Forged pistons and rods handle boost pressures stock castings cannot tolerate, while upgraded valve springs prevent float at high RPMs that cause catastrophic contact between valves and pistons destroying engines instantly.

 

Machine work quality determines whether performance parts deliver promised gains or create problems through improper clearances and tolerance stacking. Professional builders with dyno-proven experience justify higher labor costs through reliable results, while DIY attempts without proper tools and knowledge often end badly requiring expensive professional repairs fixing amateur mistakes.

Jeep Internal Engine Parts for Wrangler

From gears to rings, valves, pulleys and dampers, there are hundreds of internal engine components that work together to make your motor run. If even one of them fails, you could find yourself stranded in the middle of nowhere. After towing charges, parts and labor, even minor repairs can end up costing hundreds of dollars. To reduce the risk of a breakdown, it is always a good idea to examine basic internal engine components before you take your Jeep Wrangler on a challenging off-road trail. If there is any visible sign of wear or distress, the part should be replaced before you venture into the great outdoors.
