    Rated 5 out of 5 by from Old school easy! Way easier to use in an engine bay since you don't need to use a failure prone angle gauge that’s hard to read in a tight engine bay. Faster since it doesn’t have to be zeroed & set up for each bolt. I used these on an aluminum block 6.2 with no issues. Just chase your threads & clean out bolt holes; which should be done anyway.

    Rated 5 out of 5 by from JEGS FTW! No issues with the hardware, used them for my ls2 GTO for having to change my lifters. Came with a paper for the proper torque sequences, and didn’t have to use a torque angle gauge for the final pass. Definitely recommend and if ever needed would definitely buy again

    Rated 1 out of 5 by from Poor quality control Good: -Price -Made in USA? Bad: -Poor quality control : Double the out of round of Made in China bolts -No printed torque specs/instructions provided I noticed bolts were out of round while cleaning and checking threads during pre assembly. Checked with a dial indicator and found they are as much as 0.040" out of round. I checked ARP bolts and it was under 0.012". My set of "made in China" bolts came in under 0.020". I called customer service and they didn't seem to be bothered that they have a quality control issue. Be warned, you get what you pay for!

    Are the provided torque specs for these bolts for a cast iron block only? Looking at the torque specs for iron blocks versus aluminum blocks, all of the torque values seems to be ~10% less for aluminum blocks versus cast iron....

    Asked by: Casey
    Jegs 555-83408 is not a torque to yield bolt, the same sequence/spec should be followed regardless of iron/aluminum
