    Do yall use regular or mid grade gas in the 5.3?

    I run 85 octane. Here in Utah that is our "regular" gas. The altitude is higher here which compensates for the lower octane. I have 230k miles on my suburban. Never had a problem with 85. Of course once you get down to lower altitudes they don't even sell 85 so then I just run whatever the...

    Diff drop compatibility.

    I'm trying to find some diff drop spacers for my suburban to help correct cv angles. Does anyone know if the ones sold for the silverados/Sierras will work?

    2015 Yukon Denali XL Towing Mirrors

    I put the Trail ridge's on my suburban. I wish they had the turn signal on the glass like the boost auto. I wish they were power but other than that everything works. Lane assist, puddle lights, heated, memory. I REALLY like the spot lights when backing up though!

    "Service Brake Assist" message as well as weird anti-lock brake issue

    Awesome, thanks for the advice everyone. I’ll be replacing that pump soon. Looks like a PITA to get to but I’ll make it work

    Installed bilstein 5100s and rear Z71 springs

    Hmmm, I didn't realize the z71 spring was longer...this has me thinking. I may switch out my springs. I have a 3 or 3 1/2 inch puck in the back and then a puck in the front that lifts it 3" but my front is just a little higher than my rear end (probably like 1/2 to 1") I bet if I put these...

    "Service Brake Assist" message as well as weird anti-lock brake issue

    Called the dealer, looks like it was done 4 days before I bought the truck back in 2022. So they last about 70k miles it looks like lol so I'm on my own with that. I'll look into the scanner. Thanks.

    "Service Brake Assist" message as well as weird anti-lock brake issue

    Gotcha. Any advice on a good scanner that isn't too expensive? I just have a cheap harbor freight bluetooth one that only reads codes but I dont think it will do diagnostic info

    "Service Brake Assist" message as well as weird anti-lock brake issue

    I'm not sure but I'm past the 150,000 mile limit that it references and its a 2015 so also past the age limit. So it looks like I need to replace the pump and belt. Would that cause my Anti-lock brake issue too?

    "Service Brake Assist" message as well as weird anti-lock brake issue

    So I having a couple of odd braking issues. This weekend I was braking hard to avoid sliding down a steep snow covered road. My Anti-lock brakes kicked on but I was not able to actually stop. I ended up putting the ebrake on and that was able to stop me. While braking I got a message that said...

    Gear swap compatibility with Silverado?

    Definitely tows heavy and works hard. I tow a 30 ft camper with it about 7 or 8 times a year. Two side by sides on a trailer probably 10 times a year and then a 19 ft boat probably 15 times a year. Then I take it hunting and take it places I really probably shouldn’t if I don’t have my sxs with...

    Gear swap compatibility with Silverado?

    Luckily I have a mechanic friend that owes me a favor and is doing the install for me! So I just have to pay for parts. My Dad paid $3200 dollars to get his front and back done in 4:10s. So it definitely won’t cost me that much. I’m definitely gonna go 4:10 though since I’m gonna have to buy new...

    Gear swap compatibility with Silverado?

    Yeah if I’m gonna buy new ones I’m definitely going 4:10 on front and back. That’s what my Dad put in his and they really woke it up on the low end.

    Gear swap compatibility with Silverado?

    Well dang. At least the front will work and I’ll just have to buy the back. Thanks for the insight! I really appreciate it!

    Gear swap compatibility with Silverado?

    I’m considering throwing at least a rear locker in at the same time since I will already have it apart

    Gear swap compatibility with Silverado?

    If they will fit I have a hyper tech that I can change the gear ratio with.

    @swathdiver He has a 2006 Silverado with the 4.8l. Mine is 2015 suburban with the 5.3

    Gear swap compatibility with Silverado?

    My father just got his Silverado front and rear end re-geared from 3:42 to 4:10 and he gave me his old parts. My suburban has the 3:08 gears. Does anyone know if the gears he gave me are compatible with my truck?

    Struts with lift? Or OEM size with spacer?

    I’m going to go the lifted strut direction and not coils. I’ve gotta stop spending money on hunting so that I can get them replaced. Every time I take my truck out hunting the struts scream at me and remind me that they would rather be dead then spend another second attached to my truck.

    High Mileage tahoes/yukons/suburbans

    Post how many miles your trucks have?…my 2015 suburban just hit 222,222k miles. It has had a few things I had to fix but it runs like new.

    Struts with lift? Or OEM size with spacer?

    Good to know. I’ll probably just stick with struts then

    Struts with lift? Or OEM size with spacer?

    Do you mean they change back to the struts after trying coilovers? Or keep the coilovers after switching?

    Struts with lift? Or OEM size with spacer?

    Thanks for the advice! That gives me a lot to look at. I had no idea you could replace the front struts with coilovers.

    Temperature of stock thermostat?

    I think the issue I had was due to the fact that my coolant concentration was too high. I have the 208 thermostat. Drained the coolant and replaced it with a 50/50 mixture and it has been perfect since. One of the times I changed the thermostat I must have accidentally put concentrate in and not...

    Transmission temp?

    Trans cooler is the way to go. I paid like 90$ for mine at oreilly’s and it was super easy to install. Pulled a 6500 lb trailer on a 6 hour drive and trans temps never got above 187 in the 98 degree weather. I also have a sure cool transmission bypass and the standard 208 engine thermostat...
