The SSD Trail King Pro Scale Chassis Builders Kit was developed to offer discriminating scale builders a more effective weapon for their arsenal. The Trail King offers a level of scale realism that has never been available in a box stock kit - until now. By combining their proven, high performance option parts with an array of unique parts that are only found in the Trail King, SSD has raised the bar and created a kit that can be effectively utilized by scale enthusiasts and performance oriented crawlers alike.

Scale Engine & Transmission Assembly   
The SSD Trail King includes a first of its kind multi-piece molded plastic V8 engine that is complimented by a scale transmission and transfer case assembly. The scale engine houses a forward mounted motor and each component is meticulously modeled as close to the 1:1 parts as possible. The engine is made up of 14 individual pieces, and with a little creativity can be detailed and modified even further. Plus, the transmission holds the motor extremely low in the chassis, providing a lower CG and increased performance when compared to motor forward configurations from other brands. 

Offset Pro44 Front Axle   
By using their proven Pro44 axle parts, and combining them with a unique offset axle tube configuration, SSD has designed a scale axle housing that is durable and lightweight. The axle tubes are one piece, so they eliminate the link mounts and associated hardware that shows in the front of the axle - creating an incredibly realistic looking, lightweight axle housing. The axle is finished off with machined aluminum c-hubs and knuckles, 6 bolt locker/ring gear assembly, and hardened steel offset universal joint axles that allow up to 50° of steering throw!

Hardened Steel & Titanium 
The Trail King is a true premium level builders kit. With high quality precision machined parts throughout, the kit is guaranteed to impress even the most demanding builders. From hardened steel machined gears and driveshafts, to the titanium links and SSD Pro Scale 90mm shocks, this kit is fully equipped out of the box. With no need to throw a bunch of upgrade parts at the truck, you can focus on choosing the body, wheels and tires you want - and build a truly unique, high performance scale truck.

SSD RC Trail King Pro Scale Crawler Chassis Builders Kit
I’ve built many kits. But this was my 1st crawler. Easy to build!! Only down fall is the motor cover. I bought Rc4wd pulley kit and other parts to complete motor, to find out everything I bought doesn’t fit. Motor cover to small. But easy fix, have to buy RC4WD motor cover. Other then that this crawler is great! It handles so much better then my friends SCX10 II. I’m glad I chose this kit over SCX10 II.

SSD RC Trail King Pro Scale Crawler Chassis Builders Kit
This is the nicest builders kit I have ever put a wrench on. Everything about this truck is top shelf. Plus, it has more steering than any other SCX10 based truck out there. The motor is hung super low, and the truck is incredibly light weight. If you are looking to build a scale truck, or go crush big boy lines - the Trail King checks both boxes. Nothing out there even comes close. After building the kit, I was surprised it didnt cost more... 5 stars all day.
