What Does This Do?
The Stage 2 cam is a step up from the Stage 1 — more lift and duration for significantly more power through the mid-range and top end. The exhaust duration is slightly longer than intake (228/232 at .050"), which helps scavenge exhaust gases for better breathing. Benefits: 30-45 HP gain over stock (with supporting mods and tune), aggressive lopey idle that sounds incredible, and the power band shifts upward for stronger pull from 3,500 RPM to redline. Trade-offs: the idle quality is rough enough that the car may not pass emissions in some states. MPG will drop 2-3 MPG. The engine vibrates noticeably at idle — if this is your daily driver and your partner will be riding in it, seriously consider the milder Stage 1. This cam REQUIRES upgraded valve springs, non-MDS lifters, pushrods, VVT limiter, and a custom tune. Budget $3,000-4,000 total for the full cam package installed. This is not a standalone mod — it's a system upgrade that transforms the character of the engine.
Required Supporting Parts
This camshaft requires additional parts for safe installation. Installing without these can cause serious engine damage.
Aftermarket camshafts REQUIRE upgraded valve springs and non-MDS lifters. Stock valve springs will cause valve float (valves bounce open at high RPM), leading to catastrophic engine damage. Non-MDS lifters are required on automatic transmission HEMIs because the factory MDS lifters are incompatible with aftermarket cam profiles.
VVT limiter and MDS delete are REQUIRED with aftermarket camshafts on 2009+ HEMIs. The VVT cam phaser will cause erratic timing with an aftermarket cam, and MDS oil passages must be sealed after removing MDS lifters. Without these, expect oil pressure loss and engine damage.
A custom ECU tune is REQUIRED with any aftermarket camshaft. The factory tune's fuel maps, timing tables, and idle control are calibrated for the stock cam — an aftermarket cam changes everything. The engine will not idle properly, will run rich or lean, and will not make optimal power without a tune.
Hardened pushrods are strongly recommended with aftermarket camshafts. Stock pushrods can flex under aggressive cam profiles, causing inconsistent valve timing. Most cam manufacturers recommend chromoly pushrods as part of a cam package.
Tune Required
This part requires an ECU tune to function correctly. Without a tune, the engine computer won't adjust for the new part, potentially causing poor performance, check engine lights, or engine damage.
Technical Details
