To prevent costly engine failures from the increased internal loads of high-power tuning, Atomic Conrod and pistons Combo offer critical upgrades before catastrophic damage occurs.

For Ford DOHC engines, power levels of 300-350 RWKW (400-460 HP) on Premium 98 fuel—and slightly higher on E85—put engines at high risk, often leading to broken conrods and ring land damage.
With over 500 Barra rebuilds since 2004, Atomic has seen numerous failures firsthand. The Atomic Engine Rebuild Kits provide options from mild upgrades to 1000+ HP setups, using the same quality components as their record-setting engines, making them ideal for enhancing Ford SOHC/DOHC 6-cylinder engines for substantial power increases.
