Esteban Posted October 7, 2013 Report Share Posted October 7, 2013 Do they make drop spindles? I want to go more then 2 inch! 1 Quote Link to comment
wayno Posted October 7, 2013 Report Share Posted October 7, 2013 No, there is no drop spindle for a kingpin frontend. This is the only thing made for the 320/520/521/early 620 when going this route. https://www.google.com/url?q=http://community.ratsun.net/topic/43421-320-zd-lower-control-arm-2-drop-250-shipping/&sa=U&ei=_i9SUpWAH8qArAHUqYD4AQ&ved=0CAcQFjAA&client=internal-uds-cse&usg=AFQjCNHxKAjVJotjhVbatiySAcvU_WNZ7A There is also this route, which is way more involved. https://www.google.com/url?q=http://community.ratsun.net/topic/34698-320-balljoint-conversion/&sa=U&ei=ajBSUrDsMqKGyAHI2ICIDQ&ved=0CAcQFjAA&client=internal-uds-cse&usg=AFQjCNGO33wY_lKekhFjpA30M6fE7LAqow Quote Link to comment
thisismatt Posted October 7, 2013 Report Share Posted October 7, 2013 For a king pin 521, no. For a 720 or hardbody (d21), then yes. But you will need to piece together parts from a 720 or 620 with balljoint arms and use custom or modified upper arms. Quote Link to comment
flatcat19 Posted October 7, 2013 Report Share Posted October 7, 2013 Index them bars. You can get more than 2" but will sacrifice ride quality. Quote Link to comment
datzenmike Posted October 7, 2013 Report Share Posted October 7, 2013 The above but replace the front shocks to firm up the suspension. Lowering risks bottoming out the exhaust pipe and 40 year old shocks won't help. For the back a 2" (maybe 3 ") set of blocks between the leaf springs and the axle. Lowering blocks usually come as a 'kt' with longer U bolts too. Quote Link to comment
Esteban Posted October 14, 2013 Author Report Share Posted October 14, 2013 I understand the lowering blocks. But what you mean by index? Quote Link to comment
wayno Posted October 14, 2013 Report Share Posted October 14, 2013 I understand the lowering blocks. But what you mean by index? The front torsion bars are connected to the rear side of the lower control arm(LCA) on each side, you can loosen the torsion bars, then back them out and re-index them so when you tighten them up to the position that they were before, but the truck will not be as high in the front when done. There are draw backs to doing this, if you go to far down, it will bottom out on the bump stops, or when you hit a bump it will bottom out, some that want to be real low will trim the bump stops, others will remove them all together, but if you hit to big a bump, it will hit metal to metal, it does not lead to a good ride.

glorydime Posted October 24, 2013 Report Share Posted October 24, 2013 For firming up the front, I'm seeing some difference opinion. I mainly want to know if y'all think stock shocks are the best route or going with a firmer kyb after market shock is best. I reindexed my bars and put in blocks in the back. I need new shocks either way, just wanted some opinions. Quote Link to comment
datzenmike Posted October 25, 2013 Report Share Posted October 25, 2013 OK you are lower to the ground... lower and closer to objects that could rip your exhaust off or puncture your oil pan. It would be best to have stiffer springs that don't allow as much movement when going through dips in the road. Likewise you don't want to go over a speed bump (even slowly) only to slam down on the other side and bottom out. A shock absorber doesn't limit travel but it resists change, especially sudden change. 1 Quote Link to comment
flatcat19 Posted October 25, 2013 Report Share Posted October 25, 2013 Yes. Firmer shocks. KYB Gas-A-Justs are money. Don't buy GR-2s or Excel. Just because it says KYB doesn't mean much. The lower end of the line is softer than stock OE replacement crap. Spend the money. Quote Link to comment
glorydime Posted October 25, 2013 Report Share Posted October 25, 2013 Thanks guys Ill go with the kyb gas adjust, I was looking at them. I had seen so many peeps chatting about the shorter shocks but not really firmer one. Thanks again, Ill order them soon. Quote Link to comment
mrbigtanker Posted October 25, 2013 Report Share Posted October 25, 2013 Hold on not sol fast listen to what these guys said,good shocks are good shocks,here is your problem finding a good shock short enough.Firmer is no problem you can spend 1000.00 on the best shocks your still going to bottom out,if you have fab skills or a high limit credit card look in to going a different route because reindexing works but its the cheap way and you are going to bottom out no matter what you do.I went to coil overs and the ride is better then torsion bars but the geometry of the coilovers dont work for the right drop and bottoming out,it ends up being a mini truck ride again.Hope this helps.

