Nice. Glad to have these being made.

No one mentioned it yet, but a bad fix on pre-hydrualic fed tensioners was to use a fixed tensioner (modded with a bolt to be fixed). This sort of fixed the short term problem of the tensioner collapsing but negated the entire reason for the tensioner which was to allow the chain to move under thermal expansion.

When a fixed tensioner is used on a street car, massive force is placed on the idler shaft and chain housing. On my 2.7, the idler shaft actually worked its way out the backside of my housing due to solid tensioners. The soft mag chain boxes and old JB weld material was no match for the stresses of the steel shaft wobbling back and forth.
