From a previous post:
-Make sure the spring pads you use are GUSSETED. Spring pads that are just a folded piece of metal are dangerous in automotive applications. Gussets are a MUST!
Geez, here we go again. Oh please inform the uninformed just why this is so.
Is a 1/4" wall piece of machined tube steel a "folded piece of metal"? If you are speaking of the "Confer" or a "trailer perch", then say so, and we will likely agree. If you are making a statement in regards to the Breeze perch, then say so. If you are, then I have a big issue with your statement. There are far more vehicles running around in Canada with the Breeze perch on them than all others combined, and never a failure, and they have been on the market for a very long time, so they are a "tried and true" product.
Vague statements aimed at other products is not the way to win friends and influence people, or garner customer loyalty. Informative statements with clear consise information is the correct way to pass on information to the general public. So if someone is going to make a statement that something is "bad", then state the reasons why.
I am not and have not ever made a comment that the RRO perch is a bad product. It is well made for what it is, but is it the only safe way to do a SOPA, NO it is not, but some may be trying to lead the general consumer to believe otherwise.
Now, to answer the original question, with a 4.5" SPOA, you can get by reusing your old U-Bolts if they will come off (no rust damage). I don't suggest anyone reuses U-bolts due to their importance, and the fact that they tend to stretch more and relax once they have been previously stressed. With a 5.5, you certainly need a set of HD U-Bolts as the stock ones are just borderline in length, and you really need the thicker cross section. DS spacers and brake lines must be addressed as well. Yes, one can reuse the stock clamp plates, and flip them side to side and reuse the stock shocks, however this really defeats the purpose of trying to get more flex. We offer the basic SPOA in either 4.5 or 5.5 with DS spacers, new HD U-Bolts, four lower shock pins, and the four spring perch for $169.95. I will knock off for the lower shock pins if someone doesn't want them for now, but they cost more to add them in later once you decide to add the longer shocks. We offer sensibly priced products that are proven in years of service, and if our directions are followed, a trouble free system that provides a great suspension for far less than anything on the market.
