Question 1

How do Johnson Rods Work?

Accepted Answer

Johnson Rods work in conjunction with your factory airbag springs to control the height of your vehicle by adjusting the height sensor level with a different length rod.  The result is that your vehicle will ride higher (lower with a lowering kit) in each mode of oration as compared to the stock mode heights.

Question 2

Will I still be able to control the height of my vehicle using the Terrain Response System?

Accepted Answer

Yes, the functionality is maintained and the vehicle height modes can be controlled using the Terrain Response System from inside your vehicle.  In some cases with larger tires or with lowering kits, the access mode may not be available.

Question 3

Will the speed limitation for off road mode still be activated?

Accepted Answer

Yes, when off road mode is selected after the lift kit is installed the car will raise up further and the the speed limiter will lower it back to the new normal height when it is exceeded.  For everyday driving your vehicle will be higher with the lift (lower with a lowering kit) than the stock height.

Question 4

Do I need to keep the lift rods on full time?

Accepted Answer

No, you do not have to keep them on full time and it is possible to use them when just going off road.  That said, most customers do leave them on full time and get an alignment.

Question 5

Is installation difficult?

Accepted Answer

Installation of Johnson Rods is very easy.  Many Land Rover dealers or independent shops can install them for one hour of labor plus an alignment.  Many owner install them themselves.  No special tools are needed.

Question 6

Will a rod lift work if I have coils rather than airbags?

Accepted Answer

No, Johnson Rods require a functioning air suspension system to work.

Question 7

Will the rods affect my warranty?

Accepted Answer

Technically any modification to a vehicle has the potential of voiding a warranty repair.  Review your warranty and understand that risk before doing mods.  Many dealerships do this install and stand behind their work.  Check with your dealership on warranty issues and ask them to do the install.
