while spinning the shaft by hand, so the bearings are wet before first fire. After installation, crank or idle the engine for 3-5 minutes without load to establish full oil flow. Never rev a dry turbo — the first 30 seconds decide its service life.
It depends on the platform. Some VGT actuators (PACCAR, Volvo/Mack, Detroit) require dealer-level software to pair with a new turbo body — our complete assemblies with pre-installed actuators avoid this step. Other platforms only need a verification sweep through the ECM after installation. Each product page notes what applies.
Yes. Fresh oil and a new filter are cheap insurance — the old oil may carry the metal debris that killed the previous turbo. Also flush or replace the oil feed line; a partially coked line is the most common cause of repeat failures.
Fitment help, part matching, installation questions, and warranty handling — by phone and email, from a US-based team that speaks turbo, not scripts. If you run into anything after your order ships, reach out and we will sort it with you.
