Outboard shock mounts - 6.5"-7" Rear drop
1 Attachment(s)
Dad and I are changing my truck over to an outboard rear shock mount. My truck is pretty low, and I wanted to run a rear bar, so the original shock mounts had to move.
I got the idea from the No Limit setup. - do you guys think this will work OK? |

Not saying it would be an issue but it's possible vs positioning a single shock stud @ the back side that allows the lower shock bushing to pivot vs bind. |

You're absolutely right..
Like this you're saying? So that way the rear axle housing has the ability to shift laterally as necessary |

I like this kit from Tinworks Fabrication.
Great quality built products and fast shipping. It keeps both shock eyes on the same plane. Similar to the NoLimit kit. https://tinworksfabrication.com/prod...tion-brackets/ |

Coil/Bag/truck arm/4-bar set-ups w/o a Watts Link to locate the housing will have side to side shift. While slight, it's still enough to create bind. I don't understand why they don't just re-clock the mounting points so the shock can pivot slightly side to side. |

So could make new lower mount like the top mount and then turn the bottom of the shock 90 degrees? Then it wouldn't bind if the rear end shifted a bit.

I am assuming that lolife99 is planning on installing an adjustable long track bar and a rear sway bar. Both those items will reduce the amount of bind from the lower shocks mounts as they will actively reduce how much the axle articulates. In suspension design every component's placement is a compromise between what helps, what hinders, and what is feasible under the design limitations. |

I always do the long track bar to the passenger side trailing arm and standard shock relocator. Tinworks Fabrication is a great company that is developing a ton of new products for GM trucks of several generations. |

The upper mounts are Ridetech. I got them from Summit. I think they were $20 or $25 each. They worked nicely. I'm going to give it a shot this way and just see how it goes. If it's binding in any way I'll rethink it.

To me, it seems like lots of shock angle with that Tinworks setup.Not what we want is it?

I ended up doing something similar using a set of modified Summit rear shock locating brackets. I only have a 4" drop but my rear shocks were at about a 30
degree angle. Just have to get everything painted up and pretty yet. |
Re: Outboard shock mounts - 6.5"-7" Rear drop
Kind of do not understand the thinking here. With a panhard bar the lateral (side to side) movement will be minimal. Especially with a longer panhard that is more parallel at ride height. Obviously, not a lot of articulation to worry about with the lowered suspension as suspension travel is limited. The change in shock angle even with standing them up more (as stock) will put more stress on the bushings more than lateral movement ever could. That is the reason GM put both of the shock mount bolts perpendicular to the frame. Put my rear shock mounts that way with 16" of wheel travel with leaf springs which will move side to side much more than a panhard setup. I will be able to bottom one rear wheel and have the other at full droop. Granted my shock eyes are a bit different with pivots in the ends. My case is extreme, I still hope I am getting the information stated correctly.

Is it possible? Sure. Is it a legit/correct statement across the board? Not w/o measuring. Even w/measuring, the parameters would have to be determined before the info is applicable (stock leaf vs stock T/A; dropped vs dropped). We know the T/A w/Panhard bar allows slight side shift by design. The shorter the bar, the more the shift. So if one is changing the stock shock location/positioning, it's not a bad idea to be aware. Monitoring for unusual wear & tear @ the shock mount bushings (oil change/maint intervals?) until they feel comfortable things are fine. |
Re: Outboard shock mounts - 6.5"-7" Rear drop
I completely agree it is a little questionable how it will function, so I guess we'll see. This truck won't see a lot of daily driving, so I'm not real worried about it to be honest.
I have tubular trailing arms and QA1 rear bar, rear links, double adjustable hiem track bar, 315s etc. I'm not concerned about hauling stuff, pulling a camper etc. This truck will be for AutoX and / or spirited driving. I want it to be a touch more laterally stable than vertical anyway.. forward bite being important too, of course. But I guess we'll see what happens. If it's not what I'm thinking it will be I will bag it or change over to coilovers. It is what it is.. (for now) |
Re: Outboard shock mounts - 6.5"-7" Rear drop
Took the truck for a ride today to see how the changes affected the ride and handling.
The body roll is much improved with the front sway bar added and I think moving the rear shocks to outside the frame rails and behind the Diff also helps with the body roll. Before my rear shocks were at around 35 degrees tilted forward with the 4 drop springs. Also, there was significant tire hop during hard acceleration. Now with them vertical to the travel of the rear diff travel there is ZERO tire hop but the ride is also firmer, not too bad for a truck but definitely not as mushy as it was. |

Sounds like you're happy so far. |

Next is to replace the rear trailing arms with some Summit tubular arms. Mine are twisted a bit and have a few holes rusted thru in them. |
