I hope this will be ok with the admins but I wanted to find a thread JUST for members RPO codes instead of just several posts scattered on the site.
I know it will make lengthy posts but that should be ok. I am very interested in this and interested in the discussion it will create by doing this.
Again, I hope this is ok.

I will start with mine, then you post your codes. Also post what Year, make and model of third gen, and any other pertinent info about it and if your original owner or not. Post any pics of your car or RPO sticker as well but please try your best to keep the thread on topic. Here goes Mine:

Mine is a 1985 Z28. My family is second owner to the car.

1HV is the Iroc RPO. My trans am has the speedo delete RPOs also (E5Z E9Z).

~Matt

osso12

im a dumb butt

osso12

Twin Turbo, do you know if you ordered both of these ratios for your cars or where they that way when you got the car?

Neet to see the different ratios between the two years.
My 85 shows the GU4 AXLE REAR, 3.08 RATIO and its a Z, but not IROC Z..
Who is the rear end expert around here? What was factory standard Option for BOTH IROC Z and Z 28 for rear end gears? I did not find a whole lot of info about in my white book and Yes I at least looked. LOL!
Anyone?

80schild

iTrader: (5)

What does "speedometer delete" mean? Maybe it means without digital dash?

Twin_Turbo

iTrader: (25)

Bought the cars used, not new. Don't know what was ordered. My cars have 9 bolt rears, not 10 bolts. J65s too, both of them. The 88 lists G92: AXLE REAR RATIO, PERFORMANCE but I think the 87 has that too but it simply didn't appear in the RPO codes in 87. 87 is a weird year when it comes to certain RPOs

scottmoyer

Huh

1HV is not the IROC-Z RPO. In 1985-1987, the IROC-Z RPO was B4Z, in 1988-1990, it was Z28.

osso12

I'm pretty sure that they are all 9 bolts...Not 10..
But I stand to be corrected.

osso12

E5Z: SPEEDOMETER ADAPTER (DELETE)
E7Z: KEY, SPEEDOMETER (DELETE)
E9Z: SPEEDOMETER KEY (DELETE)

Im trying to get someone to answer that too.
Are these E5Z: SPEEDOMETER ADAPTER (DELETE)
E7Z: KEY, SPEEDOMETER (DELETE)
E9Z: SPEEDOMETER KEY (DELETE)
standard Options too? Are we talking only Z28's or Camaros and firebirds' too?
Ill gander at the white board and do some searching on this site as well. I willing to bet it has been brought up before now.

Iroctopless

Did you look in the Thirdgen Camaro Tech Data section under "1985 Chevrolet Camaro Drivetrain List"?
https://www.thirdgen.org/1985-chevy-camaro

osso12

Thanks IROCTOPLESS! Actually yes I have seen that page. I must have been looking at engine data only as I did not recall seeing the axle ratios.. thanks again.

Iroctopless

No problem.

Regarding RPO codes E5Z, E7Z & E9Z . . . my '89 IrocZ has them all as well.

PS . . . some other sites list those as . . .
E5Z Speedometer Gears Less Adapter
E9Y Vehicle Speed Sensor
E9Z Speedo Gears Less Keys
Still not a great help.

PS;PS . . . over at "Oldpower.com" a post describes it as such . . . E5Z- LESS SPEEDO ADAPTOR. Exactly that. You needed no speedo correction adapter box to make the speedo work properly. Most have no speed sensor either, which is E7Z.

86TA4SALE

Sorry, I'll be more specific. 1HV is the components of the IROC-Z package.

My Trans Am has only E5Z and E9Z so I assume I have a speed sensor because I don't have E7Z.

~Matt

osso12

I wonder if these are nothing more than certain size teeth gears that drive the speedo cable in the tranny housing? Maybe they need different gears for cars with different rear end gear ratios? Something to due with cruise control as well? Is that logical thinking? lol

osso12

If that is true for 1HV, how can 80schild have the 1HV RPO if he owns a 87 GTA?
Somethings not right. I meant to ask this before now but I missed it somehow.
(Notice my dumb butt thread I edited) I still stand to be a dumb but! LOL!

osso12

Here is the answer to the mystery.. I think anway..

