Been reading past threads about UDP's, & I have two important questions before installation of my UDP's.


(1) Should I purchase new bolts??

(2) How much torque is used when installing UDP's????
 
1) Yes because the stock bolts are TTY
2) I went 90lbs and made a tool to hold the crank to keep it from spinning
you can use an impact wrench just tighten it too
 
What's the part # for the bolt? An ARP part # preferred. I'm doing this install soon also.
 
Ive re-used crank bolts as many as 10 times and never had a problem...save your money
 
Waiting for them to have another bolt shipped. Its times like this......I wish I had the tools, the garage and some time, so i could do it myself. :banghead:
 
I had Chuck Norris hold the bolt with his gaze while I turned the engine over. He had to close his eyes though because it wouldn't turnover... :burnout:

Read post #6 and #8 the TTY bolt broke on the reinstall as it should have.
It's a one time use bolt.

TTY bolts rarely break, they will stretch though.

Ive compared the lengths of new bolts to used bolts and they are near identical.

i hate dealing with broken bolts so i always replace them, not worth it IMO

No not a bolt this big.

Ever seen a modular rod bolt stretch? It can grow an inch if you look at it wrong :eek:
