Tahoe PPV Deflector installed on 15 Suburban (shorter lower valance that comes on Police model)

[Danyi2170]

I just installed this on my lowered Suburban. Here is a comparison of the ground clearance from both deflectors.

Stock height and stock air deflector:

7 13/16in. Of clearance at the sides of the deflector. And 9 5/16in. of clearance at the center of the deflector.

Lowered height (2/3 drop) with PPV deflector. 11 11/16in. Of clearance at the sides. And 11 1/2 in. In the middle. It slopes slightly inward towards the middle.

Amazing how much clearance I GAINED with this even though I’m lowered. Win win !!!

I ordered the ppv air dam from GMpartsnow on Thursday and got it this morning (Saturday). Although this part is damn near $400 on its own, I couldn’t pass up the shipping of this site compared to others. $29 vs $290?! I installed it today and love how it looks in addition to the additional clearance.

For once! Usually I am the one asking for help!

Thanks for mentioning this

Just a heads up -
my PPV airdam arrived and looking at it, the bottom edge plastic isn't finished as cleanly as I had hoped it would be for $300

It basically looks like GM just used one of those huge paper cutters and sliced a regular airdam

I regret not buying a extra regular airdam and using extra $200+ to buy the tools I see others in this thread using.

OH WELL

dang man that sucks!

We just finished putting on GM Part # 23365760

It is the Lower Deflector that comes on Tahoe PPV. it is about 1/4 of the length of the stock piece.

It's a small mod but I believe it has changed the look on our suburban quite a lot, we like it.

I got it at, for 281 plus shipping
https://www.gmpartso...lector-23365760

The main reason was to gain ground clearance, for these off-road times, like when parking at a mall to clear curbs

Also already helps on steep driveways and coming out of parking lots...



The removal of the old piece and installation of the new one was quite simple. Remove some bolts/ torque screws, pushing down some clip, partial removal of front wheels liners.



I can't comment on any decrease in MPG on highway, as we use this truck in town.

Did you need any additional hardware to install the new air dam?

Thanks

nope. remove the stock one, put on the other one.
Be Careful to use a clip/retainer removing tool, along with amazon cheap trim removing tools, bunch of tongues of various thickness.
I choose to take mine to a body shop and it took them an hour to take care of it.

 

[Phil Rosche]

Can you point me to the clip/retainer and trim removing tools?

Thanks

 

[Tahoe14]

It looks like a fork with just two prongs. You can do a quick Google search for both items. Harbor Freight carries the trim tools and any automotive store should carry the clip retaining tool.

JUST cut the OEM with a cut off disk still attached to the truck. You guys are crazy to pay 300$ for cut plastic.

Is GM Parts now the best pricing for the PPV air deflector part: 23365760?

Sawzall and a steady hand worked great for me. I agree the cost of this silly thing is utterly laughable.

These guys are nutZ you're gonna pull it of and resell it? No one wants your used tahoe lower plastic piece. Just cut the damn thing!

 

[BeenChevy]

Haha was just reading through some of these. It's really simple to cut the lower air dam while it's on the vehicle. Just roll it up on some ramps and use a dremel. I had put some blue painters tape above where i planned to cut in advance and just free-handed it and it came out great. Don't fear f'ing it up - it'll turn out fine. Just be sure you measure how low you want on each side first and let the dremel walk itself through. no stress. good luck. A guy could also make a very light cut with an xacto or box cutter and gradually cut deeper and easily bend/break it off too. Sand the rough edge with your dremel or by hand after and it'll come out great - have confidence in yourself

 

[theycallmecoyote]

Absolutely agree with that ^ I did it on my Escalade a week or two ago and I was definitely afraid I was gonna eff it up (even though I pride myself as being fairly handy). Came out great. Just measure before you cut and take your time

 

[Phil Rosche]

How much do you all recommend cutting off?

 

[STORMIN08]

what is your preference...i am starting with the lower wings for now, then possibly shortening to the mid way relief line

 

[rjaneway34]

The lower wings keep it off the curbs. That’s plenty enough for me at this point.

 

[STORMIN08]

Here is a reference line right at the top of the lower wing 1.5" / here it is trimmed, literally 20 minutes total time