For 87 GTA 1HV is ALSO : COMPONENTS OF WS4 TRANS AM OPTION.

I am still looking for Y19 for 80schild 87 GTA...

osso12

Im gonna go out on a limb here and see how close I can get..

80schild, not knowing anything about your 87 GTA, is it by chance either factory silver or have/had silver ground effects/Mouldings?

86TA4SALE

All GTAs had body colored moldings.
1HV must be an equipment code for the items that IROCs and WS4 Trans Ams have in common.

~Matt

80schild

iTrader: (5)

No, it's all Flame Red Metallic (74U) with Carmine Red interior (72D).

For some reason the decoder shows 74U as 'Victory Red'.

osso12

Then I have no idea then.

Y19 for 66-72 olds is Molding, Body Side Lower
for 76-81 Firebird it is MOLDING,BODY SI LWR.
So, I doubt it has actually changed that much since it probably pertains to some type of molding. I misread the interpretation of SILWR to be silver, so thats why I asked about color. Anyone find anything else on Y19 for his GTA?

Iroctopless

Works for me.

As for my '89 IrocZ, it has neither RPO 1HV (or possibly IHV should it have been misread). Maybe it applies to older IrocZ's when RPO B4Z was needed due to the seperate Z28.

JamesC

iTrader: (5)

No 1HV in my 85 B4Z.

JamesC

osso12

Im thinking 1HV is going to show up more in third gen trans am's and maybe just a few IROCS....

Third Gen TA's... Please post your RPO CODES!

There are a couple mystery codes in here. At least to me, anyway. For some reason there is U75 power antenna and V73 fixed antenna. Another is 86A stripe color red/gunmetal. The car is white with med. dark gray interior and gray leather seats, so I don't know where the red comes into play.

86TA4SALE

My 86 Trans Am doesn't have 1HV, however it is also not a WS6. The 1HV may include something like the WS6 sway bars or shocks and struts. I have U75 and V73 as well. My RPOs:

I think 87 is the last year for the 1HV on the iroc, all 88+ Z28s are irocs and as such no distinction. My 87 has it, 88 doesn't. Both are IROC-Zs

86TA4SALE

JamesC has an 85 IROC with no 1HV.

~Matt

mr396

Here is my 85 IROC with out 1HV.

osso12

I think it is odd we have not seen the 1HV actually listed on anyone's IROC-Z
and only on 1 Trans Am.....and what the heck does it actually physically pertain to anyway? No one has said.. My guess its a sway bar or something similar on suspension.
Lest I missed something.....

Twin_Turbo

iTrader: (25)

I have it on my 87 B4Z on it too

osso12

Thanks, I did not see it before. Sure enough is there.

Look up posts that have my buildsheet on it. It shows 1HV and then says B4Z for the description. Whatever that is supposed to mean!!

yo soy el warg

Twin_Turbo, your 1988 Iroc doesn't have B84 or B9K? So you don't have the body side protective moldings on the front fender,door, and back quarter panels? This is really unusual for a 1988 Iroc. I haven't seen any without these on 1988 Irocs. I have on earlier years.

No, no side moldings on this car.




It's an unusual car altogether, look at the RPO list, it has a lot of deletes and all of the performance options yet it's not a 1LE. It only has power windows, no power mirrors, no power locks, no power seats, no AC..it's bare bones. Has 5 speed, LB9 high output (5500 redline), 9 bolt axle w/ perf ratio, J65 discs.

Look at the redline and metric gauges, even the oil pressure is in Kilo Pacals. odo is km not miles.


This is a weird car and it's in pristine condition with onl 50K on the odo. It's completely original and unmolested. The only issue is the exhaust is shot so I'm replacing it with the stainless edelbrock system that came off the 87 and keeping the stock tip sections.

T-FATTY

Osso12 thanks for the break down on rpo codes. I thought this find was a cool one - 91 Z28 conv. 5 speed.

You have the metric gauges because the RPOs show X06 and Z49. It was a Canadian car.

I know it's a Canada export car, I bought it from the 1st owner who was a pilot for a Canadian Airline. I posted the pic because of the tach redline
