Howdy,

Anybody know the spring rate for the stock rear leaf springs on a Ty? I've tried searching (both here and at other sites), but can't find that info.

Thanks,
Bill

I believe the stock rate for a typhoon is 225, I have been trying to make sure that is correct and havent found anything to say otherwise. Also i think the stock rate for a syclone is a bit lower.

Bump. Anyone else have any leads/info?

The only reason I ask is I called BellTech about their #5954 lowering leaf springs (the ones recommended on Jas' web site). They say their springs are 20% lower rate than the stockers. After pressing them for an actual number, I was finally told their springs are 130 lb/in rate. If you believe their "20% lower" statement, that would put the stockers at 162 lb/in.

Of course, they could be talking about non-Ty stock springs. After all, they recommend the same spring for all S-10 pickups and blazers/jimmies from '91-'93 (the SyTy years).

I want to put lowering springs on my Ty, but don't want to drop too much from the stock rate -- going from 225 to 130 is a 42% drop. Maybe I'll just have the stockers de-arched....

Anyone know of any steel lowering springs with a 200-220 lb/in rate?

The Bell Tech drop leafs lowered my truck a little under 2".
I also added a 1" pinion correct block to get just under 3" of total drop.

No one at Bell tech could tell me the spring rate either and when I asked why they recommended the same springs for a pick up as the sport ute they had no explanation.

Obviously these springs were not designed with a required curb weight in mind.

With the lack of spring options I just did it anyway and am VERY happy with them.
The spring rate feels stiffer than the flex a forms with a lot less rebound jounce.
