Isky Racing Cams Releases New Solid Roller Bushing Risers

The SEMA Show is an event we look forward to every year. Last year was the very first virtual release, and it was a welcome distraction from all the craziness of 2020. Still, we were more than excited to return to the Las Vegas Convention Center and get back to our regular lineup – where the he entire automotive aftermarket comes together to showcase their products and the world-class builds they produce.

This year we caught up with a number of manufacturers, but the one that really stood out to us was Isky Racing. As always, the brand’s stand did not disappoint. We caught up with Isky Racing’s Nolan Jamora and got a taste of everything new at Isky Racing Cams.

Using a bushing instead of needle bearings is a big deal for anyone serious about power supply security!

We asked Nolan what they had for the street guys and gals back home. “So the new thing we have for the street guys is a new hydraulic lifter. Johnson does the internals and we produce a ring on them. They’re great for anything that has turbos, supercharger, boost or something like that. They allow you to run a lot more spring pressure. Plus they don’t wear out and last about four times longer. There are no needle bearings here, because it’s “is what fails in the factory pushers. It’s just extra protection. If you’re using any type of power-adder, these are a must. There’s just too much pressure on the riser … »

This cross section of Isky’s new socket lifter shows how much more advanced they are than the original needle bearing lifters.

Luckily for us, Nolan clarified what he meant by all of this. “For example, when people create thrust and create two-stage spring pressure, every component in the engine is subjected to a hellish amount of vibrational energy. As such, harmonics can force oil out of the cheaper tappets.What happens is that the oil escapes through side passages, which may be the result of a rushed machining process – waves and ripples machined into the side of the tappet In factory testing these waves catch the piston, but as it wears those high spots don’t catch it anymore and if you have a higher spring pressure to start with it wears a lot more quickly.

But what’s so bad about needle roller bearings? Well, when the needle bearings separate, they go through the whole engine – the oil pan, the pistons, everywhere. “Basically, this option only costs a few hundred dollars, so it’s a no-brainer upgrade. They will really limit the damage to an engine in the event of a catastrophic component failure. Say you break a valve spring or tip, it will start bouncing and there’s no way it won’t, but this upgrade will limit the damage to the lifter and lobe. So you can just replace that broken component and not have to take the whole engine apart to replace the tappets, rods and pistons.

This close-up of the bushing type tappets versus the close-up of the needle bearing really shows the superiority and relative sturdiness of the upgrade.

These new socket lifters mean more than just cheap insurance, you can also expect extra performance. A needle becomes oblong and only rolls over one or two needles at a time as it rolls, but that bushing rolls on hydraulic fluid, so you have 350% more load capacity, and that’s why the train valves is more stable. So going up the ramp you can be more aggressive as well as going down. It makes a huge difference. Ours came out about four or five years before everyone else on the market, and everyone copied it.

They are available for SBC, BBC, all retrofits (LS, LT), SBF, BBF, SBC and BBC and Gen-III Hemi. So if you’re looking for a simple upgrade that will save you thousands of dollars in potential engine repairs, check out
