I run a EX 400 rear on my Blaster.My blaster had a 250R shock on it when I bought it but I swapped it out for the EX 400. I like the EX 400 much better.More adjustment,Better ride,and increased ride height.Banshee front shocks work great with the EX 400.I have less than $100 into both my front Banshee Shocks($50 on ebay) and EX 400 rear shock($40 onn ebay.
