blatblat Posted December 14, 2014 Report Share Posted December 14, 2014 I'm trying to find 720 pics with 35, 36, 37+ inch tires with the IFS front suspension. And how it was done. No SAS please. Thankyou Quote Link to comment
datzenmike Posted December 14, 2014 Report Share Posted December 14, 2014 Then can't really be done. Twenty nine inch is understood to be about as big as you can go on a stock 4x4 without clearance issues. You would have to drop the front differential, torsion bars, sway bar, upper and lower control arms, tension rods about 8-9" from where they are and this doesn't even address the steering! Then the gearing. A quick check shows that to turn 37" tires you would need about a 5.8 front and rear differential. Sorry... SAS. Quote Link to comment
84720FourWheel Posted December 14, 2014 Report Share Posted December 14, 2014 The biggest I've seen on a "stock" 720 is 31s. I think that requires a body lift and torsion bar crank to not rub. Also, if you need tires that big, you need a solid axle. The CV shafts won't like the angle and extra force a big 35+ inch tire is going to put on it. Quote Link to comment
blatblat Posted December 14, 2014 Author Report Share Posted December 14, 2014 i know it would need to be lifted. Just trying to find more information. Pics=motivation. Quote Link to comment
bananahamuck Posted December 14, 2014 Report Share Posted December 14, 2014 This guy ,, he eventually went solid front axle ,, but there is some good reading if you wanna see a tall truck http://community.ratsun.net/topic/37709-82-720-kc-build-thread/ . Quote Link to comment
datzenmike Posted December 14, 2014 Report Share Posted December 14, 2014 A body lift would be so high it would look retarted seeing daylight between it and the frame. This is my 720 frame with SAS and 620 body. It's between 14 and 16" above stock height with 33 X 12.5s Quote Link to comment
blatblat Posted December 14, 2014 Author Report Share Posted December 14, 2014 hunted around and found two on a 720 site. Seems like this is the place to go this one went SAS and is now green Quote Link to comment
blatblat Posted December 14, 2014 Author Report Share Posted December 14, 2014 here is a video Nissan 720 in need of wheel spacers - YouTube Quote Link to comment
bananahamuck Posted December 14, 2014 Report Share Posted December 14, 2014 You keep using term SAS ,, do you mean Solid axle swap ? Quote Link to comment

Lockleaf Posted December 14, 2014 Report Share Posted December 14, 2014 A possible route you could try would be to cut the front section of frame off another 720 and weld that to the bottom of your existing frame. There would still be an ton of custom work to do with doing that, but it might provide you with a starting point. I would advise looking in to big lifts for tahoes to learn more about how they drop the suspension for an ifs. But like mike said, gearing will be a serious consideration, and 720s don't have the largest aftermarket. Quote Link to comment
poopypants720 Posted January 2, 2015 Report Share Posted January 2, 2015 I have Rancho shocks all around, 2"ball joint spacers on my upper a arms and 2" body lift... Even have deeper dish wheels to set out my tires from the frame a bit... With the closest corners in the rear of the front wheel wells hammered flat, I still barely rub when wheeling and am running 31"x10.5" toyo open country m/t tires... I admittedly don't have my torsion bars maxed out, buuut if I did, I'd lose ALL ride quality and lose the ability to effectively off road anyways... I was bending tie rods like crazy before I got ball joint spacers and backed off the torsion bars... I would have assuredly done more damage to steering parts had I kept on that way just for a little clearance... Forget going any bigger than 31 maaaaybe 32 on this ifs and even then, expect a little rubbing, a body lift, a little suspension lift and some wheel well cutting and/or hammering. Fwiw, I feel plenty confident with this much lift for moderate wheeling, had it out in the desert going over 1-2ft rocks, climbing in and out of washes and only felt minor rubbing... also gained a huge desire for power steering, LoL.

datzenmike Posted January 2, 2015 Report Share Posted January 2, 2015 The '81s at least had 4.375 axles but when Nissan went to the Z24 they dropped them to 4.11s. Combined with larger tires this kills the crawl speed. 1 Quote Link to comment
