Ok so I went to start with a bed bob a realized I had no extra bed to bob do to the loooong 63"chevy springs im running so here is the experiment im trying

Im moving the front spring mount another 8" forward a total of 19ö form stock allowing me to utilize the stock shackle mountin the back.

As to fit the tire in the wheel wells Im moving the axel back 6ö on the spring. (not 8ö because my tire sits a little rear already). to do this I plan to take:

The main leaf and drill the pin hole 6ö further aft on the spring
The center leaf and drill the pin hole 3ö aft of is stock hole
Im gona will use the stock hole on the bottom leaf and on the overload.

I plan to cut a 3/8in bolt into pieces slide them in the old pin holes weld and grind it smooth

After placing a 6* shim I believe the axel will be pretty strait under the spring.

This should allow me to cut the frame right behind the spring mount. Allowing me to bob like 13in of my 85 x-cab box.

Also the axel being even farther back on the springs that (in theory) allows for more travel so I can get rid of these [email]f@%$ing[/email] dual shackles and still be really flexi

If there is a serious down side to this that im not seeing lit me know fast but if this doesnÆt work im just gona buy a set of trail gear rears and be done with it.

Ill let you all know how it turns out

I thought having the axle closer to the center would give you your most flex... That would make sense geometrically, another thought though rather than all that trouble why not bob the bed from the front as well so that you can center the wheel well where needed?

The leaves are likely to break where the old holes are (or were). Your flex won't be as good as before since the axle isn't in the middle of the spring where the spring rate is lowest and the travel is "most-est."

I'd say you're far better off just running some decent shorter springs.

that makes sence but wouldn't it be better farther away from the hard mounted part of the spring as long as your shackels arnt maxed out

that would shorten my wheel base. i might as well... dare i say it... buy a jeep <img src="/forums/images/graemlins/lol.gif" alt="" />

I run chevies with a long shackle in the stock hanger. Why can't you do that?

Erik is right. You drill that leaf and you'll break it... and since they chevy's have no military wrap, that could leave you in a world of hurt.

Go w/ shorter springs.

Can you say......"d*mn, where'd my axel go?"

Likely, Darwin would get 'im on the highway at 65mph.... and it'd only be one side... so I don't think wondering where his axle went would be the frist thought in his mind as he crab-walks at that speed. <img src="/forums/images/graemlins/lol.gif" alt="" />

What about S10 springs? They are what, 53" or 56"? That would compensate it right?
