Rear coil spring bow after installing TGC 1.5” and Airlift 1000

[Maverick27]

Just recently installed my TGC rear coil spring spacers and Airlift 1000 bags along with Mevotech UCA and Bilstein 5100’s set to 2.8.
My question still remains, even after looking around the site. Is it normal for the rear coils to have a bow to them?

You sure the spacers go on the top? I have different spacers, but they went on the axle. Is the coil seated all the way on the axle and up top?

That looks normal. I would clock the spring in the exact position they came out. Grab a picture while the spring is under load

I have a pair of 1/2” lift spacers in mine that go up top like yours. I’m also running 1” lift springs so I’m sitting at 1.5” lift and have no issues. Make sure the spring is in the correct orientation. May need to rotate them so your lower coil sits to the rear which will push the coil springs forward

Yup, there is a mounting bolt for the spacer on the top coil perch. As far as I can tell, the coils are fully seated.

I’m not 100% sure I have the coils clocked correctly by the looks of it. This is with full vehicle weight on the coils. Drivers side is pictured first.

Any chance you know the factory coil orientation? Any pictures? I think they are just clocked wrong.

After some time adjusting the coils, here’s my results. Drivers side pictures are 1-2 Pass. Side is 3-4

Drivers lower coil tail is located roughly at 11 o’clock from the rear locking down.
Pass. side is roughly 6ish o’clock from the rear looking down.

I’ve read that these coils are different heights from the factory, could that be the reason they are clocked differently?

Also, pictures are with the truck sitting just on the floor jack, so there is full weight in the rear suspension. Air bags are deflated.

That looks a lot better. Clocking the springs makes a world of difference

I’m happy with it lol. I talked with another guy that does a lot of suspension work and he said it’s the nature of the beast when installing coil spacers. As he said, “it’s to be expected” because the spacer moves the axle lower in its range of motion, which misaligns the spring perches.
Only real fix would be adjustable control arms or a mount relocation kit, but I’m going to run it this way and see how it goes.
