Took my Jeep to the Silver Lake Sand Dunes in MI this past week. Great trip and I love the sand, but this is my first trip after my lift.
First, here is what i have: 03 Rubi, 4" Rock Krawler X-Factor long arm lift, Bilstein 5100 shocks, 33x13.50x15 tires. A very nice set up and I love the ride on road. The flex is great as well, but with myself, my wife and 2 kids in the Jeep as well as a small cooler with drinks and snacks in the back, when I hit much of a bump at all with much speed, I bottom out in the back. The front performs perfect. Actually, when we are all loaded up sitting still, I lose about 1/3 to 1/2 of the distance from the top of my rear tire to the fender flare. With the 4 of us and a cooler, we are about 650 lbs.
My bumpstops are right as are my shock lengths. As a matter of fact, I have a couple very small spots where you can see the top of my rear truss has bumped my exhaust pipe. My jeep sits slightly low in the back, but I figured that when I put a winch on the front (that cash went into the pool house this spring, but that is another story
) my Jeep would sit level, problem solved.
I was wondering what your thoughts were. I am not an expert on the relationship between shocks and springs. One thought is a slightly longer spring. Another is an adjustable shock that I could stiffen for the dunes. Another is the spring relocation brackets that AEV sells for the rear to gain an extra 1.5" and level the Jeep as well as straighten the spring. My last is AEV's progressive coils. Of course, I am open to all other thoughts which is why I am asking here.
If any of you have ever been to the dunes, the bottoming out can be pretty harsh at times and I would really like to have the suspension absorb the load vs. the bumpstops and shocks.
Thanks so much for your advice!!
