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 there are different versions of the X-Link.  The Current production version is designed for gold blade Genuine GM throttle bodies as GM has discontinued the silver blade LS2 throttle body.

The  previous version (C1 convertible with removable jumpers) can be used with all GM/ACDelco 87 and 90mm gold or silver blade throttle bodies, as well as Nick Williams 103mm throttle bodies.

"Older Gold" version X-Links are designed for use with GM/ACDelco 87mm and LS3 90mm 19420707 throttle bodies both of which have gold/brass colored blades. They can also be used with Nick Williams 103mm throttle bodies.

"Older Silver version X-Links are designed to be used only with GM/ACDelco 90mm 19420034 silver blade throttle bodies.

** 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.

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. In some cases the electric motor used in these is not compatible with the 03-07 throttle control system.
