Question only for those who have replaced their leaf springs

I posted something related earlier, but now I want to hear from those who have replaced their leaf springs with brand new ones from Moss. Specifically what was the difference in height if any.

No change in height for me, at least not noticeable. Ride certainly improved. I had hoped it might correct the lower left side syndrome, but it's still a bit lower on the left. Not sorry, I also installed gas shocks at same time.

Starting earlier this year Moss stopped carrying the springs they have been carrying, and now have springs made by Heritage, because the old ones were of, shall we say, questionable quality. I don't think there have been enough people use the new ones to yet get a whole lot of response about the new ones, plus only time will tell how well they hold up (the old ones tended to sag after a few years, ask me how I know, I just sent some original ones out to be re-arched to replace the repacement ones that get lower every year)

I helped install a set ofthe new springs right after they came available. The car they'r eon is very much level now, rides at the stock height, and I don't forsee any issue swith them, versus the "other" springs Moss used to carry.

The Heritage springs are on the blue car pictured. It no longer scrubs the tires with two people in it and cornering. The ride height was raised to original spec.

I don't know if I installed the new springs or just a better pair of the old ones. Mine new leaf springs were put on about a year ago . . .? The old ones were pretty sagged out, and it had uneven height on both sides. The first set Moss sent me were just absolutely crappy. After installation, the car was still uneven and looked terrible. I had to remove them (ugh) and Moss agreed to send me another better pair (no charge) which solved the problem. I hope the newer pair was the better "Heritage" quality mentioned above. I never bothered to check when they were new, and I have no idea how I'd check now. But they acknowledge that they'd been unhappy with the quality of the springs. Which did make me wonder why they even bothered to send me the crappy ones in the first place? But, anyway, the car sits right, as far as I can tell, though maybe I should go out there and measure just to be sure.

One thing I do want to point out. I replaced my springs several years ago with springs I had bought several years before that - genuine British Spring springs - the real McCoy (they were the original manufacturers of MGB springs). And - they were still about 1/2" high for the first year.

My point is that, although the quality has varied over time and manufacturer, I'm not even sure that OEM springs were perfect every time. Maybe even they had to settle in a bit.

I replaced the leaf springs on my B about a year ago. I don't know if I got the new ones or the old ones. The handling was GREATLY impoved. It sat about an inch high at first but it has settled nicely. ( I kept 2, 80 lb. bags of concrete mix in the trunk over last winter)

Dakine,
I replaced mine 3 years ago to alleviate the dreaded "bachelor lean" to the driver's side. Height is right in the range of factory spec and still sits level. While I had them off I replaced gas tank as well, but that was to protect a newly overhauled engine...

About two years ago? My car has them and has been done for about 2 years.

Are the Heritage springs Moss carries available for the GT as well?

Some of you may recall that I was complaining that when I changed my rear springs, it moved the axle to the left about 3/4-1inch. This caused my left tire to rub excessively. I had purchased these springs from Brittek about 3 years ago. I finally installed them about 10 months ago and that is when the trouble started.

After reading here about better Heritage springs, I decided to buy them. The new springs have the same Moss sticker and part number as the springs I bought from Brittek. I wish I had taken a picture of the difference in these springs. Side by side with my old original springs, the new Moss springs and the Brittek/Moss springs, there was at least an inch difference in the height of the arc. The Brittek/Moss were arc'd the most. My original springs were just slightly less arc'd than the new Moss springs. When I installed the new springs, the rear end moved back to centered. No more rubbing.

I cannot understand how the Brittek spring could have been arc'd so much more! They were a bear to install too, the eyes being closer. I still have the originals and the Brittek springs, I may still post a photo.

HOw would the springs affect the centering by an 1"??

Good question, Chris! My question would be; why are springs from the same distributor, with the same part number, be so different?

Mike

I had a new Moss set and they would not fit. They were too sprung - sounds like the small print on a bottle of viagra. I had to take them to a spring shop and have them de-arched so that they would fit.

The old springs were twisted. If you sat the eyes on the floor and put a level on the perch area (at the top), it was angled a few degrees. Bothsprings were twisted toward the driver's side of the car, lending to the off-center axle issue. Switching the springs from one side of the car to the other may have helped the bachelor lean, but since they were both twisted the same way, the axle still pushed left. It was a jig issue that's now fixed with a (new?) Heritage jig.

Because the application didn't change, only the vendor.

Jeff,

That had to be the case, I did switch the springs to no effect. New Moss springs are perfect. What was odd, is that the old springs appeared to be better made.
