Typical Lead Time: 4 – 6 weeks
The Wide Open Design Evolution Rock Crawler chassis was initially designed for trail riding and competing in various forms of off road racing. Strength, space and style were all thoroughly thought out when designing this chassis.
The demand came for a smaller “Hill Killer” style chassis like this one. While keeping true to our roots, we wanted strength and style in this rock crawler chassis. We knew we could give up a little space, due to the type of use this buggy would be built for.
Along comes the “Evolution Chassis”. Our 50″ wide 2 seat chassis for the folks that like to beat down in the woods. We incorporated many ideas from our other buggies into this one. Built for big horsepower, full width axles, big tires, and hill killin’. The Evolution has a more laid back A pillar, a much shorter rear end, slightly shorter front end and over all lower roof line.
Hammer Down for Longer
Our Heavy Duty (HD) design places 1.75 x .188 wall tubing in the high impact areas where extra strength is needed.
A chassis built entirely out of .120 wall tubing will keep occupants safe in a roll over, but leaves the chassis vulnerable to getting dented and bent. The increased strengthening of a few key impact areas allows the chassis to have a better chance of remaining straight and is less likely to dent from sudden impacts. A heavy duty chassis only adds a minimum amount of weight and you’ll have a chassis that will hold up for years to come.

Sides are Protected with Replaceable .188 Tubing Rock Sliders
| .188 wall rock sliders act as protection to the sides of your Rock Bouncer. They also double as a step to ease entry and exit from your buggy if you have not chosen to have doors installed. We’ve built these into the chassis that if they do get beat up, they can be easily cut off and replaced with new .188 Tubing |  |
Adequate Rear End Room for Fuel Cell and Tool Box/Cooler
Easily fit a 15 gallon fuel cell and a fabricated tool box in the rear end. Have fun trail riding and bring along a few tools that you may need. Or use the tool box as a cooler for your beverages and food.
Install and Remove Components with Ease
| Removable Crossmembers allow for easily installing and removing of drive train components into the chassis. These tubes are connected using our Tube Flange sets. |  |
