Hi can anyone please advise. Fitted m57 engine conversion and warn winch into my 90 defender. Due to increased weight I have fitted rear springs to front end .Should I now use rear shocks to the front as well. Forgot to mention that the landy sits 2 inches higher at front so I purchased some 2 inch higher shocks for the back.
Thanks

Rear shock have differnt fixings to the front so they won’t just swap over.

Mine was a 110 high cap & winch. Ran standard shocks but better springs

You can use standard shocks with a heavy duty springs, you do not need to uprate the shocks as well. I have this on my 110 with a winch, uprated front springs (same as 90 rears for reference), but still run the standard factory shocks.

All you need to do is match the shock to the spring length, if standard height spring standard shock, if lifted spring then a lifted shock.

That does not seem to be right, are the front springs standard height, or are the rear springs just very old, well worn and sagging? Fitting longer shocks will make no difference to the ride height that is determined by the spring not the shock.

As Phil mentions above, the fitment of the rear shocks is different to the front, so not possible.

However, I think you might be getting yourself a little mixed up.

By and large, the spring will set the ride height of a vehicle. The shock is there to control the up and down motion, aka dampen the movement.

There are lots of different spring rates and lengths, fitting rear springs is ok, but there are probably other ways to do it these days. 20-30 years ago there was less choice and less access to such info. So putting a rear spring on the front was an easy option.

Do you want your vehicle sitting 2" higher? If no, then a slightly higher rate standard length front spring may be a better bet.

As for shocks, it depends on what you are doing with the vehicle. Is it on road, off road. Do you haul a lot of stuff or tow? Do you want stock suspension flex or increased suspension flex and what kind of money are you wanting to spend?

Fitted new rear springs but landy is not sitting horizontly (level)

Normally a 110 sits a bit higher on the rear to allow it been level with weight in it.

What engine was fitted before as there is not much difference in weight between a 300tdi & the m57.
