Leaf spring install tips

(Posted here and Autocross/Roadrace section for exposure)

I'm going to replace my stock springs tomorrow and will be using the instructions found at LS1Tech. If you have any additional cautions, tips or suggestions please post here.

Thanks,

-RR

Arthur, what springs are you putting in? I've got a set of Z06 in the garage to put on now.

Hey Kevin,

I'm installing Hyperco springs. Specs are:

Rear - 777 lbs
Front - 571 lbs

They should be a perfect match with my Koni FSDs.

You may want to adjust the front spring adjusters in as much as possible and it will help you slide the spring out. I had a brutal workout removing mine...but it was the base spring (more arch). Other than that, you'll be fine.

Like the others mentioned here, LS1howto's instructions made life easier. Pretty easy job. Especially the rear spring.

I finished the install and it was very easy and straightforward. One tip I will add is to put some anti-seize on the threads of the front ride height adjusters. My stock ones are still imovable and may require some vise grip action to get them to turn. Anyway, I haven't driven the car yet because of the pending T-Storms in my area so a review will come later. Also, while I was at it I changed the brake pads to Hawk HPS and did some more undercarriage cleaning.

Here's some weight info for those who may care.

Rear OEM springs - 12 lbs
Rear Hypercoil springs - 12 lbs

Front OEM springs - 9 lbs
Rear Hypercoil springs - 10 lbs

Pictures below show the difference in the curvature of the OEM vs the aftermarket.

Enjoy!

Thanks for the report on your install, glad the anti-sieze instruction we have in our install helped. And thanks for the pics!

No problem Tom, however I must confess that I could not find the install intructions on your site. I came up with the anti-seize after seeing what happened to my stock adjusters. Definitely a great idea though. By the way, these springs and the Koni FSDs are the perfect combination. I'm posting a review in the general forum section now.

If it's not too expensive I may look into the same setup. The roads here suck!

Honestly it was one of the least stressful mod projects that I've completed. Give me a call if you need any tips but it's really straightforward.

Very simple. Got them on this morning. Total time 2.5 hours.

Thanks Arthur!
