Our new Powerstorm 5 piece billet steel cross-bolted main cap set allows you to upgrade the strength of your 5.7, 6.1, 6.2, or 6.4 HEMI block. The introduction of the Hellcat line of SRT vehicles has caused a surge of big power HEMI builds, but one area has always been a hindrance when building these engines; their production main caps. Unable to handle the levels of power the engines can reach, we went to work on a solution. To address this issue, our engineers designed 1044 billet steel main caps. Similar in shape to the factory main caps, they offer a tremendous improvement in durability and strength. These main caps are a wise upgrade in all HEMI engine builds, but are a requirement for those targeting above the 1000HP range.
