Mechanically fine tuning of turbocharger boost levels at the turn of a buckle. Adjustable Turbo Waste Gate Turnbuckle takes all the hassle out of adjusting your performance waste gate. With a BD Turnbuckle you can now leave the waste gate attached to the turbo and simply place your wrench on the shaft of the buckle and increase or decrease the amount of throw in seconds. Cut from stainless steel to prevent corrosion and the swivel design avoids oil return drains and rubbing. The Turbo Waste Gate Turnbuckle is now attached to all BD performance turbos and waste gate kits, but, if you have an earlier BD kit or other aftermarket turbos, the Turnbuckle makes waste gate adjustments a dream.
