Is your JK this heavy?

I have talked to the guys at murchison's too and they seem to have quite a few options for higher load springs, I'm not in brisbane though so it's not quite as simple as take it there and try them out so I had custom dobinsons Springs made in rockhampton, fantastic ride now

Called up Stu at Murchison Products and he knew exactly what springs I would need just by telling him what I had on the Jeep. It's sitting and riding perfectly now

Since this thread began, I've been intending to run mine over a weighbridge, just for curiosity sake, but I haven't done it yet.
I have had Synergy 3" springs on mine though for about 4 years.
I have just measured my lift and found it to be still 3.2" above std at the front and 3.6" above at the rear..........but....... when first fitted they were an impressive 3.5" at the front and just short of 4" by a smidge at the rear. So they have sagged a little but have maintained 3"+ so I'm happy.
All the measurements were taken unloaded with a winch, roof rack and front and rear bar work.
Mine is a 3.8 though so is lighter than a CRD at the front.
The Synergy springs are not really suitable for carrying loads due to the coil rating and design, so if you fit them and then load up for a tour of say, the Gunbarrel or CSR, it's not surprising that they sag.
They, and other brands of the same design. Are more for off road performance than load durability.

Mine is an auto.
There are weighbridges all over the Perth area. Depends on the area you live in.
Main Roads have a list of public weighbridges or try a scrap metal or engineering place in your area.
I used to use one in Midland but I think it hss been decommissioned.

You will know when you have a lot of weight on your jk, mine sagged from a 3" rubicon express front and rear to about a 1.5 in the front and 2.5" in the rear after we had already put 2" spring spacers in to help! It didn't flex well in the rear after that addition 😅
