In regards to long travel setups, I noticed some used a boxed a-arm where others use a tubular or round a-arm. What is the difference, and why one over the other?
Thanks ....the kit is 5" over and we did pull the rear back a little but the front is stock We are doing a cost analysis as we speak to come up with a MSRP but more than likely it will be in the 5500.00-6000.00 rangeThat is one sikk set of arms. What are the specs of that kit? How much wider? What is the travel? Are they forward and back any? The last and most important what is the cost? Again that is a sikk set of arms.
I'm not sure that the comparison is meaningful in this situation. Perhaps 1" tubing is stronger than a similar thickness 1" square tubing. However, what we are talking about here is a boxed arm that I suspect ends up with much more area boxed than the equivalent tubing so it is quite likely stronger. The boxed design is also likly heavier if the thickness is the same. Ultimately, I would think it comes down to the design. Both can be made plenty strongdepending on the designRound tubing is Stronger than Square tubing. But Square tubing with the bracing could be more stronger than just Round tubing. But it would also seem to have to be Heavyier with the added wieght !!!
