Hi. I had bought a set of 4 Xtra Speed Aluminum 95mm Adjustable Piggyback Shocks For Axial SCX10 last Saturday. I had found out that one of the shock oil reservoir tank thread are not deep enough, and it had pop out when filling with shock oil. I was wondering can I take it back for exchange with in the next day or two? Due to I will be leaving HK for business trip this Wed morning. Thx and hope to hear from u soon!
