Cyclone 300C Suspension Upgrade

The parts have been acquired....



Now the work begins!

Stay tuned.....

OK I have to ask what are the 2 springs leafs for.

I'm going to add a leaf to each pack to increase rate slightly.

When loaded, the leafs are starting to bent negative and it is my opinion that you don't run 3500# springs on an axle that rarely weighs under 6900#.

At the shop now trying to get motivated....

There was enough clearance to mount the shocks outboard. This is always preferred as it gives them more leverage to control sway and wheel hop. I wanted to use a heavier valved shock like the 6400 series RV KYB since they are setup for a 5k+ lb axle weight, but I was afraid it would break the cheasy I-beam frame rail it was hooked to......

Cutting, drilling and arching the material to match the OE main leafs. One more leaf should give me an extra 1k lb. capacity per spring. Obviously, I wouldn't use this capacity as it's just there for stabilty:




The pivot bushings in the Dexter EZ Flexes are dusted after 6 months/4-5K miles....gonna have to call them Monday...


Dropped lower shock mounts from Rubicon Express:


After mockup and welded up:


Angle iron upper brackets welded on:


View from under:


With the tires back on. Looks like a pro did it.....:


All finished....ended up with 5/8" lift and more stability. Can't wait to load it up and see how nice it rides.


Bonus project....Battery mount and dedicated AGM battery under the the garage for devices that get run back there. It will serve to keep toy batteries charged off solar, run my HAM radios, and future dedicated garage/outdoor entertainment system without the need for 4 ga. wire run to the rear:


Long day, but should be worth it!

Nice job! Wana do mine now (g)

What signs were the ez flex showing to think they are tost?

Good job, I see I need a welder now.

Thanks! I try to do things as clean as possible....

The EZ Flex has 1/8"+ of movement in the rocker pivot bushing. They had grease in them, they were just all wallowed out.

Nicely done
