New Leaf Springs

[lgvl]

After removing my bed i noticed some broken leaves in my rear suspension and am wondering what the best supplier is for a whole new, unrusted, leaf pack? I found these at General Spring, http://www.generalspringkc.com/Leaf_...991_s/1833.htm. Any opinions? Thanks.

Are you wanting to go to a better ride quality and not tow much? You night be able to get 1/2 ton springs they're a little more forgiving than 1 ton's. that's actually where i got mine from. Figured 300 for both will last me quite a few years. Not i'm combining my 1/2 and 1 ton for about 14/15 leaves. > serious towing capacity.

Im trying to keep the truck as stock as possible so keeping the truck a true 1 ton is important. Thanks.

I bought mine from here but the place you linked looked like good prices

check jcwhitney too they sell the same leafs

If picking between those two sites. Pick the cheaper of the two. If you notice they use the same part numbers, so I would assume they are both selling the same springs.

How come the 1 ton rear springs range from 2600 to 4650 lbs? If you look under the 3/4 ton you will find up to 2600 and 3500 lbs.

So what would he factory 3/4 and 1 ton spring rate be?

I put these in my 1990 SRW one ton. Shipping cost around $150

Measure your existing pack thickness (while its still bolted to the axle) before picking your springs if you do not know what your existing springs weight rating is. You may not want a lighter spring than what you have, and pack thickness will be your only way to know which pack to select.

RPO code for the rear suspension tells you the weight rating of your rear springs. SD Springs sells their springs based on RPO code.

Thats all fine if 1. Your SPID is there 2. Your truck is still wearing its original springs.
(1.My SPID was already gone when I got my truck 2. my 1/2 ton is not wearing 1/2 ton springs. Took measuring the pack thickness to get the correct spring becuase not all 6/1 springs are the same, Not everyone wants to lower or soften the ride).

Example: You have 8/1 spring pack on your truck. Just happens to ride how you like and handles the loads you throw at it just right. Problem is, you didn't install them initially, how will you know which one to get in order to maintain your current ride?;

Alternately, you want to soften your ride a bit, but not a lot, still have to know what you are starting with.

I'm in the same boat on my Suburban. Trying to find new rear leafs. Will the pack thickness or load rating affect ride height?

Yes.
Pack thickness a minor amount (all else being equal, 1/2 the thickness in the difference in pack thickness. So a 1" thicker spring pack will raise the rear 1/2") Unless you are going extreme heavy duty, pack thickness differences is minor.

Load rating definately. A heavy duty spring pack will squat less than a light duty spring pack even unloaded (depending on what the original application of the hd spring pack was).
A light duty pack will squat proportionately more than a heavy duty spring pack as you load it up. If you routinely carry gear, and don't like the tail dragger look, go up to a higher rated spring (at a cost to ride, so if that sort of thing bothers you).

Count your leaves. Measure the thickness between the spring mounts (pack thickness) and measure your spring length to see if you have 52 (same length front eye to axle and rear eye to axle) or 56" springs (unequal lengths between axle and spring eye). Determine what you have and make a selection on what you are after. (ie: softening up the ride at cost to load carrying, or ability to carry more without squatting the truck).
