Rate increases for different bars over the stock 20.7mm 521 torsion bar
 
620 to 7/77 - 21.9mm, 126% stiffer
620 from 8/77 - 22.0mm, 128% stiffer
720 2wd 10/81 to 12/82 - 24.0mm, 181% stiffer
720 (all others) - 22.0mm, 128% stiffer
Nissan Comp - 26.0mm, 250% stiffer

  

OK I've done some research. My 98-99 Nissan Motorsports catalog provides some data on truck torsion bars.
 
All 521/620 torsion bars are listed under the same P/N's
99996-T4010 for their oversize 26m bar
99996-T1450 is their 2 stage bar
 
The same part numbers are listed under the 2wd 720. The 26mm bar is also lists for 4x4 720 up to 12/82.
 
They also provide the stock bar diameters as follows.
 
521 - 20.7mm
620 to 7/77 - 21.9mm
620 from 8/77 - 22.0mm
720 2wd 10/81 to 12/82 - 24.0mm
720 (all others) - 22.0mm



WOW, Dime Dave great info! I just got flamed a little for asking about the torsion situation on the 620 boards. They linked me to this. I ordered the T4010 for my '73 620. It's great to know that if they are too stiff I have cheap options at the wrecking yard that'll get me stiffer but under the 26mm size.

Much appreciated info!

Talked to NissanParts.cc today and they have informed me that the M-99996-T4010 is NLA

 

I asked Russell, the internet salesman, to look into the M-99996-T1450 bar for me.  He is calling Nissan and maybe Sway-A-Way directly.

I also emailed Sway A Way and asked if they could still produce parts or a kit for the T1450 (SAW part/kit 1440 i think?)

 

Waiting for replies from both with my fingers crossed.

 

If I get negatives on both of those I guess I'm going to start my search for 2WD 720s built from Oct '81 to Dec '82 and grab their 24mm bars.  They will be a vast improvement over my 620s wimpy 21.9 bars at least.   I get to the bump stop much too quickly for comfort right now.

 

I actually have doubts about the HD bars being great for lowered trucks.  I'd probably need to set it up so that the adjusters were already locked out or close to it to get what I'm looking for.

hit the link to his build in his signature... page 3 is where he got them shipped to him, and he installed them later on...

Next big project. Finishing up the rear and then moving up front when I get everything assembled. Soon.

Bumping this thread because I am currently looking at the NISMO inventory sheet (work) and came across this number on a browse. 

NISMO shows the 99996-T1450 620 torsion bar set is still in stock, but most likely out of production. They appear to have a few sets on the shelf. If anyone reading this is interested, PM me for pricing. I won't post that publicly. 

They have a few more NISMO HD Torsion Bar PN's listed that I'm going through today for more fitment or information.


...seems to me we are being held hostage by these candy-ass pussy, limp wrist, hanky twisting, girly-man, cry when Forrest Gump's mom died, crystal gazing, Om chanting, sandal wearing, whiny voiced, oh I broke a nail, fucks.
