COMP Cams LSr Camshafts

All Out Power for your 5.7-6.2L LS.

No Shortcuts

Unique Grinds

We grind our LSr camshafts specifically for cathedral port heads and specifically for rectangle port.

Make power where you need it

Our LSr family is designed to make power where you need it most. By not selling cams in 'stages' we cater to the needs of the individual.

Desiged Specifically for LS Engines

Takes advantage of the high flow from LS cylinder heads

By recognizing the superior airflow capabilities of the GM LS cylinder head, our engineers developed grinds that are able to move the most air and make the most power.

Broadest Powerband and Most Top-End Power

The LSr series of camshafts feature higher exhaust duration and more lift to provide the broadest powerband and most top-end power of any LS camshaft.

Micro Surface Enhancement for GM LS Cams

The First and Most Advanced

COMP Cams is the first in the automotive aftermarket to employ a new camshaft finish technology for increased strength and performance that far exceeds traditional polishing.

What is MSE?

Micro Surface Enhancement (MSE) is a finishing process that improves the traditional camshaft lobe and load-bearing faces through a 65% reduction in surface peak roughness and provides a 250% improvement in the effective load bearing area.

Spreading the contact area between the roller and cam face allows much higher loads and lower localized stress.

The Best Comes Standard

Through our research and continued efforts, we have raised the bar to the highest level in the LS camshaft performance aftermarket.

Our MSE process is the most advanced on the market. Coupled with our modern lobe profiles your LS will make the most power and spread the surface load to increase long term durability.

No COMParison

Reduces surface peak roughness of freshly ground camshaft by 65%.
250% improvement in effective load bearing area to allow for higher loads.
Uniform pressure reduces waviness for increased durability.
MSE is performed to all COMP Cams LS camshafts.

GM LS Camshaft Types

We often get the question, 'which LS cam type do I need?' Well, that depends.

If you plan to run a three-bolt timing set in a non-vvt vehicle or plan to eliminate VVT, then you want a '54-' prefix camshaft, the left cam in the image to the right.

If your engine is equipped with AFM but not VVT, then look to our 146 or 646 series, the middle cam in the image to the right.

If your engine is equipped with VVT and you plan to retain it, look at our 156, 656, 189 and 689 series camshafts, the right cam in the image to the right.

If you need help identifying the camshaft type in your application, retrieve your vehicle's VIN, call your local dealership to get the engine's RPO then refer to our LS engine application chart.
