Hello

I'm thinking about renewing my Defender suspension this year. The current one is quite tired and sagging an inch to the right side.

First of all let me describe my car and it's use. It is a 1995 90 300tdi, with no anti-roll bars, and with 110 front springs fitted by the previous owner. I have a bullbar, a steel steering guard, a spare wheel carrier and plan to add a Browncurch roof rack. The objective of the roof rack is to be able to carry 4 people with their climbing/mountaineering equipment on the roof, or a rooftent in the future

The car is a daily driver, with weekend offroad use. I don't tow, but ocasionally carry some stuff in the back when doing some long trips. I also carry 4 people on the rear bench seats sometimes.


The original plan was to get some OEM Boge shocks paired with genuine LR springs and spring isolators.

It was recently sugested for me to get RRC "Police Spec" springs (NRC4304?) paired with spring isolators. I was told that they give a very small lift (1") and provide very good articulation.

- Are these police spec springs any good?

- Will they handle loads as well as the stock setup?

- Is the lift really that small? I'm not after a lifted suspension, can't see the point of them in a Defender.

- Can they be installed with the standard lenght OEM Boge shocks?

I know the genuine std or HD springs are a safe bet, but the really low price of the Police Spec springs is really, really tempting.

Thanks in advance for all the help
 
I had a set on the back of a disco1 which was great the disco sat 2" higher than with std springs fitted, when I went to buy dry dog food from the farm I would buy 20 x 15kg bags of it at a time and when the disco was loaded up in the back with the dog food the car sat level, hope this helps ;)
 
standard discovery rear springs on a 90 are very firm to say the least, so going more HD than that would just about shake your teeth out , JMHO , you could try running with a discovery set as will be available for next to nothing , and work it out from that . another option is stay with standard and fit airbags in rear springs , that way you can vary suspension to suit load .

Are you sure it's safe to carry four people and all their climbing/mountaineering equipment on the roof ???

Obviously, the 4 people (me included) are going inside the car.
Not much space left for the climbing equipment, so the rack comes useful
 
I have just replaced my springs with Range Rover Police Spec 4304's which are rated at 170lb/in. I replaced the front springs with NRC 2119 springs that are rated at 150LB lb/in.

My vehicle is a 1996 Truck Cab. I have an electric winch on the front with a heavy duty winch bumper too support it. The vehicle drives perfect with two passengers and equipment in the back over rough terrain and Off Road. I haven't hit the bump stops yet! and I have been on some rough tracks in the North York Moors.

I also replaced all the shock absorbers with standard shockers all round. I'm really happy with the conversion as the ride previous was way too hard. My truck now drives like a go-cart on the road yet absorbes kerbs and pot holes like there not there. Overall I'm very happy. and the spring can be sourced for £9 per spring. I got all mine from Paddocks.

Hope this helps.:nopics::)

Still regarding the Police Spec NRC4304, does anybody knows why the high load rate of 1106lbs, as well as it's effect?
Thanks
 
I recently had the opportunity to drive a Defender with the NRC4304 Police Spec springs and really liked it.

Can those springs be mounted with the original lengh shocks?
Thanks
