I bought a front and rear set of BQLZR shocks for my XB off of EBay recently, and have been super happy with them so far after 2 months of run time. The springs are stiffer than the stock shocks, and so far no blowouts or leaks! They are really well made, and the best part is they only run $20 a pair. You can buy them in different lengths and colors, and they come with all new hardware for mounting. The only thing you have to modify to fit them is to drill a larger hole in the shock tower for the upper mounting hardware. In my opinion, you absolutely can't beat them for the price!
