I bought my granite BLX 4x4 on July 30th of this year and all 4 shocks are leaking after like 8 battery packs. Should I bother with the warranty process or just rebuild them, which would be much easier than shipping things. I'm not sure even sure if I have to do that. If I do rebuild them, what oil brand and weight has been proven to be the best for bashing? Thanks! I want to know the oil info anyways.
