New LS-Specific Ultra Pro MagnumT Rocker Arms From COMP Cams® Increase Ratio And Stiffness Over Stock Rockers, While Also Increasing Lift Without The Need To Swap Cams

As LS engines continue to grow in popularity, COMP Cams® has expanded its line of rocker arms to build components specific to LS applications. New Ultra Pro MagnumT Rockers are made from investment-cast 8650 chromemoly steel, utilize upgraded trunnions and needle bearings over stock and are stronger, stiffer and more durable than the stock parts. They also feature a 1.8 ratio (compared to the stock rockers' 1.7) and utilize a roller tip instead of a slider. The higher ratio and increased stiffness make these rockers a great option for increasing lift without changing cams. This increased stiffness, along with the upgraded trunnion package and roller wheel, also makes them a perfect choice when running aftermarket valve springs. The rockers are available in a bolt-down design that uses stock rocker stands and in a stud-mount option for customers looking for an adjustable valve train. The stud-mount version is perfect for individuals running mechanical lifters as well. COMP Cams® LS Ultra Pro MangumT Rockers Arms are available for LS1, LS2, LS3, LS6 and LS-based truck engines and come in individual sets or kits featuring studs and guide plates. Kits do not include pushrods, but they are available separately.

  • Increased (1.8) ratio & stiffness make rockers a great option for increasing lift w/o changing cams
  • Investment-cast 8650 chromemoly steel body creates components stronger, stiffer & more durable than stock 
  • Increased stiffness, upgraded trunnion & roller wheel make rockers  perfect for aftermarket valve springs
  • Two designs available - bolt-down using stock rocker stands & and stud-mount for adjustable valve trains
  • Available in individual sets or  kits for  LS1, LS2, LS3, LS6 & LS-based truck applications

Great value, great quality.
Color: Black/Black/ Black Digital
My husband bought this watch for work. He can’t have his phone on him at work so this watch has been very useful for him. He sweats a lot and works in a warehouse. He has a nicer “church” watch I bought him as a wedding gift and he actually has started to prefer this one. There are only two little annoyances (which might be able to be fixed) every hour the clock beeps and that the alarm goes off every morning including weekends. Those things might be features which some desire and some that even we are impressed by so 🤷🏻‍♀️ as I said, those minor issues might be fixed if we look into them but my husband doesn’t find them as bothersome as I do and he’s the one who wears it.

Would definitely recommend this watch.
Color: Black/Black/ Wjite Digital
Nice manly watch. Many Timex watches are too small. I love the size of this one and yet it's still lightweight. The face of the watch is neatly organized and very clear to read. Indiglo light works well at night. Only thing I see missing from this watch is a countdown timer. It has a stopwatch.

Big face, easy to read Timex quality at superior price
Color: Black/Black/ Wjite Digital
Great watch at amazing price. Better looking and much cheaper than current timex ironman models. Large face and numbers = easy to read. Has alarm and stopwatch functionality. Intuitive interface.
