Frequently Asked Questions Link

Everyone has a different idea on what a rockcrawler should be so my chassis designs were made with customization in mind.

As you can imagine there are a lot of questions I have been asked over the years, I cover the big questions like drivetrains, suspension and tube sizing that are commonly asked about in the above FAQ.

Since I have personally built and driven my designs; I also provide links to the build ups which show virtually every facet of construction as well as analysis of the chassis after years of use. Feel free to use my builds as a reference point or to give you ideas.

Thanks to Matt Rust I can post the original build up articles that appeared in 4x4 Builder:

 

 

 
 

2 Seat Designs

Project BMP II

This 2 seater chassis was based off of the Project BMP 3 seater but the rear end was tucked in to give it a sleeker look.  All of the major dimensions were expanded slightly to ensure this chassis would be able to accommodate nearly any drive train. Click on the link above for more details

Hellraiser 2 Pickup & Hellraiser 2 Buggy

This 2 seater chassis is designed to have the lines of a pickup truck allowing for a lot of cargo room in the back if you choose to make a functional bed. A "buggy" version is also available.  This chassis design requires a rear mounted radiator or a small, angled radiator if mounting it up front.

 
 

3-4 Seat Designs

Project BMP III

This is the 3 seater chassis used for my Project BMP.  It was designed to fit a child sized seat in back to make a 3 seater or the rear seat can be omitted for a 2 seater with lots of storage.

Project Hellraiser 3

My latest 3 seater design here. This chassis design requires a rear mounted radiator or a small, angled radiator if mounting it up front.

Project Hellraiser 4

A 4 seater variant of my original Project BMP and what I currently drive. Seats 4 adults comfortably yet equals the performance of my smaller 3 seater design.
