Kelltrac IRS studs

[K4fxd]

Anyone use these? Would you buy again if you got a different car?

I ordered a set. My IRS assembly needs to come out at least 2 times in the next month. This should prevent stripped threads.

I have a set, install was easy and it's very easy to drop the rear cradle without fear of cross threading!

I made my own by cutting up McMaster all-thread into 10" sections.

They are not high grade steel so I only use them temporarily and then go back to the blue bolts when done.

Total cost is around $50.

Support the cradle with a floor jack, and then remove each blue bolt and replace with the all-thread stud, one corner at a time. Then you can lower the cradle to the level you want, and run up the nuts/washers sets for the final support. Expect to deal with some binding. It may be helpful to use a little oil on the threads.

The next time mine comes down, those go in. They've been out of stock forever. Are they back available?

I ordered a set a year and a half ago. After several months of waiting, Kelly said he was having trouble sourcing a vendor and refunded my money. About 6 months later they popped up in a marketing email from Lethal, but the link did not take you to them and they were nowhere to be found on the website. I emailed Kelly to see if perhaps they had come back in stock, but he never replied. It does appear that they may actually be in stock again at this point.

I hope they are in stock, web site said 2 to 4 weeks for shipping and it accepted my order.

I like the idea of these. But it's costly, and I don't see an option to ship to Canada.
My subframe is going to be lowered down considerably to do the front diff bushings. I'm considering @GTP's method and use some 250mm long 14mm x2 threaded 304 stainless rod I found online. Thread in and remove when done. I'll probably never lower the IRS again unless something else breaks. I'm getting to the point where I'm satisfied with the IRS now and also completely fed up working on it.

304 isn't strong enough to use as actual studs, but using them as guides like GTP is a good idea.

Yeah, I realize 304 is not an equivalent for hardened steel bolts. Stainless so they don't rust sitting on the shelf between uses.

Lethal Peformance has them - they don't ship to Canada ? (they're here on the forum, maybe they'll chime in)

Kell-Trac only accepts US zip codes for shipping options. I tried entering a Canadian postal code and could not proceed. I'm going with the temporary threaded rods if I need to re-align everything.

Have you tried them ?

(don't know if they have just the studs without the inserts but would be worth asking)

 

[S550 Recon]

They must have gotten more in stock, mine arrived the other day. Great mod!

Tracking says I'll have them on the 4th.
