Serious Cams for Serious Performance. If you're looking for a high lift camshaft for a highly modified street Mustang, these Comp Cams Stage 2 XFI VSR Camshafts are your answer. This serious street cam delivers big gains on highly modified cars with a noticeable idle. May not be street legal in all areas, please check your local laws.

Big Gains for Modified Engines. We've heard of 30+ horsepower on modified vehicles with these cams. For these monster cams, you'll need new springs and get the best results with 3.90 rear gears and a 3000 stall speed torque converter.

Compatibility. These camshafts are designed for the 2005-2010 4.6 and 5.4 Modular three valve V8 Mustangs. These cams require a spring upgrade and tuning is recommended.

Tech Notes:

Note: Want less extreme cams? Consider Comp Cams' Stage 1 cams. Got gears & converter but don't want to buy springs? Check out the NSR cams.

Technical Note. The installation of these Comp Cams will require a phaser limiter kit and custom ECU programming.
