Anybody tried this? (USA sites say it is easy and improves the ride?)


My springs and bushes etc. are 40 years / 98,000 miles old......


I could get some new Crown ones from Lighthouse for £150 each or I could get a lift kit, but I don't really need a lift...


Anybody got some so I could give it a try?

Tried a lift on the YJ ....now,the 1 Tonne....
Rubicon Express.  2 1/2 " lift .....it was good and great articulation
Then went 4 1/2 for larger tyres.....also great....l
Sold them both when doing SOA with 1 tonne axles on the YJ
Used Crown from Lighties HD rears on all 4 corners
Works well and supports the weight of 1 ton axles and 40" tyres no prob

Sorry don't have any to loan.

Just to be clear, if anybody has (or knows of...) some standard YJ parabolics lying around I will pay money for them.....


(unless somebody tells me its not worth doing?)

I have now been told that standard TJ ride height is lower than CJ, so putting stock YJ rears on will not really work...


Can anybody confirm this?

[BIGDRY]

who told you that Jonny? i too am looking into this plan for my cj7 which also "sports" old tired oe springs - i too do not want a massive lift (it wont fit in my garage if i go much higher than stock!)

it does make sense as the only yj spring conversions for cj i have seen seem to feature yj +2/2.5" springs - i guess if the stock yj spring is indeed softer it would let your cj7 sit lower hence the extra ride height version being best suited for cj7s.

If I remember correctly....
YJ rear shackles have the top bolt through the çhassis ....half way up...
CJ rear shackles are held by a bracket riveted to the bottom of the çhassis


Therefore....


YJ springs on a CJ will have maybe an inch more lift at the rear than when on a YJ...