flatcat19 Posted October 25, 2013 Report Share Posted October 25, 2013 Pinto shocks up front. 620 shocks in the rear. You could contact a member named Beebani and ask him out the extended shock mounts he makes/sells. 1 Quote Link to comment
izzo Posted October 25, 2013 Report Share Posted October 25, 2013 just cut the torsion bars with a sawzall. It'll slam itself out. 1 Quote Link to comment
flatcat19 Posted October 25, 2013 Report Share Posted October 25, 2013 just cut the torsion bars with a sawzall. It'll slam itself out. Monkey's mysteriously fell out of his truck. Much like the wheel of his 210. Both pure success for instant low. 2 Quote Link to comment
glorydime Posted October 25, 2013 Report Share Posted October 25, 2013 So I didn't slam my truck. I went one spline and adjusted the bolt and she went down two and have, three inches. That being said I'm thinking the gas adjust would be the cheapest firmest route? I'm no rich man! 1 Quote Link to comment
flatcat19 Posted October 25, 2013 Report Share Posted October 25, 2013 Yes. You will not be disappointed. 1 Quote Link to comment
Zonargx Posted March 30, 2021 Report Share Posted March 30, 2021 How low does one spline get you? I’m trying to lower my 521 in the front just about 2 inches. To lower you go clock wise or counter? 1 Quote Link to comment

To lower you go clock wise or counter? So good question, 1 spline movement only, should do the trick for your desired drop. Turn the drivers side counter clock wise and the passenger side clock wise. That will move them both in the direction need. When you lie down under the truck it will make sense. Looking forward and you will be like holy shit.lol 1 Quote Link to comment
banzai510(hainz) Posted March 30, 2021 Report Share Posted March 30, 2021 (edited) I would try to just turn the torsion bolt all the way out first and see where that puts you first and its the EZist thing to do. than pull the torsion bar out first. I think I almost got 3in in front just by turing the square nut out Edited March 30, 2021 by banzai510(hainz) 1 Quote Link to comment
Charlie69 Posted March 30, 2021 Report Share Posted March 30, 2021 Turning the torsion bar adjusting bolt out removes the tension on the torsion bar and results in lowering the front of the truck. This also removes the weight bearing and spring action of the torsion bar transferring these qualities to the shock absorber. In essence you will end up blowing out your shocks. 1 Quote Link to comment
banzai510(hainz) Posted March 30, 2021 Report Share Posted March 30, 2021 Charlie I dont think that is totally true. the torsion bar is still smae stiffness no matter what position it is. I think hell be fine I have KYB Gas a Just and they still good 12yrs later as I went to put soem cheap NAPA gas shocks in and the KYBs where still harder than the new Napa branded ones 2 Quote Link to comment
Charlie69 Posted March 30, 2021 Report Share Posted March 30, 2021 When you tighten the torsion bar adjusting bolt you are twisting (loading) the torsion bar. When you loosen the torsion bar adjusting bolt you are un-twisting (un-loading). When you tighten a torsion bar up to lift the truck you are alsomiking the front suspension stiffer, harsher ride. This is what a torsion bar is designed to do set the ride height and the stiffness of the suspension (support the weight of the front of the truck, cushion bumps) . Quote Link to comment
banzai510(hainz) Posted March 30, 2021 Report Share Posted March 30, 2021 your just rotating the bar so the A arm moves up at the other end moving the A arm one spline makes the A arm move to a lower position but the stiffness is the same. Kinda like Lowering spindals the axle bearing shaft is just moved up but the spring still is the same . Thats how I think of it. 2 Quote Link to comment
Zonargx Posted March 31, 2021 Report Share Posted March 31, 2021 Thanks guys I just lowered myself truck to my desired preference 1 Quote Link to comment
