Just because your 4 wheel drive indication is “ON”, does not mean that it is working or working well.  Currently the Polaris 4 wheel drive setup  is controlled only by an ECU voltage to an electromagnet internal to your front differential.  The voltage and current provided to your front differential from your ECU is in most cases extremely weak to nearly non-existing.  Poor voltage or current flow to your front differential can be detrimental to your front differential internal components by causing them to constantly lock and unlock under heavier loads due to the inability of the electromagnet to hold.  This constant banging back and forth can have devastating effects on all your front differential internals while causing premature wear and sometimes catastrophic failure.  You can prevent this before it is a problem by simply installing the Tru-Lok 4 Wheel Drive Harness.

This Tru-Lok harness is a plug and play setup! The Tru-Lok WILL NOT throw a code on your dash.  Easy to install, this harness will ensure you are getting full power to your front differential at all times and not the weak and inconsistent power the ECU sends it.  This is a must have upgrade for your unit.  Not only can you prevent some costly internal failures by providing a stronger more consistent electrical signal, but you will also have a much stronger and better feeling 4 wheel drive setup you can count on.  Do not be fooled by imitations, the Tru-Lok harness is the original harness of its kind, designed on the race course for racers. Built with marine grade components, it has been battle tested for years in the nastiest hill climbs, the fastest races, and the deepest and wettest mud holes.  When you want the best, demand the original Tru-Lok Harness.
