BDX Bumper Cracking Tunnel

sledhed88 · Mar 9, 2009

Has anyone had there BDX Bumper kit snap there tunnel in half basically. Me and my buddy installed the kit back in the summer, with minimal use both tunnels have started cracking at the bottom rivet in the rear foot rest on both sides. Cracks go straight vertical. Rear halfs on tunnel are junk now> Will post pics later on

Jeff, see if you can post a better pic. I can't see how this relates to the bumper. (just can't tell from that pic)

yer tunnel wasn't exactly "stock" to start with though, could this have been related at all?
Of all the kits that people run that Brian did I've not seen one cause problems aside from where the new cooler support brackets were added last year.

mine cracked vertically just behind the r foot rest.right on the back edge where it lies against the tunnel.i fabricated up some support plates and rivited inside my tunnel and drilled a hole at the end of the crack.its a pretty beefy set up ,
but when stuck and lifting the rear bumper, there is still alot of flex movement.

Broke mine on one side. never bent it up or broke other side though. Reinforced the broke side on the inside with a aluminum plate. I will probably replace the rear tunnel section this summer and fishplate both sides before I ride just to make it stronger.

christian,

How did that happen? Did you land on the bumper or were you just lifting it?

I was just about to order a BDX now I am glad I bought the VE!

Mine is bending where yours cracked and is cracking where the flap connects.

Overall a nice mod however in my experience all mods compromise the sled is some aspect.

A guy has to wonder if this will be the fate of the 09&10 stock sleds as the tail design is very similar??

coming of the top....wheeling pretty hard.

I compared mine to a stock 09 and the bumper goes past the running boards... bdx stops just short...

regardless I am 160 pounds dry...we gonna see a lot of these break or maybe I'm just an ****

This is why I am building my own, Like the vanamburg but incorporating the rear kick plates. I guess they should extend the riveted kickplates and tie into the back section of the tunnel a little further back? But it would just bend there! I am sure a stock tunnel would have kinked with that much of a whallop! The inside would be a good place to reinforce, But then the tunnel could buckle in the first half? I was just lookin again, If they machined a boss on the rear kick plate that you could rivet the rear bumper to, It would make it a much more rigid box section.

mines crack on the left side, gonna get tig welded tomorrow before riding-leavin thurs.

high_psi · Mar 9, 2009

I've got an 08 m1000 a tiny crack is forming on both sides making plates to stop it from ripping off, that looks nasty christian.

1Mike900 · Mar 9, 2009

Sledhead, I am guessing that we are looking at the inside of the tunnel, And that is the cooler line that is bent?
