[GorillaMaxx360]

zeropointbug i have asked this question before because i have a FLM chassis and i am pretty sure they told me 72mm. also 72mm is stock for the front the only difference in the gmaxx chassis is the extended rear the front is the same length same with the FLM chassis it is only extended in the rear. the 72mm should work because it is made to replace the stock part that is standard length. wait just to be sure or pm serum or one of the other guys that are high on the totem pole they should be able to help, but i am pretty sure it is 72mm that mike sells.
