Replacing Bumper

We added a 4" bumper adapter receiver for hauling 4 bikes. After a years or so, we noticed that the bumper was deforming; this is after a CW service tech told us the bumper was strong enough.

With a good friend (thanks Kurt)... the journey begins for a stronger bumper... project photos to follow.
  • Thd bumper is a thin wall square tubing that any metal or welding shop should have or can get
  • The new bumper is .125 thick while the original was .06. Two openings were cut to fit what was a 10" extension.


  • I have seen these bumpers twist when adding buck racks to them. They are really not that strong, and the weight of 4 bikes and the bouncing is too much for them to handle. I installed a front mounted hitch on my tv and mount the bike rack to that. Cost was about 200 and about 45 minutes total installation time.

    Ready for the 4 bikes.


    Project Cost:
    - Tube: $73
    - Primer: $8
    - Paint: $11
  • Next project is fixing the outside kitchen door...
  • Where do you put the sewer hoses? I made a plate 1/4" to mount on top of the existing bumper. With the 2" bike hook up welded to it plus the tire mount. This gives tha bumper added support and NO twisting. My sewer hoses are secured in with 1/8" tent hooks. I drilled holes through the bumper and the rubber block, The 1/8" tent hook keeps the blocks in.

    I did a similar deal as you did on another trailer. But extended it 18" to hold a tool box and my batteries.
    Cheers all
    BUT a very nice job!!:B
