They advise they work real well, but in researching this subject I came across Eaton Spring's advise against mono-leafs. My panel's not a hauler, I'd just like a smoother ride and a wee bit of lowering, 2 inches max. My other concern is wear on the U-joint with the stock torque-tube driveline, if the truck's lowered it will be flexing differently than designed for. | | | | | Joined: Aug 2002 Posts: 455 Shop Shark | | Shop Shark Joined: Aug 2002 Posts: 455 | I got front monoleaf springs from CPP on my daily 1/2ton 52 chevy for 3 years now.
I drive freeways, city and bumpy dirt roads and can only say the very best things about them.
They have even more travel than the original (worn) ones and I never bottomed out.
I never worry about them breaking sooner than any other critical part under stress.
Like Eaton springs says, if springs are properly designed there is not a problem. These seem very well designed and could handle a lot more load.
I think Patricks sells the same ones and gets them from CPP.
On the rear I kept the original multileafs but used lowering blocks from Jim Carter. | | | | | Joined: Mar 2005 Posts: 1,513 'Bolter | | 'Bolter Joined: Mar 2005 Posts: 1,513 | I thought I wanted monoleafs but first I tried removing the 2 bottom leafs out of the spring pak. I got more or less what you say you are looking for. The leafs are 1/4" thick so removing two gave me 1 1/2" drop of bumper height and a stance that I'm happy with. The ride smoothed out a whole bunch too. It only took one evening and a few washers under the u-bolts so it's worth a try. I was suprised the steering wheel changed 1/4 turn so even this minor alteration has quite an effect on steering geometry. Don't worry about the u-joint as lowering actually straightens out the drive from the tranny to the shaft.

You don't want any poorly designed or manufactured parts in your suspension. But I am not persuaded by his arguement that monoleafs are inherently dangerous.

It's true. I really don't do anything but browse the Internet looking for trouble... | | | | | Joined: May 2004 Posts: 351 Wrench Fetcher | | Wrench Fetcher Joined: May 2004 Posts: 351 | Patrick's has the multi-leaf with a couple leafs taken out. Drops the truck about two inches.
Question though. With a 2" drop does the Pitman Arm need shortening? | | |
