If I could rate this product any lower, I would.. They look the part but the oil retention i.e. seals are recycled rubberbands. Do not waste your time and money on these Lego shocks.

TL;dr: Proper scale looks and function, but re-build them with o-ring grease before use.

I installed these on my TRX-4 Bronco out of the box with 40wt oil. Immediately on the first trial, they leaked profusely.

I normally re-build these shocks at first, specifically RC4WD's offerings, so you will need to do the same before filling them with oil and running them.

Build quality is good, with typical RC4WD fit and finish. The aesthetics are spot-on for scale looks. The spring rate appears to jibe with the weight of the 324mm TRX chassis with typical accessories installed and a spare tire.
