When shocks leak or lose caps, performance suffers—and the ARRMA ARA330665 set ensures you get back control. The composite caps maintain structural integrity even after frequent crashes, while the O-rings help prevent oil leaks, preserve damping, and keep handling sharp.
How do the ARRMA ARA330665 shock caps improve durability?
Composite material is more resistant to cracking compared to thinner plastic parts. With ARA330665 caps, drivers benefit from parts that absorb impacts without shattering, making them especially useful for rough terrain, high jumps, and when pushing machines hard.
Is sealing and leakage addressed?
Yes—leaks at the cap cause oil loss and reduced damping. The included 11 × 1.5 mm O-rings in the ARA330665 set ensure tight sealing. Assembling correctly maintains oil levels and shock performance, preserving ride quality and handling over time.
Where are these caps intended to be used?
These shock caps are designed as spare parts for the ARRMA ARA330677 and ARA330678 shocks. With exact dimensions and O-ring support, they are direct replacements that restore your shocks to factory performance.
