Hi All

I wanted to share my custom suspension setup for those of you, who like me, may be running a extra heavy O8S and are looking to improve things for high jump landings. I have a bashplate installed, Pro-line MX43 badlands wheels and tires and the Mamba Monster 2028 1100KV - all of which add allot of wheight to my truck. With batteries it now weighs 15.5KG (34.2lbs)!

Firstly I bought a set of shocks from the Kraton 8s EXB with the thicker and stronger shock arms. The stock shock springs that come with these are rated with a spring rate of 2.21N/mm (12.62lb/in). I tried running them on my rig but I still found landings from high jumps felt very hard and the truck was bottoming out and I was breaking stuff. Next step, I did a ton of reading online and found a place that had a set of springs that I was hoping would work. They are nearly the exact same size as the original springs but have a spring rate of 4.2N/mm (24.00lb/in). I received them yesterday and am happy to report that they fit like a glove on the EXB shocks. I took the truck out and did several high jumps at speed today and I am very happy with the results. My truck feels allot lighter on its feet and landings are MUCH softer and more controlled. High speed cornering seems unaffected and I had no rollovers at all. Best of all my a-arms and turn buckels stayed in tact and I dare to say I think this upgrade is going to help me save allot on parts that will hopefully last much longer.

I am no expert but I highly recommend to try this setup guys. The only negative thing I have found thus far is that the front end tends to lift a bit more under heavy acceleration, but I don’t mind this as a trade off for the increased suspension give.

I am attaching some pictures of my setup here.

cheers!

I wonder if they are the vg racing springs available on eBay?
 
Also curious about this and wonder how they would work or if shorter options are available for the Kraton 8s (the shorter front springs).
