Forged Spring Perches

January 16, 2012
Perches are fine, but the nylock nut is useless. It needs to be tapered like OEM nut. Had to order nuts from other vendor. WHY?
No, I would not recommend this product.

very nice

September 21, 2010
these are very nice, BUT, these need to be beveled on both ends. Only the top is beveled, they need to send 2 beveled washers with this, to make it complete. Other than that, they are nice.
No, I would not recommend this product.

Why is there no key way in the spring perch to match the lower shock mount key way such as part # 910-36105 I purchased a front end kit back in early 2013. I am now working on shocks for my 1932 ford pickup. I called speedway back in mid 2013 when I installed the kit and asked about this issue. The tech told me you weld the two parts together. Ok I'm new to this back then, I dropped the issue. I have learned a lot sense then. It just doesn't make sense to have keyed and not the other.

These spring perches do not always get used with those lower shock mounts, additionally the clocking of the keyway necessary for each application can vary. For those reason there is not a keyway cut into these perches. You can certainly have a machine shop cut the keyway into it for you. Many people will have that done when using with the lower shock mounts such as 91036105. The other option is to weld the shock mount like suggested previously.

Trying to use this on a 2 inch wide spring will not work with these perches because the nylon bushing will not set flat to the perch and brake out the bushings. It doesn’t even work if putting a spacer on each side because the body of the perch needs to take the load this would steel let the shackle teeter and work on the bushings.
