Terms of Use and Sale

Our products are intended for off-road use only. The purchaser assumes full responsibility for compliance with all applicable regulations respecting vehicle modifications. Any modifications from the original design of a vehicle are done at the user’s own risk.  Purchase or installation of any of these products constitutes acceptance of these terms by the purchaser.

**Note that the X-Link previously came in 2 versions optimized for either gold or silver blade GM/ACDelco throttle bodies as pictured down the page.

The current convertible version can be used with all GM throttle body types shown below, as well as the Nick Williams 103mm.

** The X-Link is not designed for aftermarket throttle bodies with magnetic sensors or with sensors not calibrated to GM specifications. In those cases our programmable D2A module may allow you to use those throttle bodies on these vehicles. An x-Link is not needed.

GM LS2/L76 90mm- 12570790


Non GM clones and 102's with magnetic sensors are not directly compatible with the 2003-2007 truck and Holden LS1 TAC modules. A programmable D2A module is required instead of an X-Link.



Want to install a LS2, LS3, LS7, L76, L99 90mm or a L92, Trailblazer SS, GMT900 87mm 6 pin throttle body on a GM or GM Holden electronic throttle control(ETC) vehicle originally equipped with a 78mm 8 pin throttle body?

And see full throttle range?

TRP's X-link interface modules make it possible!  

  • Applications: 2003 - 2006 and 2007 Classic Full -Size GM trucks, 2004 SSR, 2004-2005 Holden VZ LS1 vehicles
