While many said no or recommended other mods, I received some great info which led me to H&R 1" springs paired with Bilstein 5100 shocks. Over the Thanksgiving weekend, I purchased a set of H&R 1" progressive springs (part # 52107) and Bilstein BE5-785-HO and BE-784-HO shocks. I had planned to do the install myself, but with work, cold weather, and other interests, I decided to let the local 4x4 shop have at it. Took them 3 hrs and then off to the alignment shop.
Picked up the Jeep yesterday. After approx 10 miles of driving, I would say the ride is great. PO had installed Edelbrock shocks with stock springs. I was pretty sure one of the rear shocks was bad and the overall ride was very soft. I have a much more firm ride now, but when I hit bad pavement, I can feel the suspension system doing it's job. I need to obviously drive it more to give a better evaluation, but first impressions were very positive. As expected and planned for, no vibes at any speed.
So did I get any lift? Measuring in the dark last night, it appears I gained 1.25" in the front and .75" in the rear. I'll confirm those measurements again once I have some light. While I only have a soft top, I do have a back seat, spare, and the back was loaded with the old springs and shocks. I thought my Jeep was pretty level at stock, but after the new gear was installed, it still seems level. So maybe the difference in lifting heights helped me. Who knows.
Can you tell a difference? I can. It's subtle, but just enough for my liking. I think it's just enough to make the 31s look proper. I'm happy.
I know this sucks without pictures. I promise to post some once I have light and some time. So for now, here is the only pic I have prior to the work being performed.
Special thanks to Fargo and Hustler905 for helping me find and match the H&R and Bilstein parts.
I measured again yesterday and confirmed 1.25" front and a hair shy of 1" rear. And it does ride great, but I want to drive it awhile and give a better report in the future.
I think shocks and springs cost me approx $500, maybe a little less.
My research leads me to believe all H&R springs are progressive. In appearance, the ends of the springs turned into themselves and the diameter varied. I thought that was an indication of being progressive, but maybe I'm wrong.
In the end, I accomplished my goal. Replaced my suspension components with high end parts, got a great ride, and got a little lift along the way.
please post a picture soon... I have an 04 TJ and will be putting a new set of BFG 31's with some black wheels on in the next week or so. I have also been poking around for a 1" lift, just enough to help with the added tire dia, but keep the ride good as this is my daily driver. Were you able to get the springs online or did you have a local store??
Concerning installation of the shocks, front and rears were installed with the boot up, which was opposite from my previous shocks. I spoke to AJO, who told me if Bilstein was readable, they were installed correctly. I didn't like that answer and called Bilstein directly. They told me boot up for these shocks and application.
