Replacement Leaf Spring Questions
I am looking at buying new leaf springs for my Blazer. My goal is the smoothest ride possible with just a minor lift. I am running 33x10.5R15 BFG AT KO2 tires on some 15x7" slots from a 70s Jeep Wagoneer.
I went and spoke to the guys at Deaver and unfortunately they wont build a 2" lift leaf pack. This was disappointing, but they dont seem willing to build a custom pack for me. Oh well. Only 4" which is too high for my needs with tire size and light offroad duty. So now I'm considering the following: A) Skyjacker 2.5" lift spring set. These would be a little more lift than I want/need, and I'm assuming they'll be stiffer than stock. But I would consider removing one or two leaves from each pack to soften them up and lower just a bit. Question #1 for anyone using 2.5" lift Skyjacher Springs is: how compliant is the ride, compared to stock springs? Would you recommend them? B) Replacement stock leaf springs from generalspringkc, sdtruckspring, etc. Coupled with a 1" zero-rate. Question #2 to those who have purchased stock replacement leaf springs is: Are these springs 3" wide at the eyes, and have tapered thickness, like the original springs? I've done a little searching but havent seen a definitive answer. I'm wondering if they are just straight 2.5" wide like aftermarket lift springs. It is my intent to run rubber bushings in whichever set of springs I go with. I appreciate and help and answers to my two questions! |

I have zero lift, stock height springs for my Blazer and K20 from Alcan Spring - same width as oem. The packs use more leaves than stock but are thinner - ride is much better than the old springs fwiw. Get some Teflon spring liners to replace the oem plastic liners between the springs and perches.

I purchased The Tuff Country front springs with an advertised lift of 2". I installed them and it lifted the truck 3 1/2". Too high for me!
I took these new spring in to the local spring shop and had the de-arched a couple inches. The rear springs were new off the shelf items, and I used a 1" spacer block to level the truck. The ride is awesome! When I did the new springs, I also added a 73'up sway bar in the front. The combination of new springs and sway bar improved the ride and handling 10 fold, and is absolutely the best modification I could have done to my truck. Here's a link to a post I made a while back. Some of the measurements may help you. http://67-72chevytrucks.com/vboard/s...d.php?t=754525 |
Re: Replacement Leaf Spring Questions
There are a couple of shops down by me that would build what you want. You are about an hour or so north of me so not a terrible drive for you. Let me know if you want info and I will get it for you.

Just curious, have tried the wheels yet? If I remember correctly I had relive the backside of the wheels. The edge of the rear brake drums were hitting the backside of the wheel.

Hemi43, did you document the sway bar install? If so, please share the link.
Thank you |

As far as mounting at the axle, you will need the 71`up caps that go above the axle. They are the same as the older style but have a threaded hole for the sway bar to bolt to.You could in fact use the older style caps, but you`ll have to drill and tap them so you can bolt the sway bar to them. I regret now for not taking pictures of it. |

I believe Atlas Suspension in the City of Industry can make you a custom pack that will perform just the way you want. http://atlassuspension.com/

I did in fact get a set of 33x10.5 BFG ATs and mount them on the Jeep slots. I have 1.5" wheel spacers on the back, so I'm not really sure if there would be interference with the drum. On the front, they did lightly kiss the bent edge of the caliper mount bracket so I had to grind the edge off of the brackets. But I really like that these wheels have a nice neutral offset and with the 10.5" section width tires the handling and steering is much improved. For me, high offset wheels look great, but handle terribly. What I also like about these is that they mount with a standard 60-degree taper lug nuts, rather than the shoulder lug nuts used on the normal mag wheels. |

Thanks! I forgot about Atlas. Its nice that they're local so I wouldn't have to pay hefty shipping. I'll have to give them a call this week and see how they build the springs. |

I’d guess a good 1” if those are oem springs. Here are mine w stock height Alcan springs and 33” tires.

Re: Replacement Leaf Spring Questions
Have been told by several sources that Deaver or Atlas do not build their own springs anymore. It may have something to do with running the kilns here in California, maybe costs as well. It is my understanding their springs are made to spec for them. Both company's stand behind their product. Benefit to going with either one (as you are within driving distance) is they still do tune and modify on site. Will be using a Deaver spring from the later Chevy truck on my truck. Fully expect to need it modified. As my build is custom, even if I had specific springs made I would still expect to need them adjusted.

Re: Replacement Leaf Spring Questions
Not sure if anyone mentioned this but I had Off-road Design build me a lift with a rear shackle flip. I went with 3” total lift but they offer 2”. They have the springs custom built to how you want the ride. It’s a little pricey but not insane.

With the shackle flip bracket they can tune the lift height, using Deaver's typical 4" lift springs. |
