If mild steel and chromoly were the same thickness and size they would both weigh the same, but since chromoly is stronger they can use a smaller and thinner wall tubing, so it weighs less. and with the difference in weight the old welder I went to probably is wrong, like you guys say Hot-seat couldn't stay in business long. My apologies to Hot Seat for telling about what the welder said.

 

Are you sure it isn't an Aaen extended swingarm? They have you send in your stocker and stretch that. Instead of the custom unit Hot Seat sells. [img]i/expressions/face-icon-small-smile.gif[/img] Both of them work great.....just one is quite a bit lighter than the other.

 

Modquad, The 2 1/2" is your old swingarm, You have got the 5" I had that I got directly from Hotseat
