Spirson makes a nice product, no doubt in that but its more of a lift than a suspension system. I'd put them between Carli/Thuren/Kore and Fabtech/ProComp/Superlift. It can cruise the malls just fine and do some good offroading but I would never have it on a chase truck, let alone put it in a race.
Hello to all. A friend of mine pointed me in the direction of this thread to see if I could answer any questions about my truck.
Those of you that are not familiar with the Spirson System should take a look into it. I think you would find its quality and performance to be right up there with the Carli / Thuren products.
Some have made comments about being able to fit 37" tires with less lift, while this is true it can be done, with the 6" system you can pretty much fit any wheel and tire combo (37") and not have any rubbing or touching anywhere, not even the front valance. I know when using less lift it is imperative that you have as close to the factory BS as possible and things still need to be trimmed / clearanced to fit the larger tires.
For the comment about the 20" wheels being "bling". Yes, they are. That is how my wife drives the truck daily. When we are going to use the truck offroad I have 37's on 17" wheels and it does help.
For the comment above about not using as a chase truck or a race truck, I'm not sure why you would say this.
A race truck it is not. Could the suspesion be used on a race truck, sure, it is definitely HD enough and works extremely well. Would other things need to be done to reinforce some areas, you betcha.
A chase truck now, it surely could and does to an extent. My suspension has seen many miles of dirt / sand /clay / rock / shale / etc.. While I'm am not abusive to it, I have not had any failures caused by the suspension.
Anyway.... Just wanted to comment on a few of the things I read. If you have any other questions I would be glad to answer them.
