Hate to give you more bad news, but the Integy bulks are the biggest pieces of @$#% i've ever purchased. I snapped the shock tower off them on the first crash. No joke. 5-minutes of run time and they were done. I'm not talking serious bashing, just flying around a racetrack at 2/3 speed (EVX w/Stock titans) and I landed off axis on a jump and it flipped the truck a couple times. No bending, it just "snap"ed clean off. Integy casts their parts then machines them. They are not billet. the gray plastic ones from traxxas are a better choice. If you want/need aluminum buy a pair from http://www.acncm.com/maxxfrbulk.html ($29.00pr) or http://www.fastlanemachine.com ($37.50 pr) both offer vastly superior strength to the Integy. Fastlane offers excellent customer service and a lifetime warranty. Just a reminder. Don not use aluminum body posts. The increase leverage (and increase damage) to shock towers & bulks.

If you have some cash to play with buy the 6061 or 7075 bulks from Great Assembly. They are the best ones on the market today. www.greatassemblyrc.com
