Question Rear lower control arm & panhard rod bolt/ nut size

hello,

I'm looking to replace my rear lower control arms and panhard rod for better handling. I know that I'll need new hardware, already had to replace one of the bolt/nuts on the panhard rod.

Need to know the size of the bolts / nuts for the rear lower control arms. I have came across the Spohn set you can buy, but would like to save some cash and upgrade the quality of the hardware.

As for the panhard rod. I'm guessing I need another set of these:

GM 11516933
GM 11515744


Thanks

Re: Rear lower control arm & panhard rod bolt/ nut size

If you look at the prices for the bolt and nut that you listed, you will be paying almost $4.00 for one nut and one bolt. Assuming the prices are similar for the LCA nuts and bolts, you would pay about $16. That's $4 more than the Spohn price, and it's top grade metric parts, plus the washers.

Quote:

4) 12mm Grade 10.9 bolts (silver zinc plated)

(4) 12mm flanged head steel lock nuts (silver zinc plated)

(4) 12mm flat washers (silver zinc plated)

You can't buy higher quality than that.

I know there's shipping involved, but how much are you possibly going to save by hunting around a hardware store for parts that may even be Chinese counterfeits?

Re: Rear lower control arm & panhard rod bolt/ nut size

Thanks for the prompt reply!

I guess I will go with the UMI set which is just a shade cheaper!

Now it's time to find out how hard the shop will hit me for installation & alignment. :/


Thanks!

Re: Rear lower control arm & panhard rod bolt/ nut size

Why would you need alignment? Unless you use aftermarket adjustable LCA's there is nothing to align. Even if they are adjustable, you would set them at the same length as the stock bar. Only subframe damage would cause a thrust angle problem. The install is also very easy to do yourself. That's where you can save money.

Re: Rear lower control arm & panhard rod bolt/ nut size

Well, I usually like to do the work myself but no longer have a garage to work in. Can't work on it in the apartment complex parking lot, so I'm subjected to rolling the dice with a local shop. It sucks.

Although I do like UMI stuff, the lock nuts in their kit are inferior to the Spohn kit. UMI uses nylon lock nuts (which I would never put under the car) vs a prevailing torque nut which Spohn uses.

Up to you.
