Getting ready to order an oil cooler for my 2010 WG and besides the cost issue one factor remains to be decided. The Anti-rotation device you get with the Jagg cooler is not mentioned with the HD cooler package. How many think the anti-rotation device is necessary? Is it an essential piece of hardware or not necessary. Have those who did not install one wish they had?? Will order either a Jagg or HD next week so would appreciate any comments.

 

i got an ultracool for $350 from dr. v-twin...the one with the fan. great item. i guess they have them for the wg.

 

just installed the older discontinued Harley Davidson "Jag" 10 row cooler. Anti-rotation is not need as the adapter facing mount has 2 ridges that fit on each side of the lower center divider. This keep the piece from rotating. Simple design that has less parts and cleaner look than the Jag. BTW, the older HD can be had for around $200 on Ebay. I like the extra oil amount too. Could just use 3 quarts instead of the 2.5 without.
