Well after my 4.10 gears there is a vibration wall I'd say at 100 mph, I think that would be about the equivalent of 130 with stock gears. It certianly feels like the driveshaft will break if I go faster. I'm going to head to a driveline shop and get it balances, my friend with a Marauder had the same issue at about 120 after his 4.10 gears and it solved the issue.

 

that 110mph is b.s. personally i got mine up to 135mph. even though the gauges only go to 120 the guy i was racing went to 140 and he told me. it gets up there

 

I hope you have a tuner because if not your statement is BS because our cars stock at speed limiters around 115

 

Using a gear calculator, with the stock gears i hit 4200 rpm in 5th gear. I believe it came out to like 139mph or something. The car would not go any faster.

 

Ah, no it isn't BS, the stock speed limiter is set at 113 for all v6's. Unless you have a tuner and it's removed, you can't exceed 113.

 

Man that would be a sh*tty guarantee..."we gurantee our driveshafts to disintegrate and risk you personal injury at 130 MPHS or your Money back!" Yippy! Sounds like a win win to me. LOL sorry had too.
