A lot of people were interested in the anti rattle kit I have placed on my bike rack that actually works . It keeps the rack from moving around during transport. I spent a lot of money on the bike rack only to find out that it was the norm for a bike rack to jump back and forth with the bikes on it while driving down the road. several years back I invested in a curt bike rack that holds 4 bikes so I could transport the bikes for the whole family . The rack wasn't cheap and was very well made with the exception of the tie down system. The only problem was it simple moved around in the hitch  when in use and I would see the bikes bouncing up and down the entire ride.

It made me nervous and I was afraid the bikes would come free or damage the car or trailer. I contacted the MFG. Curt and they said that this was the norm there had to be some play in the tube for it to slide in and out. after talking back and forth they sent me a replacement bar several times only to slide it in and find out it was the same disaster waiting to happen. I finally told them I couldn't keep a rack that worked this way and they told me to bear with them for a few months and that I wasn't the only person that had complaints. fast forward 3 months I get a neat little package in the mail for free and had a letter apologizing for the problem with my rack. they took all the customer complaints to the tech people at curt and invented a really simple solution and called it an anti shake or rattle kit which is now available in many stores and online for less then $20.00. The biggest part is it really works.

Once you use the kit you will say to yourself why didn't I have this before. Its really simple to use its basically a threaded high grade case hardened hitch pin with a special slide in nut that sits inside the tube. when tightened down it stops the tube from being able to move in the hitch.  You can get lots more info from Curt's web site  curtmfg.com , specs and where to buy. Here are a bunch of pics of my rig with the bike rack in use  and pictures from curt , also picture of instruction sheet. It comes in 1 1/4 or with the block to be used in a 2 inch hitch so can be used for both sizes just have to buy the one you need.
