Compensator Ramps
I'm wondering if there's a fan favorite with Cycle-Rama vs. Star Racing compensator ramps?
One is 4140 chromoly tool steel and the other is billet EN36 case hardened. I have no idea what that means or what the difference is between the two.

Case hardened means only the outer few millimeters of the surface is actually hardened. 4140 tool steel is very hard, very tough, but also heavy.
Since we're on the subject, anyone ever wonder why the OEM compensator ramps aren't finished? Rough cast on rough cast on parts designed to slip against each other seems stupid.

Finish on compensator ramps.

I'm leaning toward the Cycle-Rama but can't find one in stock anywhere. FuelMoto thinks they're 5 - 6 weeks out. I sure wish these supply chain issues would get straightened out.
The Cycle Rama ramp is constructed from 4140 chromoly, this steel alloy is used in high stress applications such as bearings & races and very commonly with cutting & machine tools (hence the name "tool steel"). The Star Racing ramp is billet EN36 & case hardened, this offers an extremely high tensile strength and is commonly used in components such as gears, connecting rods, and crankshafts. A blanket answer is both the Cycle-Rama an Star Racing comp ramps are equally effective in elimination of ramp failure. We've sold and installed many of each and have encountered zero issues.

Both are very similar but the tensile strength is higher with chromoly.... which is prob why they case harden the en36 Both are tough materials

It depends on who you want to believe, but I've seen enough M8 ramps break that I've decided to be proactive and replace it.
