⚠️ HX35 Application — Verify Transmission and Turbo: This turbocharger uses the HX35 configuration. Confirm the original turbocharger and its connections, particularly on automatic-transmission trucks. For an OEM-style HY35W stock replacement in the listed 2000–2002 automatic application, see SL-100-075. If selecting an HX35 upgrade for a truck originally equipped with an HY35W, verify the installation requirements for that conversion.
