Dick Cepek Lift

I'm in the middle of a restoration and I've narrowed down my lift to the BDS 4.5 or RE 4.5 extreme. The Cepek lift on this jeep has been on over 100,000 miles and the springs are still tight, no real sagging. They are noisy because of rust between the leaves, and it will jar your teeth out (maybe because the shocks have 100,000 miles also) Any info on this lift? They are way cheap and have lasted a looong time. I still plan on the BDS or RE because I want a nicer ride with good flex and height, but I'm impressed on how well these springs have held up.

Way back when (~1996).....Cepek came out with there 3.5-4" SUA YJ suspension lift, they contacted me and asked if I'd be there local test monkey. I met with Tom Cepek at there old Kearney Mesa store & they sold me the lift at a reasonable cost (~$300) & installed it for free. I got the first one that hit the streets.

The lift was very noisy due to the inferior design and construction of the leafs. Since the leafs were not constructed with teflon pads, they not only popped, they squeaked as well. The spring clips were the type that held the leafs closely together. Again, bad design & caused for a rough ride under normal street conditions. Plus, with the front and rear tracbar drop brackets they initially installed, made for some serious suspension bind.

The shock tubes were an issue as well. Specifically, as the suspension drooped (ever so little because the leafs were so stiff) the shock tubes would contact the rear axle tubes & dented the shocks in short order. They were a double tube design, so no real harm, but you could hear them make contact on a regular basis.

The kit did not come with a drop pitman arm. Bumpsteer was aweful until I installed an aftermarket DPA, which afterwards corrected the bad bumpsteer.

It wasn't till after I installed a winch & swingout rear gas can & tire carrier that the suspension finally smoothed out some. Prior to that, it rode horribly. My youngest son Jerry would get carsick every time he rode in the back seat. I repeat - every time. Dramamine didn't help.

The first time I hauled it on a trailer and spent about a week in Moab, the suspension settled ~1.5".

So......what your saying is.... they may have sold the design etc to Rough Country?

I'm not familiar with DC suspensions... I thought they only made tires LOL

but... if the springs are still healthy, there are some things you can do to smooth it out a little and quiet it down some.

disassemble the packs and hit each leaf with wire brush on a drill to remove flaked paint & surface rust. Find a Tractor Supply (or similar) store and get some "slip plate" paint... it's a maint with graphite in it, often used for plows and other farm stuff to minimize dirt sticking and ease cleanup. paint each individual leaf with slip plate.

call a local spring shop and ask if they'll sell you (or even GIVE you sometimes) a few strips of teflon inserts... rather than a 2 1/2" square pad at the end of each leaf, these are full length strips of teflon you put in between each leaf.

with some heat (torch) and pliers, bend the crimp style clamps so they point straight up... then drill a hole through the clamp ears and put a bolt across with a piece of tubing on it, turning it into a bolt style clamp.

I did this on the rear Rancho leaves way back when I had an 87 XJ... night and day difference

if you've already got the height you're wanting, it's a much less expensive alternative, just the cost of the slip-plate paint, some teflon strips, a couple bolts and maybe some new shocks.

Thanks for the info. I think it was probably about 96 that this was put on. I always thought it was maybe the same builder as RC becuae of the cheap price, but I have not seen much droop as I hear RC springs have. After 100,000+ miles they will still jar your teeth out (or make you car sick). I think this has a dropped pitman arm, how long is the stock? I'm piecing together my upgrade and thought I have a dropped arm, I may have to buy one.
