Why iDrive?


Rather than a traditional accelerator cable, many modern vehicles use 'fly by wire' throttle technology. This system relies on a sensor that measures the pedal pressure and position and sends a signal to the vehicle's engine computer which converts to acceleration. Many of these fly by wire systems have a noticeable delay. iDRIVE allows you to tune the signal from the accelerator pedal with multiple inbuilt settings to ensure you find a setting that suits your driving style, although there are other products on the market that can offer this performance.

Do airbags affect articulation/flex/travel of my vehicle when four wheel driving?

If you were to have no airbags fitted to your vehicle and you were towing or carrying load or even just 4wd’ing with passengers and your vehicle was sitting low, sagged and uneven, then you are losing suspension travel due to the weight on the vehicle shortening the gap between your chassis and axle, therefor leaving you to potentially bottom out. If you add our airbags & inflate them to return your vehicle back to its level ride height position you are eliminating that factor and gaining back the travel/flex that you lost when under load.

So answer to your question is, no our airbags do not affect your articulation providing you use them correctly as stated in your Airbag Man owner’s manual.

The only way you will lose suspension travel is if you add too much pressure into the airbags forcing the suspension to extend out past standard height when not required. This will limit your downward travel/flex of your suspension.

Airbag Man Design and Manufacture vehicle specific airbag kits to work with the full suspension travel or your vehicle, make sure you operate the airbags correctly as stated in your Airbag Man owner’s manual to ensure suspension articulation is maintained

How do TREDS work?

The ability of TRED's to get you out of a sticky situation comes down to the provision of superior traction when the ground under your tyres is simply too unstable to traverse. There’s more than enough traction on top to get your vehicle up and going and enough traction underneath so that TRED’s don’t just pass straight under your tyre

Will Pinnacle 4x4 supply and fit any brand of products?

Yes we can supply and fit any brands of products.
