So my L83 destroyed a lifter after I did a cam swap at 33k miles. Made it to 88k miles of my right foot on the floor all the time. This L87 is so much smoother and more powerful. I did a DOD plus delete kit, Katech Ported heads, BTR 225 cam plus Ported L86 intake and ported TB. It's a beast smoother and way more linear power and torque than the cammed L83. Yes some of this swap was annoying and a learning curve. If you guys have any questions let me know [email protected] or call text me 813-735-9097 Jack.

Well I'm ok because the marking compound still looked fine on my pattern Thanks for the Concern Sent from my LM-G820 using Tapatalk

Did you put a Truetrac in your truck also?????? Sent from my LM-G820 using Tapatalk

Used same Gear. I didn't have to reset pattern Sent from my LM-G820 using Tapatalk

I installed the Truetrac last night. You have to cut a little bit if the axle retaining thing. I don't know what else to call it. But it must be cut to get it into place past the ring gear. I don't know if that is because I have a 4.10 gear maybe not because my 3.42 gear was the same thickness. I didn't have to use any ring gear adapter going from 3.42 to 4.10 on the stock open differential. So maybe no need to cut this if you have a 3.23 and down numerically just guessing. So besides the Ring Gear adaptor and cutting the axle button gizmo it is a very straightforward Install. Set your Backlash from .006 to 010 add Fluid and drive it. Synthetic Fluid and additive Not Needed or reccomend. It Rips from a stop now. I can feel the whole truck kinda lift and launch now. I'll post more after I drive it a few Weeks. If you guys have anymore questions about the install just message me. Sent from my LM-G820 using Tapatalk

I'm doing mine this weekend. My Truck is a 2015 5.3 1500. I already did the 3.42 to a 4.10. I installed that over a year ago. Sick of the open rear. Been going back and forth between the Yukon 9.5 Clutch style POSI. The Yukon is a direct swap now. No ring gear spacer needed. But I decided on the Truetrac and ring gear spacer. Stronger, no clutches to wear out. No additive needed. Just high quality non synthetic gear oil. Sent from my LM-G820 using Tapatalk

2100 sounds about right. Or just do it yourself and have it towed in for the tune. That's what I did. I did my Cam and stall converter. Then towed it to shop for the Custom Tune

I changed my Driveshaft to a 2 piece high performance shaft and I changed my Axles shafts. I am now Vibration Free Sent from my Pixel using Tapatalk

Or you could design a J pipe or 1/4 resonator and have no drone like me. I have Long tube Headers, stage 3 TSP Cam and no cats and 3 inch exhaust all the way out. I have zero drone after designing my J pipe resonator
