How to gain additional 2" of usuable suspension travel
This is for the guys that have a 2" or 3" drop spring on the front of there trucks, and have the trouble of bottoming out quite offten.
edited... now an attached image. If you look at the pic posted above (borrowed fromm Avtekk) you will see the blue line drawn on the factory bumpstop, you will want to, with a hacksaw, cut the bumpstop down to this line, this alone will give you more suspension travel. NOTE… you will not gain anymore travel by cutting down past this line, or removing the bumpstop totaly, to gain additional travel you will have to do some cutting... Look at the red line i drew on the back side of the frame, when the bumpstop is removed totally, this is where the lower A arm and the frame would make contact, to solve this problem you can cut this part of the frame out. By cutting the frame on the red line, this will alow the lower A arm to come up higher into the frame. After the part of the frame is cut out, you will want to raise the A arm up until it stops on the frame, this will check to see if it now clears better, you may need to do a little grinding for a nice fit. By cutting the frame out here, you can now run a very small aftermarket poly urthane bumpstop, and not here that annoying metal on metal sound. Last edited by 98layinframe : 10-06-2005 at 10:35 AM. |

the only thing you can do.. remove them! but your going to have all kinds of fun relocating the stuff on top of the fenders, and make sure to cut the inner part of the fender out also.

Re: How to gain additional 2" of suspension travel with spring drop look here.
and what is with the firmness if you cutting the frame? i think it brokes with the time!
can you tell me how high the spring rate for 1, 2and 3 inch springs is? can ' someone show me a picture like one ěnch feather/spring out-looked if the car on the road stands? if one only bumpstop cuts is enough the place between A-poor and frame off if bumpstop is strongly pressed? and can that happen easily? i`m german sorry about my english! |

Re: How to gain additional 2" of suspension travel with spring drop look here.
is it necessary to strenghten the frame back up after cutting out that 3/4"? i dont have any clearance probs with my 4" front, but im going to 5" in the spring time and i dont want to be bottoming out like mad, and it looks tight under there right now

Re: How to gain additional 2" of suspension travel with spring drop look here.
no it is not nessary to brace it... actually if you look on air lifts website, this is one of the locations they tell you to cut out when bagging a truck. You are not cutting any major part of the frame, it is only a small part of the lower lip.
and s10 heizer - im sorry but its kinda hard to intereprit what that all means, but as the the spring rates, a 1" spring is almost exactly the same as a factory rate, the 2 and 3" srings are where you start gettting in to the higher rates, and so need a stiffer shock to provide a quality ride. |

Re: How to gain additional 2" of suspension travel with spring drop look here.
How long have you been driving around w/ your frame cut like that? Any problems? For some reason that just doesn't seem safe to me. I've got 3" coils on my blazer and it bottoms out all the time, so I'm kinda desperate for a low cost solution.

Re: How to gain additional 2" of suspension travel with spring drop look here.
instead of cutting the frame, you can also cut the hump off of the LCA. Then weld in a new piece of steel to make it flat. Here you can see the hump was shaved off the of the LCA in order to lay frame with bags. This will also gain you clearance when running 3" drop coils. http://img.s10forum.com/album2386/aba.jpg |

Re: How to gain additional 2" of suspension travel with spring drop look here.
 you will be just fine cutting out a little tiny spot in the frame like that. As for how much i have cutout... im bagged... that should tell ya right there.Heres a pic of my frame pocket from underneith. The entire opening around the pocket is removed and a good 2" up the outside of the frame rail is cut out to clear the bag.  heres a pic with the frame trimmed and the humps removed from the lower control arms... the top of the ball joint almost reaches level with the top of the frame   Last edited by 98layinframe : 07-19-2005 at 09:30 AM. |

Re: How to gain additional 2" of suspension travel with spring drop look here.
I used the Belltech suspension lowering kit 2"front 3"rear. I don't bottom out, but my ride is so rough when i go over bumps. I'm still learning about this stuff. Does this thread apply to me as well? Or is there something else I can do to smooth out the ride over bumps?

Re: How to gain additional 2" of suspension travel with spring drop look here.
If you are droping your rig that far and removing your bumpstops wouldnt you need differant shocks to keep the old ones from bottoming out?

Re: How to gain additional 2" of suspension travel with spring drop look here.
Might as well revive this thread again but i was wounderin if you "98layinframe" had any of the pics that you previously posted. Because now they dont show up and im about to bag the front and was lookin for some visual aid so if you can post some more pics it'd be awesome.

Re: How to gain additional 2" of suspension travel with spring drop look here.
sorry my old computer crashed awhile back and i lost a good bit of my pics.... but i did manage to save some to a cd before hand, so hopefully there on there. I'll try and find the old ones. But for now, heres a pic I have, i recently recut the back side of the pocket out and moved the wall back some to accomidate the bag better and to offset it more towards the back of the spring pocket for more usuable travel range out of the bag. Also the upper bag cup is just hanging there by a few threads of the bolt, when the bolt is tight... the top of the roll plate just about touches the top of the frame cut out there and sits even with it.
Long story short... heres a pic of my frame with a 2b7 bag hanging in there. Gives you sorta an idea as to where was cut. Also the little angled section on the front of the pocket by the tierod notch it there to clear the lower control arm when laidout. Hope this helps you guys a bit.
