[seoservicesus]

Yes. This fits all GM trucks with a 2.5" wide spring.

Using Equation 1, one can determine the area of tensile breakout for each bolt to be 113.10 in² (729.68 cm²), however due to the proximity of the bolts to one another, there is an overlap in projected breakout area. To account for this, one must reduce the projected breakout area by one half of the overlap area when analyzing an individual bolt. The modified projected area for each bolt becomes: more

The nominal shear strength, Bvn, for headed and bent-bar anchor bolts is taken as the smallest of Equation 14, nominal shear strength governed by masonry breakout, Equation 15, nominal shear strength as governed by crushing of the masonry, Equation 16, nominal shear strength as governed by masonry pryout, and Equation 17, nominal shear strength as governed by anchor yielding.

[lilomar]

Similarly, to determine the allowable shear strength, one would typically calculate the shear breakout area for each anchor. For this particular example, given the direction of shear loading and large edge distance, masonry shear breakout will not be the governing failure mode. Calculated strengths for masonry crushing (Equation 7), anchor pryout (Equation 8), and anchor yielding (Equation 9) are as follows:

[laczoka]

Existing masonry codes do not address tolerances for anchor bolt placement. In the absence of such criteria, construction tolerances used for placement of structural reinforcement could be modified for application to anchor bolts. In order to keep the anchor bolts properly aligned during grout placement, templates can be used to hold the bolts within the necessary tolerances. Templates, which are typically made of wood or steel, also prevent grout leakage in cases where anchors protrude from the side of a wall. more

While many of the requirements for anchor design vary between the allowable stress and strength design methods, some provisions are commonly shared between the two design approaches. The following discussion and topics apply to anchors designed by either the allowable stress or strength design methods.

If I read the description right, he removed the bottom plate and leafs 6 and 5, then installed the bottom plate and leaf 6 on top of the stack. Installing two short pieces on top lowers the car by .44" simply due to the displacement of space, but these two pieces will do nothing to support the load. You can achieve the same lowering effect by simply adding a 7/16" thick lowering block between the spring and axle without changing the spring (but use 1/2" longer U-bolts). You now have only 4 leaves supporting the load rather than 6, and there will be almost no center support for leaf #4. more

Beware from the start that this is a lesson in what NOT to do to a leaf spring.

[Galuel]

Since the plates are all same thickness, you have increased the bending load and stress near center of the remaining 4 load bearing leaves by 50%. This is the stress equivalent of putting 450 pounds of added weight in the boot directly over the rear axle. With 50% increase of stress on the spring you should expect a dramatically shortened life for the leaf springs. That is, they might sag an inch after 5 or 10 years (rather than 100 years), and they might break after a few years of use (rather than never in a hundred years). I don't know what else to say other than good luck, and maybe send a follow-up report some years later after you see how it works out in the long run. Maybe you won't live long enough to see it sag, and maybe you won't drive it enough to break a spring, but you could eventually become the DPO in a big way (to the next owner). more

Do not reuse auto or truck Leaf Spring U bolts [links]

[rodrick3nie]

Regardless of the bend type, all Leaf Spring U-bolts are measured in the same manner as shown here. The U-bolt size is given as here

[Bitquux]

U-bolts 9/16" diameter and less are made from 1541 Grade 5 Material. Ubolts 5/8" diameter and greater are made from Grade 8 material. U-bolts have a sufficient amount of rolled threads on each leg.
