Reply to "Quella Aluminum Koni Shocks"

I'm sure the Konis that Quella sells are high-pressure gas charged, and as such have the capability of working longer and harder than 'regular' shocks, by avoiding foaming of the shock oil inside. Gas shocks can also be mounted upside-down both for convenience in spring-height adjustments, and a small amount of unsprung-weight reduction. The aluminum shock bodies are each 14 oz lighter than equivalent steel bodies (according to Quella), for a considerable price increase. Your call there. The double adjustment (jounce & rebound) feature is nice but 99% of owners set them up once and never again touch the adjustments. Konis are rebuildable but its seldom needed unless you actively race. There are 30-yr-old Konis running around on street cars with no leaks.
As others have said, proper wheel alignment is key to enjoying a wide-tire Pantera, and stock alignment specs will not allow that to happen. Feel free to experiment- at low speed at first- but start with twice the stock amount of caster adjusted into your front end. There are several ways to do this, not all of them expensive.
