RC4WD King Off-Road Dual Spring Shocks (120mm)
Initially I was impressed with this shock, it looked great, I filled it with 32.5wt oil and it felt good and perfectly damped and were silky smooth with no oil leaks. The first 3 weeks that I ran them I was so happy and I thought about buying more...after that I noticed some graining on the shock shaft and then another few weeks later the coating on all the shock shafts started flaking off which also ruined the rubber O-rings. So these shocks are useless to me now, I am not willing to spend more money on the replacement shock shafts and O-rings only to have the same thing happen again and waste more money. This is the first shock that I have ever owned where I had the shock shaft coating flake off like that.)
