I've had this truck since may 2016, I never had a shock end pull out till 3 weeks ago. I always replace the ends when they pull out. Front droop is at 106mm. I thought it was the lower arms flexing so I replaced them and that worked for 2 races. Yesterday I had another end pull out on the 1st lap. Always front shocks. Only thing different is chrome shafts this season. I thread the end onto the shaft just till it reaches the last thread. I had some viscous crashes last year(1st season w/ rc's) and never had one pull out. Anybody else having this problem w/ shock ends pulling? Oh yea, and I tried the mugen shafts and they bend as well, I guess if the arm flexes enough any shaft will bend.
