PRW Pro & Elite Series rockers
There’s been a lot of buzz and questions about PRW Pro & Elite Series rockers on social media, so I thought i'd share my experience
First question:
Do they work with the BTR LS shaft rocker kit?
Yes, they do work with the Brian Tooley Racing (BTR) shaft rocker kits.
That said, there are a couple things you need to know before installing them:
• Reuse the PRW trunnion bearing.
The PRW trunnion has the oiling hole for the direct oiling system. If you don’t reuse it, you lose that feature.
• Check your geometry.
Geometry may need adjustment depending on your setup. For example, on a Frankenstein Engine Dynamics M115 cylinder head, I found the BTR stand needed about .050” milled to get the sweep pattern where I wanted it.
Every combo is different — always verify your sweep.
Next big question:
Does the direct oiling actually work? Is oil really flowing to the roller tip and spring, or is it a hoax?
Yes, it works.
During cranking, you can clearly see oil flowing through the trunnion and out the front oiling holes to the roller tip area.
Having direct oiling should help extend:
• Valve spring life
• Retainer life
• Valve tip life
Especially when combined with a roller tip design.
Application details:
LS2 6.0LS
Frankenstein M115 240CC PAC valve springs
1.750 IH at 212#
559# @ open
BAM solid roller lifter
Cam motion camshaft 8620
BTR/PRW LS1 Shaft rocker
If anyone has more questions or wants to see them running, let me know. I’m happy to share more info.

I Googled these and the very first hit claimed needle bearing trunions and needle bearing tips. Back in the day, I saw a few cheaper roller tip rockers that claimed to have roller bearing tips. I ground the end off of the axle on several and they were all identical, none had true roller bearings, they were just round stock with a hole through them for the axle. With the amount of pressure on the rocker tip, I'd hate to think what needles of that size could do to the internals of an engine. Consider that Jesel, T&D, Crower and others DO NOT claim needle roller tips.
Even if these Chinesium rockers have them, it's a bad idea, period.
