My extended rear travel (and a few other things) - install story

So it was an epic 2 days at Performance Unlimited in Woodstock VT. I love this garage - and how I get to be wrench in hand the whole time :-)

First up was the replacement 4.56 geared third member from ECGS which happily came with marking grease from their final test


Nice coverage of the teeth - compare with old diff - had entire clean sections indicating lack of contact between ring and pinion gears...apparently is VERY difficult to correctly install gears, and best left to experts



All fixed- no more whining!!



Next we popped the MetalTech dual rate coils and Radflo 2.5 long travel shocks in place. Really had to squeeze to get those long shocks in


And 2 1/2" bumpstops


Also RED extended brake lines lol

Very happy with droop!



Then problem with adjustable Toytec RUCAs - not enough space without hitting the gas tank. At full (straight) droop OE sat a mere 1/4" above the tank! Is my tank different? Bought her totally stock, and no one else seems to have had this issue.



Many ideas kicked around - reshaping the tank, lowering it - too dangerous... put OE RUCAs back on and started front limit straps, welding plates and clevis mounts to the frame beside shock towers



Then retired to my hotel - almost 9 straight hrs of work...exhausting!



To be continued......with a surprise ending!

Interesting that the tank hits the upper ca.
Looking forward to seeing/reading the fix.

Re: My extended rear travel (and a few other things) - install story

I've got the identical rear setup, minus the brake lines... still working that issue out. You'll love it.

Curious to see if you get the same coil slap that I do.

Re: My extended rear travel (and a few other things) - install story

Next morning @bazross had suggested some cool Aussie offset RUCAs (Superior Engineering - made specifically for gas tank clearance lol) and was getting ready to order...



Then Rodney, the shop owner arrived, took one look at the problem and suggested a brilliant, simple fix, something he was currently using on his jeep ...



A limit strap on center of axle! At full STRAIGHT droop the ruca is at its closest to the tank but with articulation distance increases. A centered strap also does not inhibit articulation as it just pivots. So Rodney had his Jeep pulled in, harvested the strap and gave it to me - I was blown away!



A little cutting and welding and it was on, performing exactly as hoped :-) So my red RUCAs went in and just barely kiss the tank but all ok







But noticed the different angles they sit at and it's clear my track bar is too short - it's pulling everything to the side. Got a Rokman adjustable - thanks @svoruz !

On to the next part!

Re: My extended rear travel (and a few other things) - install story

I had RUCA but took them out and put the originals back in. They are a pain in the A** to grease ( gas tank side is impossible to do ), i never heard of anyone bending those, and it was always seizing because of our nice northern climat and roads , love Johnny joints...( changed it 2 times ) I also have that drop difference on the passenger side, on a lift the passenger side drops about 5 inchs more, i just live with it. Check how your rear bump stops hit, mine don't really do anything and i have to figure out why, they are installed properly but i end up stuffing my rear wheels so much in, that it jams, maybe my wheels are too big ? Nah... lol

You mean yours hit the gas tank too?

Haven't heard slaps but then I'm taking it easy while new gears are getting broken in lol

Re: My extended rear travel (and a few other things) - install story

Looks good debFJVT!

I am curious to get your thoughts on the Radflo 2.5's in the rear. They are a great performance shock to compliment the removal of the sway bar but I feel mine are slightly "clunky". Please share your thoughts as you break them in. Also, did you talk to MT about those 2.5" bump stops? I have the 3" with my kit and both the shock and bump pad bottom out at the exact same time. I feel like the extra 0.5" up travel might harm the shock... just an observation.

Re: My extended rear travel (and a few other things) - install story

Mine touch the tank, and I've just lived with it as there seem to be no detrimental effects (as of yet). But I am considering those offset uppers you posted. Seems like a viable option, but I need to justify the expense, not sure its an issue worth solving yet.

See here (What did you do TO your FJ Cruiser TODAY?) for the discussion we had on the coil slap.
