Item was half ass machined....
Item was half ass machined and had to have been done on Friday 10 minutes before weekend. The rocker arm hold down heli coils were put in upside down and the mounts for the fuel rail were machined to small. The packaging was destroyed by time it arrived
Response from Advanced Truck PartsFeb 23, 2026
We’re very sorry to hear about this experience and appreciate you bringing these details to our attention. The machining issues you described — heli-coils installed incorrectly and fuel rail mounting surfaces out of spec — are serious concerns. Components like rocker assemblies and related engine parts must meet precise tolerances, especially for diesel and heavy-duty truck applications. What you’re describing is not acceptable. We’re also sorry the packaging arrived in poor condition. While carriers can sometimes cause transit damage, packaging should be sufficient to protect precision semi-truck and engine components during shipment. We would like the opportunity to review this immediately. Please contact us directly with your order number and, if possible, photos of the machining issues and packaging condition. This will allow us to escalate the matter to our quality control team and supplier for investigation. We take product quality seriously at Advanced Truck Parts, and we appreciate the chance to address this properly.
