Anyone have any experiance cutting coils.

Anyone ever tried cutting there high lift coil spring to drop a few inches of lift? to be exact brand new 9inchers down to 6.5s or so.

cutting coils increases the spring rate and is not advised.

Why not run a ad and see if you can trade with somebody?

What Pete said.

 

I haven't done it with an MJ or XJ, but when I was building my AMC Javelin budget race car I made my own springs. The rears were two pairs of stock springs, shuffled together with every other leaf cut off to make the lengths progressive. It made them stiffer (which was what I wanted) but also lifted the rear about an inch (which was not wanted), so I added a 1" lowering block on each side.

 

For the front I cut either two or three coils (don't remember which). This dropped the nose about an inch and stiffened up the stock springs enough to improve the handling significantly.

thanks for the advise guys. i went ahead and ordered some correct springs today and a rear shackle to add one inch to the rear. Plus i plan on doing the spring over real soon aswell. ill post some pics before and after the install. Might have to start a build thread i guess :cheers:

I chopped down my Rubicon Express 4.5's a while back.

They were giving me (IIRC) ~5.25",

chopping them dropped me an inch to ~4.25" (again, IIRC).

 

Cutting them meant I chopped off the flattened portion of the bottom of the coil,

but the coil end still bolted in fine to the lower coil bucket clamp.

 

As far as spring rate,

cutting down coils does raise spring rate.

 

But with these particular coils,

if it did increase, my butt-o-meter sure couldn't detect it.
