2001 and 2002 Big Hit frames are all the same
Except the 02 Big Hit DH has an 8" linkage
which is a linkage plate and a loger stroke rear shock
All 01 and 02 frames are upgradable to 8" using this DH linkage plate and DH shock
i think RRP is about $1200 (if i remeber correctly)
The 2003 Big Hit Comp is the same as the frames above and you can upgrade it to 8" using the linkage kit for the 02 Big Hit DH, This linkage plates has 2 setting 8" and 7"
The 2003 Big Hit Expert, Pro, DH are all the same frame they have 8" of travel, BUT YOU CANT USE THEIR LINKAGE ON THE MODELS MENTIONED ABOVE
this linkage is slightly different.
The linkage on these models has 2 travel setting 8" and 6"
I hope that made it clearer i hope :?
which frame have you got and what do you want to do with it?
