"Blaster shocks makes nosebleed suspension height increase. May cause interference between rear brake rod and passenger pegs. Drastically affects trail, may require taller front end, depending on intended use. Upper bushing requires sleeving to use TW mounting bolt. Despite its length, factory-limited travel only midway between stock shock and Banshee. Potentially the best ride quality across the board of the 3 (in stock form) due to spring design, but this spring may be too soft intitially when used with restricted travel.
Newbies need to understand that a 2" longer shock does not result in a 2" taller bike. Rather, it results in a 5"-6" taller bike, but only in the rear (swingarm 'leverage ratio' @ 3/1 davedyno) . This shortens your wheelbase and brings your front forks more nearly vertical, which among other things can result in twitchy handling and poor impact absorption up front. Everthang affects some other thang."
