I got some rear lowering blocks installed. Question is are they suppose to be drilled and tapped on all four points that bolt up? Mine are only threaded at 2 spots.....the directions say they may need to be tapped. Well !*$# they both need it I think.

 

What brand are they?

 

I bought some from Arlin Ness and no tapping. One thing I do is set them on hi setting for two up rideing.

 

Sounds kind of odd. Do you have any pics, or what kind are they? Mine had only two holes, both were tapped. Kit came with four new bolts, two per side.

 

Came with 3 bolts. Maybe it's just me reading the directions wrong.....I think I might take them to the Indy and them just tap the other holes and be done with it.

 

I got mine from Tamarack. Easy mount, 15 minutes...

Included 3 bolts, you reuse one stock

 

I got advice from bosken and went with tamarack...Great Company. i think i posted on your earlier thread about lowering blocks that they were a good company to buy from. Mine came with all 4 holes tapped and 4 bolts... I used the two shorter bolts on the front of the block to attach the block to the swingarm where the bottom of the shock usually goes and the two longer ones where the bottom of the shock is relocated to the back of the block. It took about 15 minute for installation.

 

I also got mine from Tamarack. A very nice product.

 

Yeah I got the Tamarak ones. 1 hole on the right side block is not tapped....I got through on there web site and might just call them tomorrow.
