COMP Cams & Lunati LS Rocker Arm Trunion Upgrade
Colorado Speed LS Retro-Fit Rocker Arms, 1.7:1 (GM LS Series)
There’s no denying that the GM LS engine platform has proven itself as a performer. The valve train is no different, with an improved design that makes for a perfect combination of power and durability to complement the impressive cathedral port cylinder head design. The rocker arm design features a lightweight, yet stiff rocker body that is strong enough for most applications. However, when it comes to high performance racing applications, high rpm and high valve spring pressures can put the factory rocker arm’s trunnion under intolerable stress.
Colorado Speed has taken an OEM cast steel replacement rocker arm body and added a captured roller trunnion for use in extreme street and race applications. Perfect for drag and circle track racing applications that mandate the use of stock engine components, this performance rocker arm modification is a “must have” upgrade for your LS factory rocker arms. The captured roller trunnion increases stiffness and durability and is NASCAR proven.
Colorado Speed uses COMP Cams® with a new LS rocker arm retro-fit trunnion kit that replaces the cageless, loose OEM needle bearings and powdered metal trunnion with a premium 8620 steel alloy trunnion and caged roller bearings for added durability. The new design from COMP Cams® utilizes caged roller bearings that greatly reduce the possibility of the bearing failure experienced with stock LS needle bearings, which can send loose needles throughout the engine upon failure.
Colorado Speed LS Retro-Fit Rocker Arms are based off customer supplied core rocker arms. Customers can either supply their OEM rocker arms to us or prepay a core charge and send us their core rocker arms within 30 days for a core charge refund. Each customer supplied core rocker arm is checked in detail and refreshed. Customer supplied core rocker arms must be in useable condition. No core charge refunds will be issued on damaged unuseable customer supplied core rocker arms.
If you are supplying your core rocker arms to Colorado Speed, a representative will contact you on shipment after receiving your order.

NO, you don't need a hydraulic press!! However, a small, bench mounted arbor press works quite well. Yes, you could use a vise, but you'd probably need 3 hands, to keep everything in proper alignment. This isn't a "muscle" job, it's a "finesse" job.....

just got mine in today. with a bench vice it took about 5 mins per rocker. I put the bearings in the freezer for a bit and the entire setup fell together easily.

I am working on this and a valve spring change out.
A word to the wise:
Get yourself an 8mm 6point socket for a 3/8" drive.
A "deep" socket gives more bite then a shallow one.
I (tried) an 8mm 1/4" with a 1/4" to 3/8" adapter and it cracked (the adapter) in half on the first turn (didn't like the torque I guess!).
Was a cheap adapter, but with 16 to do, I bit the bullet and got the right socket for the job.
The bearings are duck soup to remove and a small vise works great for pressing the new bearings in.

It appears that the "Colorado Speed" versions are rockers that have had the conversion kit installed, whereas the "Lunati version" is the parts kit for an "in the field" conversion by the customer...
