Replacement Srpings

[THI]

I need to update the springs on my 1978 GMC K25 (3/4-ton 4WD), main concern is the front springs. I currently have the 2-leaf front springs and am looking for a good replacement, but the rating on the replacement 2-leaf is 1,200# and from what I can tell the factory rated their 2-leaf pack at 1,800#. Does anyone have experience with the stock height replacement springs? After over 40 years they are sagging so I need to update, but want make sure I actually have the right capacity. I see the 4-leaf replacement pack is rated at 1,900# and the 3-leaf pack is rated at 1,400#. My experience with the factory 3-leaf pack was it was very stiff unless you had an all iron big block or a plow up front so I am hesitant to go more than the 2-leaf, but do not want to under spring the front.

I want to keep the ride reasonable, but will do some work with the truck - it is a 3/4-ton after all. It will from time to time have to haul a load of firewood, but will most likely be used to take my 14' fishing boat to one of the local boat ramps. I have 55 acres about half wooded and will be used to do some work farm occasionally. Driveline is a mild 400 (with Vortec heads), TH400 with an NP241 t-case, Dana 60 front and 14-bolt rear with 3.73 gears. Please let me know what your experience is with the replacement front springs. Thank you.

I bought the 3 leaf Dayton/Stanley springs 5 years ago. 454 K30. I love them. Added a 250# bumper. Still love them. 2 for 1/2 ton is what I would do. I can run over a dime and tell you if its heads or tails but it handles great.

Thank you for the responses - very helpful! Looks like I should go with the three leaf pack

Talk to Joe @ General Spring KC.

I used General Spring for replacement springs for my C20 Camper Special, I do like their customer service! Plan on ordering through them again.

I just go down to my local spring shop and tell them what I need based on application. They make them up and hand them to me. Sometimes I tell them to add as spring if I want to. I always go at least 3 for both 1/2 and 3/4 ton.

Go with the softer ones. 3/4ton or not you sound like you won't be doing anything more then a 1/2ton would be able to do so go comfy.

even if you buy the 3 leaf if its to stiff just pull a leaf out of each pack .

lots of times its cheeper to buy the hd pack option and do just this . i know it from me doing it and years in repair work the shops do it all the time .
