So got the rear bags replaced this week with some Westars & then the front decided to actively start leaking off. Since i did just do the rears I'd prefer to not chuck it all & convert to springs if i can avoid it. Looks like the fronts are Westars as-7300 & as-7301 which have become harder/more expensive to come by. rock auto has the westars at $460 range, but also lists ultra-powers w/ same part #s for $280 range. are the UP acceptable quality or simply a waste of $300? Dont know anything about the brand
