[68GMCCustom]

Yes, 9.5" 14 bolt. And its holding up to what guys are throwing at it....taking the stock LS2 to bigger cubes and boosting with forced induction or N2O. The 4L70E "Super Duty" trans has been the weakest link. Our TBSS had nothing but a tune....and is on its 2nd trans so to speak as they rebuilt the original at around 25k mi.? The tunes been out now for a while, and won't go back in until I'm ready to start upgrading parts...which will be within the next 12 mths or so. Its out of warranty this month...and paid off in 12. Then the wife gets something new...and I get the TBSS to add to my "collection of 2"...a '68 and an '06...though I'm working to get my dads old white w/red leather '84 Caddy Fleetwood Brougham to add also. Then I'll have 3 and it will be time to move to a home with more garage/land around it!


***BTW - this also makes TBSS's prime candidates to purchase a salvage truck for the complete LS2/4L70e/9.5" 14bolt drivetrain. Actually, I think the complete chassis is used on the AD series (47-54/55?) trucks/SUVs.
