Front 5100s w/ Trim Packer + Dobinson 1.6 inch rear

I had the Bilstein leveling struts installed in October of 2015 and after cracking the rear lower fascia on a rock while off road I decided to install some sort of lift in the rear and try to keep it somewhat level. I went with the Dobinson rear springs (Non-HD) with Bilstein shocks and RRO trim packers up front. Here is the stock vs. Dobinson spring.

Coming from the Nivomats the ride is smoother and a tad softer. The Dobinson springs gave me exactly 1.63 inches of lift in the rear. The RRO trim packer install was easy as I was able to lower the strut enough to add the spacers on top by just unbolting the strut and nut on the UCA, and dropping the strut down. No removal of the strut, sway bar, tie-rod, etc. needed. One thing noted afterwards is that there is plenty of threads left on the struts to add more spacer lift. As the RRO trim packers are 3/16 inch, a 3/8 spacer should work fine and a 7/16 would probably work as well, but might be pushing it. I wish I had known this before as I would like some more lift up front.

Final result sitting on 275 65 18s. Its not as high as I would like in the front, but it also has the Chief sump plate and MOPAR rock rails which I think is weighing the front down. At some point in the future, I'll probably look for a 3+ inch front lift as I plan on adding a pre-runner and would like to run 33s eventually.

Looks like a nice setup! You could always double down on the trim packers up front for now.

I suppose the 5100's were already at max lift, right? Where did you get the springs and how much were they if don't mind me asking?

Re: Front 5100s w/ Trim Packer + Dobinson 1.6 inch rear

Right about 35 inches up front and 36.5 inches in the rear. The 5100s are set at 1.75. I purchased the springs direct from dobinsonusa.com and paid $250. I've decided that its too much rake and I'll be adding another RRO trim packer, or a single taller spacer, to raise the front up a little more.

Re: Front 5100s w/ Trim Packer + Dobinson 1.6 inch rear

Dobinson part number C29-125T normal duty spring. HD spring provides approximately 2 inches of lift on otherwise stock WK2 per Dobinson. I went and added another RRO trim packer spacer to bring up the front. Added another 3/8 inch to the front with just enough threads remaining on the strut studs. Still not level, but more acceptable to me.
