Part# KB-TRAM-LINK-SET-NS-2BRL Kustom Bitz manufactured here in Australia is this tunnel ram accelerator linkage kit specifically made to suit the AussieSpeed tunnel ram intake but will suit other tunnel rams.  The Aussie Speed tunnel ram intake manifold tops correctly mount the caburetors so they are level, all other brand tops are dead flat which when installed on the engine fitted in the car means the carbys end up on the same angle as the engine [not level] which can effect fuel bowl filling, performance etc.. This may or not matter to you, however the cheap chineese universal linkage kits made to suit the flat top styles, and hence are not so easy to fit to the AussieSpeed tunnel rams.

Other features.
For automatic cars you can mount our kick down cable bracket to the accelerator cable mount as an extra when required.

This part number is for mounting the carburetors in the North - South position [fuel bowls inline up and down the car].  The accelerator cable bracket can be mounted at the back carb or the front carb depending on which works out best for clearances etc.

Kustom Bitz can fit and install at our workshop in Croydon VIC or we can custom tailor a link set up to suit your application. All fitting and custom work is done at an hourly rate.
