Making the Pedders ZL sway even better
For a little background I bought the FE4 ZL sway about 4 months ago. It performed well but I kept hearing some knocking when the rear suspension would cycle quickly due to small bumps, holes etc.
While doing an inspection after a weekend at the track I noticed the sway bar bushing was loose inside the bracket. Here are some pictures of how I fixed the problem First a look at the original part you can see that there is play in both lateral and vertical directions Here is a good view of how much play is on each bushing Here is the new aluminum bracket and solid bushing from Provenwicked.com Close up, you can see these are some Bad _ss brackets ;-) These are actually designed for use as part of the Proven wicked rear FE3 sway bar but with a few modifications it can be used with any 1.25" bar. As you can see the factory bolts don't fit and must be replaced. Some 7/16ths holes and the new hardware drops right in I'm using 12.9 allen head bolts because a socket wouldn't fit into the bracket bolt holes and should be rated about 25,000 psi stronger than the factory bolts. Some test fitment to get outside edge measurements for locating the bearing Measures 28 1/4 from outside edge to outside edge The locating tabs on the Pedders bar is 25" apart so subtracted that from the 28 1/4 measurement and each side needed to be located 1.625" from the tab. And here are some final shots. They have ZERO play vertically or horizontally but because of the bushing design they will allow the bar to flex (Bow) and twist as anti sway bars are designed to do. And no more NOISE! Last edited by jeremywes; 12-20-2012 at 07:42 AM. |

That looks sweet. I'll have to check mine. I haven't heard any noises but better check anyway. Thx for the write up.

I have my bars coming soon! So this seems like a reasonable thing to do out of the gate. Do you have any links to the required parts for the Google-challenged?
I am not Google-challenged, I just hate buying the wrong parts because I assumed I understood what I needed to get. Thanks! |

jeremywes, I am so sorry you encountered this issue. We have Special bushes for the FE4 / 5 / 6 Brackets that fit perfectly. The bushes you had were for FE3 brackets. Your solution obviously resolved the bush / bracket fit issue. Please drop me a PM and let me know what other suspension bits you may need or want. I owe you a special discount for your troubles.

Thought you should not use that bar on a V6 car because of possible caliper rub???

Phew, good to know. Didn't seem right that Pedders would ship a bar with a bsuhing that mated poorly with it. I'll be sure to check mine as soon as I get. I'd hate to realize it during the install!

We are not ready to say the Z bar is 100% approved for use on a V6., but our revised Z bar looks like it just maybe good to go on a 6. |

I'll throw in my experience with the same type of issue. A condensed version of the story is that I put on the Pedders ZL1 bars and ended up finding the same issue as the OP had. After calling up Pete and working with him one-on-one about the issue he determined I had the FE3 bushings but I had switched out the FE4 straps without his or my knowledge. I had bent my original OEM straps and got some new ones that I thought where FE3 straps...come to find out they were FE4. For what ever reason there is about 1/8" difference between the FE3 and FE4 straps. So, it's very important to know which type of straps you have and which type of bushings you have Pete send to you. Also, as Pete as mentioned before....if it's not a perfect fit then something is wrong and you should contact him to help find out the problem.
**No need to pay for aftermarket straps***
