The 6 Best RC Rock Crawler transmissions (2023 reviews)

The benedict rc rock crawler transmission is long-lasting, rigid and fits well with your daily purpose like a dream.

The gears are 48 pitch so you may want higher pinion gears. It can be swapped out easily. It comes with a front aluminum protection cover. It is used for 2 seasons with no problems. This will fit on any 3 gear axial chassis / skid plate others may need some modification.

Best Quality Transmission: RZXYL RC Rock Crawler Transmission

Buy on Amazon

The rzxyl rc rock crawler transmission is capable of outshining several other transmission featured in this list in overall features in its price range. It fits perfect with a scx10ii hole pattern. It has standard 4 bolt patterns as most 3 gear transmissions if not you would have to either drill holes to make something to make it fit. It does come dry so you will need to geese the gears which is very easy to do. It has all plastic gears and will definitely crap out on you sooner than later.

The body is smaller on this transmission than the original so the longer driveshaft extensions are needed. It comes with a slipper clutch too.

Why We Like This:

More plastic spur or chance of sand killing your pinion
A beauty and gears and bearings very smooth turning
Proof, has slip protection, which can protect the gear

Best For Wraith: Benedict Harry RC Rock Crawler Transmission

Buy on Amazon

The benedict harry rc rock crawler transmission is capable of outshining several other transmission featured in this list in overall features for the price point. It is perfect for a wraith as an upgrade, internal steel gears, and works perfectly with a 2300kv on 3s, running 13/56 gearing. Due to the design of the gear engagement, there is a noticeable increase in gear play when rolling the chassis back and forth. The inner diameter of the bearing race tolerances are ( give or take) 1mm off and causing the slop. The transmission shifts perfectly fine while moving. There is a shifter on the case. It works well but must stop to shift or will break the low high gear rod and the only high gear to replace low high rod.

Why We Like This:

Holds up to a big brushless motor on 2, 3 and 4s
New and hot release
