Product Description
The BD DIESEL 1047116 Turbo Turnbuckle is the easiest way to fine-tune wastegate adjustment on 2001–2004 GM Duramax LB7 applications running an aftermarket turbo or external wastegate. Designed for fast and accurate boost control tuning, this stainless steel turnbuckle lets you increase or decrease wastegate rod throw in seconds — without fighting tight spaces or removing the wastegate assembly.
Built from corrosion-resistant stainless steel with a swivel-style design, the BD Diesel turnbuckle helps prevent rubbing, interference, and awkward angles during adjustment. Simply place a wrench on the shaft and turn to increase or decrease rod length for precise mechanical boost control. This is the perfect solution for earlier BD kits or aftermarket turbo setups that need easier wastegate tuning.
