Coil-overs: QA1 vs ALDAN

[Jglew82]

Thank you for explaining, makes total sense as I didn't think about the stock spring perch and pressure points .

Not sure if anyone might know the difference between the two single adjustable 700lb coilovers that Aldan offers #300132 and #300220. Website says #300220 is for custom control arms but I'd like to know what that difference is between the two coilovers, because if it is only the length, it'll affect the drop I can achieve

They should be the same, but I'd give Aldan a call to verify it.

Yep, call Aldan or Pro Performance (in Arizona), they were super knowledgeable with my OBS set up!

so i called Aldan and they said that the #300220 coilovers are about an inch shorter in length so in theory, they should add an additional inch to the drop range. Trade off is that the max height setting is also an inch less when compared to the longer #300132 coilovers.

I overcompensated for the drop when I first put mine in... had to lift it about 1.5 inches - she still sat low but rode like she was on rails... I love them- I will get another set for my current OBS eventually... sold the 98 that I put the Aldan's in.

I can't believe I missed this post.

I have a super early set of Aldan American coilovers on my shortbed. They've been on there for 4 or 5 years now. Still in great shape, no issues.

I love the ALDANs... no issues here! when I get my tuning on my SS done, I am gonna convert it too.

I put a set of Aldans on my 93 C1500. They went on easily, and work well, but adjustability is tough. I don't know if it's the pressure from the spring or what, but I was barely able to move the ring at all after installation. I guess you'd have to pop the lower control loose, thereby giving some relief to the spring, to adjust them properly and without struggle. Other than adjustability, they seem to be of really good quality.

Would lifting the truck up so that front wheels are off the ground make adjustments easier?

Do you have the thrust bearings installed?

Yep... gotta have thrust bearings and lift it up to relieve the tension on it.
