How well do stock rockers do with 130# springs?

**gbgn1** · 09-09-2016

Do the stock 3800 rockers have any issues breaking with high lift springs?
Thankyou

If I'm going high lift, I want rollers regardless of the performance of stock as it won't match rollers. But that's just my old school brain saying that, lol.

Don't remember seeing, reading or hearing any issue with stock rockers failing as you ask. I do remember a thread listing the weights of stock -vs- billet Aluminum Rollers, but you'd have to search for that. Valve Spring Binding would probably be a bigger issue imo.

I have 130 lb springs with stock rockers. no issues so far, and I have had them on for about a year with plenty of abuse. I would expect something else to fail before the rocker.
