        5 2001 Cobra - SchuylerP

        Fit great

        These fit perfectly for my mid 01 cobra. The 156-5001 arp bolts were too small and these were just what I need since my block is a later aluminum block. If you have a mid 01 cobra after 06-01-01 these should work for you.

        5 2002 GT - 02gt2v

        always high quality.

        I've never had a problem with arp hardware. I've used this side bolt kit and the main bearing caps showed no signs of cap walk when I disassembled the engine for more upgrades. Plus they are reusable!!

      Will these bolts work on a 2011 gt

      • These will not work on a 2011 GT Mustang as these are for the 4.6L engine. The 2011 GT Mustangs have the 5.0L engine which is a completely different size.

      Is this best for 'light' power adder solutions ? I've heard that the stock cylinder head screws can get stretched when supercharged. Would this assist with strengthening the heads for low boost or lower HP power adder solutions ?150 HP or less for example?)

      • These bolts would be a good addition for low boost applications.
