I just removed all the wax oil from my defender 90 and find some orange original de carbon V45 2056 23 shock abs.

Did a google search and see they may be from a discovery.

Does anyone know the height difference from a standard defender shock with these or how long these guys are?

I need to buy some new shocks but want to keep it same height as is now.

Thanks

I think you first need to establish is the car at standard ride height?
If its std I would just go for std cheapo shocks at 15 quid a corner.
Posh ones are nice but to many people get sucked into the must have heavy duty this and that when the std gear is more than adequate.

The shocks shouldn't make any significant difference to ride height of a 2 ton + car. The gas pressure inside exerts some force compared to non gas shocks, but not that great.

I still find it strange that people tend to think that their shock absorbers or dampers have any influence on the vehicle's ride height.
There are essentially two components which make up the suspension system, springs and shock absorbers.
The springs will set amongst other parameters the ride height, the two factors here will be the overall length and the compressability; longer springs will generally mean a higher ride and compressability will contribute to the softness or hardness of the ride as well as the ride height when supporting the weight of the corner of the vehicle.
The shock absorber's main job is to reduce or damp the bounce of the springs. Left without dampers or if the dampers are faulty, the vehicle will bounce almost uncontrollably leading to horrendous overall handling.
The only time the ride height should be considered when selecting a shock absorber is when a lift has been applied, in which case the damper should be chosen so that under normal loads the travel should be generally equal, up and down or fully open to fully closed.
Other than that, the type of shock absorber one fits, gas filled, adjustable or good old fashioned oil filled 15 quid jobbies is entirely up to you and you bank manager. Just remember, it's good practice to do whatever you do to the suspension, do it on both sides at the same time.

Thanks for info I think I need to get out a spring and measure it!
