Re: shock hardware HELP

I have never seen a bolt on with a 1/2'' shaft. I have seen these though. But you have to weld them.

The only other thing is using a 1/2'' grade 8 bolt

Re: shock hardware HELP

My local parts house has them. They usually come with new shocks when you buy them.

Re: shock hardware HELP

Well, What happens is they get lost during rebuild or don't come with Bilsteins or like I did last week the top front shock mount torque spec is 140 lbs and I stripped one getting to spec .

Re: shock hardware HELP

Grade 8 is a poor choice for this application. They are too hard and will snap in two with side loads. Grade 5 fine threaded is a better choice if you can't fine the proper bolt. I know NAPA has them.

Re: shock hardware HELP

If a shock absorber breaks a Grade 8 bolt, you've got a whole lot of other issues going on

Re: shock hardware HELP

What shocks are you trying to fit onto this truck? Part Number and brand please...

I have never seen a 1/2" top mount shock for one of these trucks...
The aftermarket ones from QA1....which include the mount brackets etc are half inch but fit only the QA1 shocks...and require the chassis to be drilled etc...

All standard replacement shocks and standard style support brackets I have ever used have 5/8" holes....

the bottom here lies the problem as you can see 1/2 inch drill shank fits not as snug as I would like same as the 1/2 grade 8 the last picture is down were these will eventually be bolted to my lower c-arm which I believe stock A-arms uses a bolt and thats why again I think they don’t provide this hardware I did go to speedways web site an ordered what they had available as Grumpy showed me that path.... and then KQQL It also showed me on eBay a aka p-19 im hoping those are more snug than the 1/2 inch bolt short money in the scheme of things ..... got the picture....a little sarcasm from me and if I do happen to use a grade 8 down there and break it I agree I got a bigger problem and I am taking the advice on a grade 5 fine thread makes cents $$.... so to be continued when those studs (ill call them )show up if anyone else would like to chime in Im all ears
thanks again
Jess

Re: shock hardware HELP

Grab yourself some 13 MM grade 8 bolts and nuts...these are approx 1/64 larger than the nominal 1/2" bolt diameter...

13 mm measure 0.51181102362 or 0 33/64 over 32/64 which is 1/2"...


Hope this helps you out...

but...

The entire new shock unit incl the stud and nuts etc is $38...per shock...

https://www.amazon.com/KYB-KG5409-Ga...ype=automotive

Note....Suggest strongly that using a 1/2" bolt you should seriously consider using an aftermarket secondary support to the outer end of the stud....

Hope this helps you out...


i think i posted some mor info and this crossed....in the middle im not missing anything they just dont provide any hardware for the botom if you have a stock a arm i believe from memory and im old they bolt to the control arm

Hope this helps you out...

update as promised... so today I went to my local supply house who has a very large inventory of nuts, bolts all lgrades and sizes and if they dont have it they can order it .... to my suprise I was told by the counterman that ''They dont make 13mm bolts" he can give me a 12 or a 14 no 13mm. So if anyone knows where I can get 2 grade 8s 3 inches long with 2 washers 2 reg bolts and 2 nylocs bolts I would gladly pay to take that 1/64 little bit of slop out...this is for the bottom of the shock where it attaches to the lower control arm. I did search on line and no results it kind of backed up what my counterman said ??
thanks
Jess

Re: shock hardware HELP

Ok....13mm shank diameter bolts are a special aircraft size and very difficult to obtain...normal supply houses dont carry them.

Perhaps I should have made that more apparent in my response....apologies...

I can see from your pics you are concerned about the excess clearance between the standard half inch bolt shank diameter and the inside diameter of the lower shock mount tube....
Speedway Motors has a stud that has a 5/8" shank diameter...you could grab two and have a local machine shop turn the 5/8" shank down to precisely fit your shock tube inner diameter..

https://www.speedwaymotors.com/Speed...Bolt,5485.html

Or...maybe go to a local auto parts shop and ask for a standard front shock and check the clearance of that lower mount tube on the 1/2" bolt..

It is highly likely the new shock you have has a defective sized inner tube...as these shocks usually take a standard 1/2" grade bolt....

If you find the auto parts store shock also has excessive clearance you may have to either accept the dimension or shim the tube diameter down....

These lower mount tubes are usually a little "loose" when the bolt goes thru. They use a crush style method to lock the tube against the bolt meaning when you tighten the bolt with the washers in place against the tube ends....remember, these are trucks not race cars...

You could use a different style of shock end that uses a Heim (coli over) style spherical bearing instead of the rubber bush style, however, these systems are usually reserved for high performance applications or complex special builds....

As they lack any "cushion" in their action, Heim style ends should be converted to double shear mounting to reduce flex and possible tear out of the bolt thru the A-arm.
