GOLSETH Posted June 7, 2011 Report Share Posted June 7, 2011 Ok, so my 73 620 is on 3" blocks in the back and the front torsion bar anchor bolts are as low as I can get them. How do I go a little lower SAFELY in the back? I've heard if you go with 4 inch blocks it trashes the carrier bearing and if I take one of the leafs out it will be too soft. I've also heard someone say 720 leaf springs will lower it but I can't seem to find any. Any input would be greatly appreciated. Thanks! Quote Link to comment
metalmonkey47 Posted June 7, 2011 Report Share Posted June 7, 2011 Fist of all, I LOVE your truck and LOVE the color on it! Second, why lower it? The stance is perfect! Quote Link to comment
SoCaLKiDz Posted June 7, 2011 Report Share Posted June 7, 2011 YUMMMMM JDM front end..... However i was told the same and there is a set out in my junk yard.. I can swing by and see how much they are. Quote Link to comment
yello620 Posted June 7, 2011 Report Share Posted June 7, 2011 It is 720 4x4 rear springs that are supposed to work, i think they were worth two inches of drop. Quote Link to comment
Farmer Joe Posted June 7, 2011 Report Share Posted June 7, 2011 well in your case from the big tire you have, your gonna prolly be better off to have the stock leafs de-arched by a shop... this will keep alot of the axle wrap out of the picture, and youll still have all your leafs to carry a couch or something, if needed.. you can take a leaf out right now, and then flip it and put it back in the pack... it should stiffen up the pack, and maybe get ya an inch er two closer to the ground... and then you can also do the 4x4 720 leafs... chester on here has a set in his 620... lowered the truck about 1.5in... food for thought...

Wide14u Posted June 7, 2011 Report Share Posted June 7, 2011 you could use sand bags to lower it lol Quote Link to comment
albyneau Posted June 7, 2011 Report Share Posted June 7, 2011 you could use sand bags to lower it lol Don't laugh~ sandbags have their place! A friend and I both had big block '68 Camaros, and between us we carried four 100# cement bags for traction.... Quote Link to comment

And its hard to tell from the pics but the rear is a little higher than the front so the whole truck leans forward and Im not a fan of this look. Im going for the even stance not the hot rod look. YUMMMMM JDM front end..... However i was told the same and there is a set out in my junk yard.. I can swing by and see how much they are. You can but youre in arizona and I dont think shipping leaf springs would be very pracitcal, probably not worth the $$$ and just for you! well in your case from the big tire you have, your gonna prolly be better off to have the stock leafs de-arched by a shop... ...you can take a leaf out right now, and then flip it and put it back in the pack... it should stiffen up the pack, and maybe get ya an inch er two closer to the ground... Im sorry, do you mean i should just take a leaf out and roll with it? How much do shops normally charge for this to "de-arch" leafsprings? What type of shops do this? Thanks for all the replies guys!

flatcat19 Posted June 7, 2011 Report Share Posted June 7, 2011 You can use pinion shims to save your carrier bearing. Not a fix-all, but it helps. 2 degree shims can be bought at almost any parts house. There is always the option of coilovers and a tri 4-link. Quote Link to comment
GOLSETH Posted June 7, 2011 Author Report Share Posted June 7, 2011 Thanks for your input but I'm kinda looking for a "quick" and "cheap" way to lower it just for the next few months. I'm leaving for Japan in September and I'll be there for 2 years so my Datsun is going to a good friends place in Mississippi and getting c-notched, body dropped and bagged while I'm in the land of the Rising Sun!

Could always raise the front an inch.... :huh: Quote Link to comment
GOLSETH Posted June 7, 2011 Author Report Share Posted June 7, 2011 Could always raise the front an inch.... :huh: haha figured someone would say that... unfortunately once something is set at a height it can only get lower in my opinion... id never raise anything back up haha... hence why its getting bagged... then i wont be able to get any lower hahahaha Quote Link to comment

But, if you must have it lower, and it is in fact only temporary, get some 4" blocks, shims, slam it and rock it. OR, get off the pot. Quote Link to comment
chester Posted June 28, 2011 Report Share Posted June 28, 2011 With my truck I have the 4x4 720 leafs and at first I had them with _ inch blocks and the front all the way down and when I hit bumps the rear end woukd hit the frame I had about 2 inches of room back there now I am running only 2 inch blockd anf dont have to worry unless I am loaded down. Also the 4x4 720 leafs feel a lot soft then stock 620 ones Quote Link to comment

Why bother with that if you're leaving and it's going to change anyway? Quote Link to comment

]2eDeYe Posted June 28, 2011 Report Share Posted June 28, 2011 With the 4 inch blocks, you just need to make a 1" or so spacer for the carrier bearing to keep it from getting torn up and to minimize and u-joint vibrations. Quote Link to comment
