What Our Customers Are Saying About Our Spring Smashers

One of the biggest things that the ultra force has done for my program is it helps me to make a much more calculated bump stop change by being able to overlay the graphs which, in turn, saves me a ton of track time.

Also, the overall speed of the machine by being able to punch my center to center measurements in and let the machine run through my full travel all by itself in a matter of seconds it’s literally cut my time of setting bump stops in half.

Another nice feature is being able to store all the data instead of having stacks of binders I can just go back in the file and it shows me every piece of information as far as travel and bump loads from earlier races in the season.

Since buying this Ultra Force machine we have gotten more precise numbers on our bump stops and load numbers. This machine has made it a lot easier to scale and setup times have been decreased compared to traditional methods due to being more accurate! The ultraforce is an awesome machine and much safer compared to other spring unloaders. I highly recommend this product!

The Wehrs Ultra Force Machine is extremely user-friendly it has all the tools within the software to do virtually any type of test you’ll ever need when it comes to spring smashing, pull bar rating, and bump stop tuning. Not to mention it follows suit with all Wehrs products and has the nicest machined pieces and is a well built and engineered machine

The Wehrs Machine 4 Link Software is an awesome tool when it comes to comparing different 4 Link arrangements there is nothing sweeter than being able to put in data points from the comfort of your office chair to see what changes made and how they affect the suspension through travel vs. having to move stuff around manually and using a tape measure

Thanks to the new Ultra-Force 4-Link Simulation software we can now more accurately and timely simulate different scenarios in the rear suspension for our customers. Which in turn has allowed more valuable information to be exposed to us here at GRT Race Cars and to be expressed to our customers. It has relatively taken the guess work and variables out of determining steer change, center to center change and many other measurements. Thanks to Chad Wehrs, Ultra Force and all other participating parties!

The ultra force is easily the best suspension machine on the market. I have used many different machines and the ultra force allows me to make faster and more accurate changes to the cars I work on. If you don’t have an ultra force machine, you are behind.

The new Auto Ultra force machine has given me transparency to hidden data within my setup.  The technology of the machine has given me the tools to make improvements to the balance of my setup and the speed of the machine has given me the agility to make those improvements in a hurry.

Great Work on this program Wehrs Machine, after inputting my chassis locations it has given me great tuning options on what to adjust other than moving the links from hole to hole. 

Great Work Wehrs Machine well done!!

The Ultra Force Machine is definitely the best load machine in the business. I’ve worked with competitor’s products and the Ultra Force is a step above. Its easy to use interface along with the time it saves on set-up and at the racetrack is unparalleled. I would recommend the Ultra Force to Anyone who is looking for a load machine without a doubt.
