Anyone knows if they come that way from factory ??

labrat

Iroc's did, my 85 Z28 didn't, not sure about firebirds.

MdFormula350

my 88 iroc-z had wheel locks, my 88 formula 350 had them and my 91 formula 350 has them also.

Z28DJP1987

Came standard with the 16" IROC wheels on my 1987.

GreenRS

My 92 came with a set.

Good question Sammy. The Camaro White Book does not list wheel locks as an option for any third generation year, so I can only surmise they were standard equipment. But I cannot begin to guess whether this is true for all years / all wheels. I feel a survey is in order. So here is what I know to be fact:

RPO PB4 = Wheel Locks
Both my 1987 Z28 convertible (15" wheels) and 1987 IROC-Z (16" wheels) have PB4 listed. Contained in my documents with my convertible, i.e. Owners Manual, Convertible Top Supplement, & Warranty & Owner Assistance Information, was the attached pic. Although it shows a Firebird wheel (with nylon nut caps), it does state, "Actual wheel may differ from illustration."

The short easy answer is... YES!

So far the following cars I've had first hand experience with had wheel locks.

85 Trans Am (15" wheels)
88 Camaro Coupe
91 Firebird 3.1L
91 Firebird 3.1L
91 Formula
91 Camaro RS (16" wheels)

Etc... I'd have to say they're pretty common. There are two varieties, the first style are black steel capped lugnuts that match the 82-87 Camaro lugnuts. The second are threaded gold colored nuts that match the 88-92 Lugnuts. The current threaded lugnuts are pretty similar to the thirdgen locking lugs, but the threads tend to be longer.

A little more info...

The lugnuts came in a plastic bag with a card similar to the page Willie posted, depicting the 84-87 16" Trans Am/Formula wheels, the actual lugnuts, the key, and a sheet of labels with the information for ordering new lugnuts. The sheet was perforated with 3 cards, one was adhesive backed to be applied in the console, one was for the owners manual or owners wallet... not sure what the third was for.
The factory lugs were manufactured by Amcor.

Both my 85 and 86 TA, the locks were not put on at the factory, they were added at the dealer with added cost. They are exactly like the locks I have seen on other thirdgens.

irocbarry

anybody wanna post a pic of them

im confused on what your talking about

None of my cars have had PB4. In fact when I got my 82 T/A, it came with an *aftermarket* locking lugnut set that a previous owner bought because I guess he wanted it and the car didn't come with it from the factory. I have the 20 original lugnuts in a little plastic bag. My cars are listed below in my sig, plus an old 83 S/E I once had. None of the 4 had it.

I should also point out that I have all the locking lug stuff from my convertible. Most of it was still in the bag with the cards and the key. I have another set of the paperwork I took from an 89RS with 15" wheels, and another set from an 88 Grand Am. Its all part of my documentation library.

breathment

no wheel locks for my 88 GTA.... i need to get some though

Freeze

my 1992 firebird came with wheel locks

Randy82WS7

ive got an 88 bird with 15" alum wheels option and wheel locks all listed on buildsheet

90TA

PB4 was an available option on 3rd gens since '82.

My '84 TA has it listed on the RPO label.

Randy82WS7

looked in console of the '88 W62 camaro we just repaired and its got P84 also, and a sticker in there all about how its got high security wheel nut on each wheel and about how to get replacement tool and other info about the locking nuts, just pulled the car out of the garage a bit ago, fuel pump replacement complete, its not a hard job to pull tank out and put back in

good luck

Z28DJP1987

As I said before my IROC came with the locks and I got rid of them. They are a pain in the butt to change the tires with and they don't work. When my car was stolen in 88 they took the wheels and the radio and the locks did not stop them. High Security wheel nuts only for you and not someone who wants your wheels. My opinion.

There are about two million ways to defeat the factory locking lugnuts... but your typical 14 year old with a tire iron is going to give up pretty quickly.

A new set from GM costs $20, having a set removed by a tire store if you lose the key is only $5-15, a set of 16" factory wheels can be hard to find locally and extremely expensive to replace. Its worth it to have the locking lugs, even if its a minor security benefit.

PontiacV8

...my `91 TA (Export - Marketing Area Europe), 16 inch Diamond Spoke came with wheel locks...

Ron84TA

My 84 TA has them matching beauty caps to match the other beauty caps .

4mul8r

Exactly.....That's why we lock our doors as well. Anyone can break into a window if they want to, but it still prevents thefts.

PyRo9862

My 91 RS with 16in rims has them
My 91 RS with 15in rims didn't have them

posbird87

when i bought my 87 formula it still had the factory lug nut locks

1988-1992 Z 28

I have a 1990 iroc with 16" wheels. I know this is a stupid question, but can you tell at a glance if they are installed? All 5 look the same on each wheel. Or is there a plastic cover over each locking lugnut for looks?

OutLaw305

92 rs is a yes

PyRo9862

Go try to take a tire off and find out
I suppose they could have put a cover over the locking nut, but then there would be one over every lugnut to make it look uniform I would imagine. Just go and look, shouldn't be hard to figure out. Most likely you don't have them though if it isn't obvious or if you don't have covers on all the lugs.

1988-1992 Z 28

I just noticed in the diagram that Willie posted that it shows a nylon cover to be removed from the locking nut first. I guess I need to go out and see so I can make sure it has the right tool to take it off if it has them.

82RECAROTA

The lug nut covers (nylon cover) simply unscrew. Should be just hand tightened.

84 Z28 5.0 HO

My 84 Z28 has them.

Anboy have an idea where I can get one of those black nylon lock covers im missing one.
You think a junkyard would have them?

Scania

My 1988 iroc has them.

Nate1

My 88 IROC-Z had them when I bought it but didn't have the "key" for them. I had to beat a socket on to them to get them off, and later I found a sticker on the underside of the rear Bose speaker giving me the serial # of the locks and how to get a replacement "key". I sold the car at Christmas and I still have the lugs.

Chet

My GTA got them. Kinda sucks when you go to the shop to get an alignment and you leave the key at your house...

any parts store should have them.

Willie's pic is of a 16" TA and Formula wheel like my '87 has. They have black nylon caps on all the lug nuts, not just the locking ones. The cap is for looks, not for security, lol.

Yes, mine came from the factory with them. It was an option that I spec'd when I had my car ordered. But you're right. They won't stop most car rapists from getting the wheels if they REALLY want them! But then again, when they've got the entire car, they have plenty of time to work at it!

Bandit400

My friend's '89 RS (15 inch) had them and my '92 (16 inch)has them and my locks worked with his. We found out one day when he had a flat and couldn't find his lock tool. GM stopped putting locks on F-cars at some point duing the 2002 model year and I was not happy about it.

Tranny89

My 88 T/A 16inch Black RIms had them
Also my current 89 T/A black Wheels have them as well
