How long of U-bolts for a 6 inch lift?

Probably 14″ on each side.

Can you reuse U-bolts on trucks?

We get a variety of reactions when we advise our customers that reusing U-bolts is never a good idea. There are some very specific reasons why we stress this point so much, trying to sell you something you don’t need is not one of them. U-bolts are a torque to yield bolt.

What happens if you reuse U-bolts?

Reason 2: Used U-bolts don’t tighten the same as new U-bolts. The next issue with reusing U-bolts has to do with the threads themselves. When being tightened, the threads are deformed under the torque. Each time the U-bolt is tightened the threads are cut and grooved by the nut as the nut is tightened around them.

Do they make Grade 8 U-bolts?

Grade 8 Square U Bolts Grade 8 Square Bend U-Bolt Kits Come With (2) U-Bolts, Deep Nuts And Thick Washers.

How tight should you tighten U-bolts?

Tighten all U-Bolts until they are snug only. Tighten in the sequence shown to approximately 1/3 of recommended torque. Repeat, using the same sequence, gradually increasing the torque through a second and third stage until the recommended final torque is attained.

What is the torque specs for U-bolts?

Recommended U-Bolt Torque for Cold-Formed U-Bolts

Size Material Grade Max. Torque Ft. Lbs. Unplated
1/2 – 20 5 70
9/16 – 18 5 100
5/8 – 18 8 177
3/4 – 16 8 313

What bolt is stronger than Grade 8?

Grade 9 bolts are ideal for heavy-duty applications and are also often used in heavy machinery such as bulldozers. Not only are these bolts considerably stronger than they’re grade 8 counterparts, but they are also considerably more resistant to corrosive elements as they are made with yellow zinc chromate.

What is the difference between Grade 5 and Grade 8 bolts?

Grade 8 bolts have been hardened more than grade 5 bolts. Thus they are stronger and are used in demanding applications such as automotive suspensions. Grade 8 bolts have 6 evenly spaced radial lines on the head. Grade G is roughly equivalent to Grade 8.

Do U-bolts need to be torqued?

Cold-Formed U-Bolts which have been torqued to a set preload are recommended to be re-torqued after a short time to take up the stretch in the set of the material. U-Bolts that have been well lubricated with an anti-seize compound will have a torque range between plated and unplated values.

How much weight can U-bolts hold?

What does 8.8 mean on the head of a bolt?

So, in English, a PC 8.8 bolt is a bolt with a nominal tensile strength of 800 MPa and a nominal yield strength that is 80% of the bolt’s nominal tensile strength, or 640 MPa.
