Because I wanted 1/2" less than the 2-2.5" suspension you could buy for my model to keep it 100% legal in my state, I specified coils all around for the earlier KJ which was around 200kg/440lb lighter. The extra weight of the KK should drop the height by around 1/2". One main difference though is that the rear springs are different. Can see how much bigger the top of the KJ yellow coil is.
I hunted around the wrecking yard and found these top strut, or coil, mounts in the dirt. Found three of them spread around the 4wd section but none belonged to the vehicles where they were. This fitted the coil perfectly.
It was easier the turn the coil upside down and fit the larger end of the coil to the axle perch. The centre hole was too small to fit over the bump strike pad though.
Good excuse to use the new lathe and hog out the centre. Can also cut it out with a jigsaw if needed.
Dropped over perfectly. Fully reversible too as will just sit there under spring pressure the same as the isolator was.
The original bottom end of the coil fitted the upper mount perfectly. The flange just needed a slight bend depending on how the coil was positioned at the top.
Coils sits on just as planned
Coils are made by King Springs who make it for OME and many others as well. Rear springs are KJRR-28. 210 lb-in rate similar to OME (2)948, but with a 3/4" lower free height.
I got a full set of Bilstein shock absorbers from Summit Racing in the USA sent over. The rears are BSN-24-139175 4600 series. The lengths as the stock so no need to reduce uptravel to fit them. I had no clearance problems with the 245/70R17 tyres on 17x8" wheels with +35 offset. The near stock offset helps a lot in the front especially to stop any rubbing.
Even colour co-ordinates! I added extra isolators that were originally on the bottom perch to the top of the left side as the fuel tank weight pulls this side down. Came out exactly even.
Always hated the danger with screw type spring compressors so thought I might as well use my shop press instead. So very easy and fast to do this way, and much safer. Shifter to hold the shaft while using a ratchet ring spanner to take off the nut.
Old versus new. Bilstein BSN-24-139168 4600 series mono tubes with KJRF-27 King Springs. 400lb-in rate similar to (2)927 OME with 3/4" lower free height.
Reassembly was done the same way.
Already to go back in.
No clearance problems at all and no need to change upper A arm like higher lifts.
To break in the new springs I was finding plenty of humps to flex the suspension and going over 'traffic calming' mounds etc at a faster than normal rate to bed everything in.
Think it still fills out the guard nicely. The higher you go the smaller the tyres look!
So ending up at 50mm/2" higher all round than I started. Depending on where you read, that is 1.5" over stock or 2" in the suspension alignment specifications. http://www.brakeandfrontend.com/alig...-jeep-liberty/
Centre of wheel to underside of the flare is 500mm/19.7" front and 520mm/20.5" rear.
The ride and handling I am very impressed with and far beyond what I expected, or thought possible. It is a great combination and much cheaper than going the OME route. All up, including freight locally and from the USA, it cost me $960. Cost would be no more if you specified KK King coils either from the same eBay seller at $175 a pair inc.
