         6 . The golf club head of  claim 1 , wherein said upper hosel component further comprises;
 an upper hosel component base, and   an upper hosel component tip,   wherein said upper hosel component base is formed out of said first material having a first density.   
     
     
         7 . The golf club head of  claim 6 , wherein said upper hosel component tip is made from a material having a density higher than said first density. 
     
     
         8 . The golf club head of  claim 6 , wherein said upper hosel component base further comprise one or more indents, and
 wherein said upper hosel component tip further comprises one or more tabs,   wherein said one or more tabs are adapted to engage said one or more indents to prevent rotational movement between said upper hosel component base and said upper hosel component tip.   
     
     
         9 . The golf club head of  claim 6 , wherein said upper hosel component base further comprise one or more tabs, and
 wherein said upper hosel component tip further comprises one or more indents,   wherein said one or more tabs are adapted to engage said one or more indents to prevent rotational movement between said upper hosel component base and said upper hosel component tip.   
     
     
         10 . A golf club head comprising:
 a body portion further comprising;
 a main body chassis having an upper hosel opening and a lower hosel opening,
 wherein said main body chassis forms a striking face portion that defines a forwardmost vertical plane, and 
 wherein said main body chassis further comprises a recess around a perimeter of said main body chassis, 
 
 a lower hosel component adapted to engage said lower hosel opening, and 
   a crown portion wrapping around a skit of said body portion at said recess of said body portion, forming an entirety of a crown of said golf club head,
 wherein said crown portion further comprises an upper hosel component adapted to engage said upper hosel opening, 
   wherein said crown portion overlaps said body portion at said recess of said body portion,   wherein said crown portion is made from a first material having a first density and said body portion is made from a second material having a second density, and   wherein said first density is less than said second density.   
     
     
         11 . The golf club head of  claim 10 , wherein said upper hosel component further comprises one or more hosel ridges located around an external surface of said upper hosel component. 
     
     
         12 . The golf club head of  claim 11 , wherein said one or more hosel ridges are located near a frontal portion of said upper hosel component. 
     
     
         13 . The golf club head of  claim 12 , wherein said one or more hosel ridges are located at locations that are equal distance around a perimeter of said upper hosel component. 
     
     
         14 . The golf club head of  claim 11 , wherein said one or more hosel ridges are exclusively located near a frontal portion of said upper hosel component. 
     
     
         15 . The golf club head of  claim 10 , wherein a forwardmost point of said crown portion is located less than about 17.5 mm away from said forwardmost vertical plane. 
     
     
         16 . The golf club head of  claim 15 , wherein said forwardmost point of said crown portion is located less than about 16.5 mm away from said forwardmost vertical plane.
