Re: 55-59 CPU Rear axle Flip Kit
you have to c-notch the frame and move the bump stops outside the frame
otherwise you will be constantly on the frame or bump stops

Re: 55-59 CPU Rear axle Flip Kit
Reasonably, 3+" from ride height is all you really need on the street. The shocks will be close to bottomed out anyway. opt.1 - use a sawzall and cut the bumpstop to appx 1/2" thick. opt.2 - buy some stud mount 1/2" thick bump stops and install. drill a new hole on the C.L. opt.3 - use the O.E. bumpstop, but make an angle iron mount to place it outboard on the chassis and higher.

Re: 55-59 CPU Rear axle Flip Kit
I removed the stock bump stops and replaced them with thick rubber (mud flap) pieces. This works really well, especially since I am running air shocks to give myself several inches of space between the axle tube and bump stop area.

Re: 55-59 CPU Rear axle Flip Kit
Just found this and it looks interesting. Buttt... When I went out and looked at my 56 there is a crossmember right where the rear shackles are riveted on. Are you guys who are doing this removing that crossmember ? I don't see one in the pics and it would also get in the way of the rear mounted gas tank. My truck is a 3200 series with a 123" wheelbase but I was planning to convert it to a short bed. Do I also need to move the rear crossmember rearward ? Post 1 the pic shows this crossmember removed. Post 55 (different truck) shows it still in place. Post 66, crossmember appears to have been moved to the rear. Clear as mud... What's the deal ? Removing it completely would severely weaken the frame and cause it to want to twist right where the rear hanger is attached. This is why GM put a crossmember in that location. Robnolimit what's the deal with that crossmember ? I realize that shortening the frame for the shortbed conversion happens directly behind the cab and is a completely different issue. My question pertains to the rearmost crossmember only. Thanks

Re: 55-59 CPU Rear axle Flip Kit
Thanks for the bump stop info guy... Think I am going to cut the factory bumstops off and mount them out board of the frame.
Another question.. does the No Limit kit have an offset ceter hole on the axle perch and leaf spring mounting plate? I basically fabbed up the same thing out of an old S10 leaf spring plate but the holes are centered. When i lowered the truck the wheel base measured 113 1/4". Factory is 114". Do I offset the hole and move it back or live with it? I moved the rear cross member back... but only to make room for the fuel tank. (idea i got off another thread). I plan on boxing sections of the frame to strengthen where the leaf spring perch is mounted. I just plan to leave enough access to get to the bolts if needed. This is my first automotive project though. Im a construction manager and am pretty good at working with wood and nails. This is my first time turning wrenches and metal fabricating... and so far i love it!! Thanks for all the info and help on here. Ill try to get some pics posted when it starts to look respectable. |

Re: 55-59 CPU Rear axle Flip Kit
the rear x-member is moved to fit a fuel tank behind the axle.

Re: 55-59 CPU Rear axle Flip Kit
When you consider flipping the rear shackle bracket upside down, understand that GM intended for the bracket to take the majority of the load and not the rivets. The rivets locate and attach the bracket to the frame rail, while the bracket, rails, and crossmember support the load. When you flip this bracket the majority of the load is placed on the bolts, not the bracket. The rear crossmember is placed between these brackets to prevent the frame from twisting and flexing from the load created by the outboard mounting of the leaf spring. You may never have a problem with this mounting, but know that when we modify things as we all do there may be problems. This is a cost effective mod, but it has it's drawbacks. 3 1/2" is a good axle tube to frame gap to shoot for. You may get by with less, but this is a safe spec. Notching frame/boxing can be a benefit here. Long wheelbase frames will need to be cut off at end when going short wheelbase, so remember when relocating crossmember on axle flip projects.

Re: 55-59 CPU Rear axle Flip Kit
TNBandit, I have a copy of the no limit tape, it shows (on a short bed) moving the cross brace back to another mounting hole on the frame, which I went and measured on mine and the hole is 3-3/4" back. your cross brace has some extra bracing on it ,more than likely due to being a long bed. I have some pics but site is doing some maintenance and can't load now. But they use the hole to locate it ,put a bolt in it to hold it and weld it in when done. They also show to box the frame from the shock mount crossmeber forward 16" to strengthen the frame.Was surprised they didn't install a C-notch , but now is the time to do it. It also , shows removing some springs and cutting the ones left to soften the ride. moving the hanger 3/4" forward rather than 5/8", anb to use FINE thread bolts and lock nuts , fine threads hold a lot better.
Forgot to mention with the frame leveled the pinion angle should be set at 2* down. Last edited by 1958Warrior; 09-14-2013 at 08:20 PM. Reason: add pinion angle |

Re: 55-59 CPU Rear axle Flip Kit
I followed up with Ogre's suggestion and got all the U bolts plates and hardware and axle seats local at Southwest Wheel (local trailer supply here in Dallas) got everything for $25 picked up (would've been $40 shipped) Saved me A lot of $$$, and Speedway has the lowest price I could find on the spring liner material.

Re: 55-59 CPU Rear axle Flip Kit
dang, i was ripped off
![]() i often refer to it as my $29 flip kit ![]() post up some pics as you flip it. new u-bolts, spring pads and a plate is all that is needed. this pic is when i was setting the pinion angle. that is the stock 58 shock bracket. ![]()

Re: 55-59 CPU Rear axle Flip Kit
I put a 2.5 on the front and a 4in drop on the rear of the 58 i'm working on. The rear is to high. What do you suggest to do to get it lower and level? Will the rear shackle flip do it or the full axle flip? Sorry about the pics. I only have two wheels so I had to do my best to balance it. As you can see in the one without the front fenders the rear is to high up.

Re: 55-59 CPU Rear axle Flip Kit
did you flip the axle?
If so, you could try longer shackles to get the rear down more. Might give you about 2" (additional) if I recall.... Also I saw a flip kit that required no welding. The bracket has 'legs' that fit into the axle spring perch. Are these pretty good/safe/reiiable?

Re: 55-59 CPU Rear axle Flip Kit
flipping the axle will give you approx a 7'' drop

imo... if you're going thru the trouble of flipping the axle go to a better gear and brakes

Re: 55-59 CPU Rear axle Flip Kit
Barn find,
i used 3" dropped springs from "The Truck Shop" in so. california, and made 1 1/2" longer shackles out of 7/16 plate steel. Dropped the rear 4 1/2 inches. it is still just a tad high, but it is all I can do unless I install a 2" C notch.

Re: 55-59 CPU Rear axle Flip Kit
all the other vendors make axle flip kits and charge $79 or more
put your own kit together for $29 (or $25 for 58warrior) ![]() like all other ''kits that don't require any fabrication, you can save a bundle putting together your own kit i can put together my own ss bed bolt ''kit'' for less than the steel bolts kits cost fyi, michael hasn't been at nolimit for years, pm rob, the owner if you need info
