What are you encompassing when you say it’s the same construction?
These for sale are the xta plus 3. Xa is only rebound adjustable, these are low speed compression, high speed compression, and rebound adjustable, internally they are very much different products.
Aside from having added NVH due to the top mounts if you run the same spring rates on a xa and say this set once tuned and adjusted right you could have a more comfortable and complaint ride on these than xa’s if that was one’s intent with how they turned the adjustments. A good adjustable damper is beyond alarming how drastic the change can be from full soft to full hard, so having the adjustability allows the valving windows to go beyond what the xa’s are factory set with for compression in regards to softening that is.
