The XV product is a very good idea.
However, I think the demand has really gone down on the product with the arrival of the new Challenger.

I'm pretty sure the guy who runs XV is just a business man; not a designer.

Regardless of what the guy who runs XV is, these are the most detailed pics I have seen of the alum k member design, and how anyone can accept a non robust, non gusseted, stock material shaped, constantly reverse loaded, significantly stressed, non reduntant alum welded daily street driven high performance suspension piece is beyond me. It is simplely a matter of time before cracking in the HAZ welds occurs. Its a neat idea that will likely fail.

An alum roll bar would likely be just as practical.

As extra clarification to my :

"Non Robust"- Nothing heavy duty about it

"Non Gusseted"- no gussets`used to reinforce stressed connections

"Stock material"- off the shelf shapes, ie nothing custom extruded for the intended loads

"constant reverse loaded"- any material when loaded alternately in opposite directions fatiques much quicker then when loaded in only one direction

"significantly stressed"- a mopar K member is likely stressed

"non redundant"- if this part fails, very bad things happen quickly, not like say if one lug bolt fails

"Alum"- every grade of alum fatiques over time when stressed

"welded"- welding alum changes any heat treatment properties of parent material, and does so in a small area leading to a HAZ, leading to area likely to fail first when repeatedly loaded over time

"daily street driven"- constant use over less then ideal unforeseen surfaces

"high performance"- this is moparts

"Suspension piece"- see all above

I'm pretty sure the guy who runs XV is just a business man; not a designer. I'm also pretty sure that the whole XV product design came from under a Sean Hyland Motorsports restomod Mustang.

I have been in Seans' showroom and looked over the Mustang that sports a very similar setup. Also, he had several XV Challengers in various states of completetion at the shop.

SHM charges a minimum of $125,000 for a XV car, and up to $175,000. I have the pictures on my phone; just don't know how to get them off and post.

SHM had a body shop at one time building the XV cars, but that was closed up shortly after the new Challengers became a hit.

So, the quality issues are likely due to whoever is doing the work producing the XV components at this time. If SHM is still involved, the quality should be first rate.
