Can you reuse roller rockers?
Can you reuse roller rockers?
Usually, they are reused anyway even if they are the stock stamped steel rockers. No need to buy new ones.
Can pushrods be reused?
Pushrods are reusable as long as they are not bent. Check your valve train geometry to be sure the length is correct.
Can a roller rocker be replaced with a contoured tip?
However, as the rocker arm ratio increases, angles get sharper, lift gets higher, and the tip has a harder time maintaining the right geometry to last as long. Replacing the contoured tip with a roller compensates for this problem at the cost of more complexity and weight.
What kind of rollers are in factory rockers?
Now let’s talk about the rollers in these rocker arms. Factory rocker arms usually have a fulcrum, or pivot, that’s made up of either stamped steel or a bushing of bronze or Oilite. The tips of most factory rocker arms slide slightly across the valve as they go through their motion.
Can a roller rocker Really improve your performance?
Do roller rockers really improve performance, save gas and make your teeth whiter? Well, it helps if you know how they work, when they’ll work for you, and when they won’t. Let’s separate the poseurs from the rest of us right away.
Can a roller camshaft be used with roller rockers?
In other words, an engine can feature a roller camshaft combined with ball friction rollers, or with roller rockers. Or, an engine might feature roller rockers but not a roller cam. The two don’t necessarily need to be used together.

How does a roller rocker work on a valve?
The valve needs to be pushed down, so the rocker arm works like a teeter-totter to change the upward motion of the pushrod to the downward motion needed to open the valve.
What’s the difference between stock and roller rockers?
The results were predictable—in each case, the engine made more power at high rpm and lost some power in the lower ranges. For our first set of tests with the stock head, we compared stock rocker arms with a 1:1.26 ratio to the 1:1.5 ratio roller rockers. The ratios increased the 0.295 inch of lift to 0.372 inch and 0.446 inch, respectively.
