abu power handle?

hi all just a quick question i have a abu5500 c3 ct mag and was thinking of putting a power handle on it,
would this put too much strain on the real under heavy load or would i be best sticking to the original?
any help would be great thanks

will be fine , all the internal parts are the same anyway , and because the 5500 is narrower than a 6500 its it a stronger reel by its very design

cheers ag thanks for the help man
