No-limit relocation kit shocks at an angle Why ?

[Trevor]

I'm researching my rear shock relocation options, and I like the looks and theory behind the No-limit outboard mount location, but don't understand why the upper mount is placed so far back that it puts the shock at quite an angle and therefore in an arc opposite to that of the trailing arms arc (a double no-no).

Is it to maximize shock length ? or does the stock panhard bar frame mount interfere ? Or is there something else I'm missing ?

I may just fab my own so any insight would be appreciated,

On their website, they have an article (it sounds like it was written by a 3rd party magazine, but it doesn't give anyone credit) about the install:
http://nolimit.net/tech-center/67-c1...on-kit-1963-72

In the article it says:
"By far the biggest mistake made by the engineers at General Motors during the early sixties was the shock placement on the trailing arm suspension. But who knew that these trucks were going to be pushed to the limits of performance driving. No Limit found the cure for the shock placement mishap that gives C-10 enough “body roll” to make someone sea-sick. By re-locating the shocks “outboard” rather than inboard of the frame, your C-10 will become more stable in the turns. Also by moving the shocks behind the axle, they complement the ride quality as well as they can now control the “wheel hop” that many trucks are prone to."

I know zip about suspension geometry specifically, but their flowery speech sure makes it sound awesome.

Well I have the kit on my 71 and I'll say this. The truck handles way better and I have min body roll.

Never seen or heard this, this is why we love this forum Thanks Andy for the feedback and pics, I will be ordering mine soon

It actually keeps them more vertical .........

Got this kit on my 63 with 5 in drop coils in the back. Love it rides better than stock 😎 as far as the angle Idk I'm not that smart. I'd say something to do with the travel of the trailing arms, they have a fulcrum point where they attach to the frame, making the rear end travel at a radius instead of completely vertical up and down movement. I'm sure it ant much of a radius but I assume the angle is the best compensation for that....? Or there was just a reference point hole there to go off of for the customers ease of installation. Lol not sure just my thoughts good question

[im4darush]

Have this kit on a bagged 68 SWB and the difference in ride/handling is very noticable.

Subscribed to remember these. This looks like a good option instead of having my rear shocks dang near laying flat to the stock mounts with a lowering kit.

Other than the LS motor and cruise control it's one of the best mods on my truck!
By the way I took the rear sway bar off the truck after installing it.

I am curious to know at what point you need this done? Nobody has said any thing as of what the amount of lowering was used like for a 1" lowering or a 2" lowering or a 3" lowering and so on 3", 4", 5".

I guess my point is at what point does the Suspension need the shock relocation done to correct the problem when lowering these trucks rear Suspension as much as some people like them.

Mine I will be using only a 2" lowered/dropped rear Coil Springs and the fronts will have only a 1" lowered/dropped Coil Springs.

Will I be OK with my small drops or will I still need to do the Shock relocation deal? My truck will NOT be going into turns at High Speeds at all, its a Truck not a Corvette! It does look like the information above is useful for the Extreme Drops.

[Wingnut Way]

Kit is for any ride height including stock. Different drops different shocks. Affects ride quality greatly. Suspension geometry bla diddy bla bla. I recommend the kit works great

[Andy4639]

Mine was for 4" drop static in the rear.
The kit itself is worth it even for a stock ride because it moves the shocks to the outside of the frame for better ride quality. Hardly any body roll at all.

Outside of this kit, they recommend shock relocating at 4" or more drop. The other options help correct the angle in original location. This kit is newly engineered to locate shocks outboard like on newer vehicles, which is a benefit at any height for stability, and a correction for lowered angles.

If just wanting to re angle the rear shocks I wonder if this Kit from Brothers would work just as well.

For the difference in price go with the No Limit kit. Much better kit.

[Wide Open]

These are only made for 2WD trucks I take it?

[Wingnut Way]

Trailing arm setup only. I think all K trucks were leaf correct me if I'm wrong

[Wingnut Way]

I wouldn't say all half tons ether, gmc were leaf also if I recall correctly

[dflarsen77]

Here's the post when No Limit first made them:
http://67-72chevytrucks.com/vboard/s...d.php?t=444925

Interesting stuff. I really didn't know about these, but now that I do, I'm definitely going to get them. They cause a scrub line issue though. If you want to use drop blocks, and this kit, you'll need a 17" wheel or more.

[Wide Open]

OK thanks. That's what I figured after reading the article and only mentioning the trailing arm/coil suspensions.
Would be nice to move the shocks outboard on the leaf trucks too. I suppose something can be fabricated.

[elf w/capital T]

very smooth, just make sure to get the right shock length

[Boyd67]

I'll have to try and remember these no limit ones when I lower my truck

[70cst]

This would be right up "WES"'s ally ...

Yup, it's true that shocks outboard of the frame rails offer more stability. They work great on leaf springs trucks, but one of the reason's GM engineer's likely never installed shocks this way is lateral movement. When these trucks were new they had skinny tires that were inches from the wheel wells. When a truck is loaded, or just during everyday driving, the rear end is moving side to side as it moves up and down, whereas in a leaf spring truck, it can only move up and down. The reason GM tilted the shocks inside of the frame rails is so the shock essentially moves side to side with the rear axle as it moves up and down. They gave up stability for longevity. If you look at the leaf spring rear trucks of the same years, while they are mounted inboard of the frame, GM put the shocks dang near straight up and perpendicular to the ground because the leaf rears had no lateral movement.

I can see potential wear issues with this kit, and as mentioned above, I could see how the holes on the lower mount could possibly become wallered out from all the lateral movement. But, with all that said, that would likely take a long ass time, especially since *most* of us probably only drive these beasts a few thousand miles a year to dairy queen and back. Again, with that said, I'd be interested in this kit if I didn't already spend a ton of money on my ECE kit and new shocks... I wouldn't be able to address my ECE adjustable panhard bar mount with this kit either.

*Just trying to defend my fellow engineers from back in the day

*Assuming the bed still fit (and with mods anything will fit, I've seen floors a few inches from the top of a bed) the shock placement on the green truck above is about perfect. The shocks can move freely "side to side" by going up and down through their cycle, no side to side wear.
