I've read some of the forums and there's very little about stock height spring sets available. I want the stock HD (heavy duty) springs

From memory, the Volvo 240 may be fitted from the factory with one of three spring sets by rating as follows:
1. Light Duty (LD - not seen these)
2. Medium Duty (MD - Typical on most NA 200s save for Diesels, GTs, and Turbos)
3. Heavy Duty (HD) I've only seen Scantech sell what are called HD springs.

The difference is the wire diameter. The factory specification is out there on the i-net. I've seen it before but am not sure. Could not find it. Maybe turbobricks?

All of my three 240 sedans came with the medium duty springs.

The 242 GT was a rally suspension setup (I had a '79 grey market from Holland):
1. HD springs front
2. MD springs rear
It becomes a rally suspension with the 22 or later, the 23mm (I have one!) rear stabilizer bar and the front 21 mm stabilizer bar.

The 200 turbo
1. HD springs front
2. MD springs rear
It is a street setup with the 23mm stabilizer bar in front and a 21 mm stabilizer bar in the rear.

I won't address the varieties of set ups with the Diesel 240 offering.

SO, just like my 1990 240 DL (N. American market) with the dual-floor-pan design, it comes with stock HD springs. I can load hundreds of pounds in the rear with NO sag. It is a wholly stock Volvo 245 DL (a li'l red kumba!) WITH the locking rear differential.

The anecdotal information indicates Scantech is a brand best to avoid. Is Scantech the only manufacturer of Volvo 200 HD springs? I guess a call to the local Spokane Volvo dealership is in order?

When building the suspension on my 1992 240 GL (moon roof, m47II), I want to install NEW HD springs.

No, no lowering ANYTHING. You cannot use any spring lowering kit on any Volvo 240 without using a variable position panhard rod to center the drive shaft after lowering the suspension, even though it seems to motor okay. Also, you may have to use different-length idler arms on the lowered suspension. Else, you run the risk of premature mineshaft U-joint failure.

Any suggestions?

Thanks.

Just and FYI the 240 front springs changed in 90-91 from the softer 13.4mm to the 13.8/9 mm on all fitments, wagon or sedan, the same as early turbo's.
The 14.2 mm are in fact the GT size and available from B&G/Leijsfors of Germany. I have had a set of the GT springs on my '91 245 for 7 yrs and 150k miles, very good spring, probably teh same as sold by ScanTech.

If you put in stiffer front springs be forewarned that if you leave the rear stock, especially the earlier stock size, and use stock shocks you will be setting up the car for a roll-over, as the rearward pitch of weight into a corner will cause the back to dive and front will not - flip!
If you change the front's to GT, at least put in overloads, later wagon springs, and/or high pressure gas shocks
It is far better and safer to add stiffness to the rear springs with gas shocks, and keep the front struts ydraulic and a modest increase in spring stiffness to keep a good ride. Sitfining the front springs doens't help with load carrying ability very much.
Oh and about rear axle centering, if you put the GT/Overlaods on with Bilstein HD shocks and struts like I have, the ride height increased 1/2" to about 11 1/2" overall. The small increase in ride height is still enough to re-center the rear axle with the adjustable panhard bar. I have the IPD panhard bar, and although the adjustment amount was small, like 3/32", the biggest difference it makes is the much bigger poly bushings on the adj bar keeps the rear end planted in corners much better than the stock panhard bar, FWIW, a better set-up.

Just put on IPD HD's on the rear and they're pretty good. With a full load the rear hardly drops down at all. But when there's nothing in the car except 1 or 2 people, the rear "jumps" around when you hit bumps. Kinda skips. Not too terrible, but that and the slightly harsher ride is interesting. Unsure how it will fare in winter time, but hopefully not too bad. It's a trade off for sure. But if you tend to haul, go for it. If you really don't, then pass.
Some people mistake bad TABs for bad springs... We had it in our mind both were bad. So, we replaced them both at the same time... TABs and HDs... Upon closer inspection when we got them off, the stock springs were fine. Ah well

Just a couple of comments, and without reading all the posts. 240 turbo springs are nothing special, same as non-turbo. You recognize the 79 GT R-sport springs are the ones to find. You can use wagon rear springs in a sedan. You can set wagon overload springs made by Volvo. I recall Diesel or 6 cyl springs might be fitted to a regular 240 for whatever reason. Good luck.

You said almost the exact same thing three years ago.

My thicker-than-GT Scantech springs are still going fine, FWIW.

Yeah, the ScanTech steel springs seem to be one of the few quality products they sell.

