We have these lines custom made for us using the best stainless braids and teflon-lined hose we can find. Lines come in a pair w/ new crush-washers and retianing clips. We sell them in 19" and 25" lengths. 
-Any kit using a stock spindle (including Titan Swap) should use the 19" lines
-Use the 25" lines when using a spindle-lift or drop bracket kit
