Please beware of inferior throttle shaft bushings as many companies make more expensive bushings or make them out brass, copper or even nylon claim to have the ultimate bushing. The kits are price much higher and these materials are no match to our superior  stainless steel with 7% impregnated lead.  These Barker Bushings© are guaranteed for the life of the carburetor and will outlast and outperform any other bushing material period !! One of the most common byproducts of a warped Quadrajet is the loss of vacuum to the power piston.  The power piston vacuum circuit located between the fuel float bowl and the throttle shaft plate.  When the fuel float bowl is warped, the thick gasket looses its sealing properties due the warping effect thus resulting in loss of vacuum to the power piston which results in poor performance and poor gas mileage.  All of these contributing factors add up to what is known as the dreaded Quadrajet bog, rough idle or no idle. My stainless steel Barker Bushings© can be used to rebush almost any carburetor that has a 5/16s throttle shaft.  We can also rebuild any type of carburetor for any application.    For more information call me at 970-779-0233 and get the real scoop of how your Quadrajet can be rebuilt to a greater level of performance then when it was new. We also provide a high performance Quadrajet rebuilding service for those who race or want a modified Quadrajet carburetor. Call for warranty information.

We NEVER SWAP YOUR CARBURETOR BODIES, THROTTLE PLATES or         PARTS UNLESS WE GET YOUR AUTHORIZATION IN WRITING The purpose of installing this bushing kit is to eliminate the vacuum leaks at the throttle shaft thereby increasing engine response. This is one of main contributing factors to a rough idle or no idle. You may have noticed after a careful examination of the looseness of throttle shaft that in most cases will be on the throttle cable side if not both sides of the throttle plate are wallered out.  The cable side of the throttle plate “bushing” receives the most stress thereby causing critical ware in the aluminum throttle plate resulting in vacuum leak. The throttle plate contains no factory “bushings” of any kind as the hardened throttle shaft after only a few years of use simply wares away the softer aluminum material.  However if your Quadrajet carburetor has other problems you may NOT notice the benefit of the Barker Bushings© kit, so additional repairs maybe needed to your Quadrajet such as the fuel float bowl and air horn assemblies because they are more than likely warped to some degree.  Even if you choose to have me rebuild your Quadrajet or any other carburetor, there may be other issues to factor in such as the condition of the application motor, ignition, cooling systems or other as of yet undiscovered problems you may have. If you choose to do your own carburetor overhaul, it is highly recommended that the Rochester Quadrajet you're intending to install the Barker Bushings© kit into be thoroughly cleaned. The best recommendation would be to install this Barker Bushings© kit in conjunction with the use of the Barker Gang Garage Quadrajet Unwarping© service. Or we can we install the Barker Bushings©, unwarp your Quadrajet for you.  Call for pricing.  Some warranties may not apply.
