Tom-Arneon RC4WD King Off-Road 1/10th Scale Piggyback Shocks w/Faux Reservoir (100mm)

Great looking shocks, and thats about it. Really tricky to change oil on them, and even if you make it they dont perform well at all. Should also been delivered with a single spring setup, because the ring between the 2 springs sometimes get stuck on the bottom of the shock body, and also catches a bit on the threading on the shock body.

I bought this for use in offroad element. the middle ring between the springs get often stuck because of sand or dirt. Not for me. Other than that it was ok product.

Rich HomanVerified owneron RC4WD King Off-Road 1/10th Scale Piggyback Shocks w/Faux Reservoir (100mm)

Had these installed for a month. The performance was ok at best, they get hung up at full stroke. After a 4 hour trail run 2 of the shafts had worn down to copper. One the shocks had lost all of its oil and inside had gotten a bunch of dirt. After replacing the seals and rebuilding both shocks the new seals still wont hold oil very well and until I replace the shafts oil will continue to leak through the seals. Sad because they look amazing and were one of the aesthetic things I really liked about my rig. But after spending close to 100 bucks for a complete set it feels like they will end up as paperweights on my desk.

What reviewers say

Reviews are mixed, averaging roughly 3.8 out of 5. Reviewers praise the appearance of the piggyback reservoir design. Several report the middle spring-retaining ring catching or sticking with sand and dirt, and suggest a single-spring setup would be preferable. Two reviewers describe poor performance, hanging up at full stroke, and oil leakage; one reports shaft wear after a single four-hour trail run and seals that did not hold oil after rebuilding. Two five-star reviewers report good performance on an SCX10, one saying it runs dry with green slime-type lubrication. One reviewer asks about fitment on a Losi Baja Rey, and no reply is included. Oil changes are described as difficult.

  • + Attractive appearance
  • + Good performance per some verified owners
  • + Reported to run well on SCX10
  • − Middle spring ring sticks with sand or dirt
  • − Hangs up at full stroke