Maybe some real Swedish steel in those ScanTech springs for your rolling Volvo Swedish Iron 240.

Got no kitty for the grey Volvo.

Sounds like you might just want to go with GT springs(stock height) in the front and stick with the stock springs in the rear. I think you'll find that not all 240's are "dialed" in straight with a stock height spring and stock panhard. I set my IPD adjustable to stock length and found it to be centered with B&G's. Personnaly I think the progressive rear springs are a nice improvement over the linear rear HD 245 ones which ride like an unloaded truck. I have 3 months on B&G lowering springs and actually like them just fine. My original feeling was that I wasn't going to. Someday I would like to try GT's in the front and stock in the rear on a sedan. Remember its tough to go really stiff with a solid axle without impacting ride comfort.

Don't forget you have the front and rear stabilizer bars that also effect the under to over steer balance.

If you go to hard with hard springs and stabilizer bars, yet have somewhat under-steer to neutral, and maybe over-steer (back end wants to slide out), you may need stickier tires.

Don't got no kitties.

Not for years for a Volvo 240.

According to a post from Turbobricks that I reference often:

Spring thickness according to VADIS
Front:
1229337 14.2mm
1229338 13.5mm
1229339 13.3mm
1229137 13.85mm/13,9mm
1205951 14.8mm
1330841 13.5mm
Rear:
1212426 12.0mm 244GL, 244GLE,242/244GLT,265GL,264,262C
1212427 12.7mm 245DL,GL,D
1229052 12.95mm 245/265GL,DL,GLE
1206750 13.8mm 245DL Australia

The Scantech fronts that FCP sells have a 14.5mm wire diameter - as you can see, they are thicker than any front spring ever offered on a 240 but one. I believe the 14.2mm spring was the diesel spring, I seem to remeber hearing that the 14.8mm spring was an extremely rare performance option.

Not that anyone asked, but......1229337-9 is the part number for the R sport front spring on the 79 GT (and rarely on the 78). It is the only spring of note I have ever seen on a gasoline powered 240 sedan. Turbos have standard springs within my measurement capabilities. Wagon rear, overload and diesel springs excepted from the foregoing comments.

I bought the HD Springs from IPD 150K miles ago. I like them. Four adults and luggage in the car and it sits nice. 1 driver and it is not harsh at all.

Scan Tech doesn't manufacture anything, they buy stuff and put their name on it. They get a deservedly bad rap for rubber products and maybe wiring but some of their items are OK. I suspect the overload or replacement springs are fine.
I have used wagon rear springs on sedans to get allow a little more trunk capacity. Dan

I tow a beach cat with my car so I replaced the stock rear springs on 1987 240 DL with IPD's offer of HD springs, with Boge Turbo shocks. The rear sag disappeared and I can load it up now. Stiffer ride on the bumps for sure, also some clanking noise occasionally on the bumps, as if a spring reverbrating. But very good road control, settles really well after the bumps. With the trunk full and/or with the trailer hitched the car rides sweet, though.

I used Moog Cargo Coils in the back of my 245 Diesel. They were about $60 at NAPA

I am adding 450 lbs of battery to my 240 Wagon behind the rear axle. Those look like a good option.

Are you doing an electric power EV Volvo 240?

Why 450 pounds o' battery.

Be careful. Best to place such mass and weight low and in between axle if you can.

I love kitties! So long as they are taxoplasmosis-free. Hah!

"I am adding 450 lbs of battery to my 240 Wagon behind the rear axle." Holy pendulum Batman! No way you can move any of it in front of the axle? That being said, this is less of an issue the lower you mount it and the less you drive in slippery situations.

I am still working out the location of all the components of this electric
conversion. The battery pack will fit so neatly as a block under the
plywood cargo deck. It is tempting to just pack it all there,

All that weigh back there is a consideration though, the DC motor wont
provide engine brake like internal combustion. I may be putting a third to
half of the battery up front, with the motor that would be about the weight
of the old B230.

I'll second the Moog Cargo Coils. Mine have been an huge improvement over the originals in my 244. I can measure their coil diameter if you would like to know what they are?

The Scantech springs are good, I have used them for months now, and a few others (on Turbobricks.com) have been using them for much longer with no complaints. Stock height - well, maybe .5"-1" taller - and comfortably stiffer than stock springs. Good match for a Sachs gas shock, perfect for a mildly stiffened, good-handling 240 that doesn't shake your teeth.

Scantech's bad reputation (deserved!) is because of their plastic/rubber items, which suck mightily.
