I know when I was searching the forums on this topic I didn't find a whole lot. So I thought I would post something for those who are (or might be) interested. I installed the L&P Center link and Double Sheer Idler Arm (DSIA) today. I took a few pics so those who might like to see what it looks like can see:
As you can see from the pics the system basically takes the stock center link and replaces the pressed in joints that wear out with 4 Teflon-lined hardened-steel ball-end bearings. The Idler Arm and Pitman Arm can be replaced as well with their double sheer design, which is very much like SLR's. You can replace both the idler arm and the pitman arm, only one of them, or just utilize their center link with the stock components. A nice set up if you are on a budget and want to piece a steering upgrade system together gradually. However in order to use the stock parts the holes connecting the IA and PA to the center link will have to be drilled out to 5/8". They provide two grade 8 5/8" bolts and hardware with the center link. Also available is an idler arm brace, but the Calmini one works (as seen in the above pics) so likely the SLR and AC ones will work also if you already have those. The install is fairly simple, but does take a good portion of the day if doing things by yourself. Lee and Phil (aka L&P) were very helpful and responded to e-mails within a reasonable time frame. From order to delivery was about 2 weeks. In develpoment is a set of bronze bushings to replace the OEM plastic ones. Here's a link to their website for more information:
http://www.lpperformance.com/Steering.htm hope this info helps anyone searching on this topic. In case anyone is wondering, no I am not a spokesperson for the company. I just feel that their product is good and wanted to present a first person review of the system. After I have some time to test it out on the road (and off) I will provide a "road report" if anyone is interested.
