2017 ULTRA4 Schedule Announced

View on Facebook

Rolling out of the shop this week is an EVO Grunt AT with the Cliffhanger front end and suicide doors. It's a simple build with Toyota axles using our BFR Toyota bracket kit and an old school ZZ4 first gen small block Chevy / TH350 / D300. It sets here at full bump on ORI struts (14" front and 16" rear) direct to the axle and 36" TSLs. It prooves you don't have to put together a crazy parts list to build something and have fun!

What can we build for you?

Some of you that are paying attention know I have a new chassis called an EVO3 that is designed for speed, and that I have one that's already started that you can spot in the background of some pics.

With the owner planning on doing more high speed races than Ultra4, we have several interesting ideas going into the build. One of which has to do with the brakes. Sure, the Spidertrax kits are light and will stop you.. but when it comes to the abuse that full time desert racing can dish out, I thought I'd put together something better. without spending $1000 per corner..

The new kit utilizes upgrades to OEM components, so while the kit comes with drilled/slotted/zinc plated rotors and Wilwood calipers, if things went south while away from home.. a simple trip to the parts house would get you back on the trail with a less blingy, but just as functional rotor and caliper. Even the brake pads are found at the local parts house. No exotic craziness that has to be ordered.

The design concept here has a few interesting points.

1st.. for an automotive based solid axle design, it's small, as in.. it's going to make a RZR look big. From our smallest Grunt chassis, it's 2" shorter from the rub rails to the roof and 7" less subframe hanging down from the rear engine design. The subframe is angled to drop lower in the front. This helps package the transfer case as well as helps front suspension geometry, and will allow it to still be a 2 seat chassis. It's possible to tuck it flat if your after a single seater, and it's possible to throw an IFS front end in there if your after the ultimate chase down..

2nd.. it's designed to go fast with lots of suspension travel, the rear able to swing over 20". By moving the pivot points higher on the front of the rear control arms the suspension naturally tries to follow the ground better instead of arcing forward as it travels up. Your looking at about 11" of uptravel from ride height to help chase these sxs down. The front is going to run a 14" shock on the axle with 8" up from ride height.

3rd... want to go slower? As in go Rock Crawling? With the additional room for uptravel comes the space needed to run portals. Set them up still having 4-5" of up travel and reap the benifits of clearance needed to keep up with Jesse Haines.. still maintain a passenger seat for a few trail rides on the off weekends.

4th.. still not convinced solid axles are what your after? Have a ton of money tied into your current side by side? Just stare at it a second.. with a slightly different subframe (or the stock sxs subframe for racing rules), I can easily throw all your current sxs suspension and motor in here... just sayin..

Got ideas? We do too.. What will we build for you?
