yes you will need fork extenders. if you order the rake kit from darrel at vtx extreme. he will have first knowledge of the fork extenders that you will need. i'm thinking i used 1 and 1/2 inch. but really can't remember.
the fork extenders go under the top cap. unscrew the cap, screw on the fork extenders and install the cap.
if you ever want to contact me personally. my email. is
honda1284@comcast.comfunny thing about the drive shaft. when i bought mine it was 140 or 150, somewhere around there.
now i see they are around 300, talk about inflation. but like i said before the honda ujoint works but it the way it is designed it likes to wear and goes into an eliptical motion if you can understand what i'm saying.
new system solves all of that issue.
plus the new system you can grease both front and rear joints.
plus you can replace the front ujoint. its put togather like a normal car ujoint. so you would never need to buy the whole yokes and everything. just the joint.
i've got over 100,000 miles on my new drive shaft and there is no wear in the splines and the joints are still nice and tight.
