Teraflex fiberglass leaf springs

[heavyarms642]

Personally, I have been waiting for something like this for a long time. For those of you who have not heard about these yet, Peterson's 4 Wheel Off Road magazine did a pretty good review http://www.4wheeloffroad.com/techarticles/suspension/131_0702_jeep_yj_fiberglass_leaf_springs/. What does everyone else think about these? If they can hold up to some punishment, I would swap over to these things in a heartbeat. Gives me a good reason to do that axle swap WooHoo! :pbj:

There's someone (vettej) on page 2 of this thread that claims to like 'em.

I personally don't know the fella' but he's got a good attitude. :rolleyes: :nutkick:

The monoleaf design is a limiting factor in my mind...
Everyone thought that when Skyjacker came out with the monoleaf 6" lift it was the wave of the future... and no one runs that setup due to sagging springs that bend very easy. Just my .02:sniffle:

Wanna take a wild guess at who had their fingers in designing/testing the first Jeep monoleaf lift kit? ;) As a hint - it wasn't Skyjacker.

Materials engineering has come leeps and bounds in the last while, so I think these springs will work well. However as with any leaf pack sagging come be any issue.

I don't think the skyjacker 6" monoleaf was the greatest idea due to it being SUA and that left A LOT of spring exposed to getting damaged.

Has anyone seen a price yet? I looked for a bit but didnt see anything, I'm at work so can't spend much time looking.

[rockjeep]

You should see them when they wrap to much and break. The fiberglass splinters are great to deal with.

[--jeep--]

does anyone know how much axle wrap you get with these fiberglass springs is it minimal enough to not run a traction bar? would the RE 1.5' reverse eye 6 leaf packs be better than the tereflex for wrap?

They wrap real bad. And yes the re's are better

[heavyarms642]

Thanks for the link Joe.

Rockjeep - What makes you say they wrap real bad? Have you had experience with composite leaf springs in general, or the Teraflex springs?

[rockjeep]

I tested the first ones and broke the rear springs right at where the ubolts are in front of the axles. Traction bar is a must. with multi leaf springs as the wrap they allow slipage between the packs.

I think the fiberglass leafs once refined..(which they seem to have there crap together now) will be a better end product. I haven't personally tested these leafs but i have seen / worked on corvettes fiberglass leaf and never seen one break, sag, chip, crack etc.. also i know a ton of people running composite leafs on syclones and typhoons that are running low 10's and 9's and never heard of those guys breaking them.

I've personally bent a leaf pack on a SUA setup S10 behind a blown motor in it with traction bars on it and watched another S10 that was a mid 11's truck run no traction bars, no nothing but shocks (3rd shock) and slicks and never break or have any problems before he got his ladder bars back on.

Doesn't say anything for how they handle being drug down rocks of coarse lol but as far as axle wrap etc i would say if they are breaking then its just not a good design on their part and someone else should design the composite setup.

I called a guy in Azle, Texas that could get them and he said that they run about $230 a pop!!! I'd like to wait till more people use them before I buy.....

Later

[brock1949]

ehh, 230 ea seems a little rough. I would love to try them but i don't think i'll be first inline to spend 1000 bucks to test them.

[James (Cubby) Culbertson]

Certainly a case of "don't buy the first year model" eh? I remember the monoleaf was going to save the world and that one died a quick death. I'd wait until the jury comes back to be honest. At $230 each x 4, you could get probably 6 sets of Alcans and be plenty happy.

The corvette is not a good compair. I have one on my 68' corvette and love it. It runs parallel with the axle and doesn't see any axle wrap, nor the type of travel we are trying on the jeeps. In that aplacation it works perfect. The other examples you cited are bad ones also. Small amount of travel needed and almost zero frontal shock load. By shock load I mean when you hit a rock going foward and the force is transfered through the spring this is what usually bends the spring near the rear eye. was that 3rd shock fashioned in the same mannor as a traction bar?
