Before you call
Fast answers to common questions
How fast do you reply?
Phone calls are usually answered in under 30 seconds during business hours. Email and form messages get a same-day reply Mon–Fri.
Do you charge for tech support?
No. Pre-sale advice and after-sale setup help are free. We invest the time so you buy the right tool the first time.
Can you help me decide between OEM and aftermarket?
Yes — that's the most common call we get. Tell us your engine mix, model years, and what you wrench on, and we'll lay out the trade-offs honestly.
Do you carry [a specific tool]?
If it's a professional HD diagnostic tool, almost certainly. We sell INSITE, DiagnosticLink, DAVIE, PTT, ServiceMaxx, Cat ET, Jaltest, JPRO, TEXA, Autel CV, FCAR, and the Nexiq family. Ask and we'll confirm pricing, compatibility, and lead time.
Can I order online?
Yes — most products are listed in the storefront. For configured kits, financing, or fleet pricing, calling is faster.
What if I'm stuck on a regen right now?
Call. We'll try to talk you through what's blocking it before we sell you anything. Sometimes the answer is "your delta-P hose is plugged."
