kyb shocks/ part numbers
 

Anyone using kyb gas a just shocks on a 4-6 or greater drop. I had them on another truck, and want to put them on again, but can't get kyb to help me out with length specs etc.. I guess they won't publish the info I need to look them up that way. So if any one has them and knows part numbers I would really appreciate it. Thanks Jared

Re: kyb shocks/ part numbers
 

Lets see if you get a better response in the Suspension forum.

Re: kyb shocks/ part numbers
 

If someone has this information and posts it, are the shocks going to be different for a 67-72 setup vs. a 73-87?

If so... can someone also post up the parts numbers for the 67-72 KYB drop shocks.

Thanks in advance!

And, I hope that I didn't hijack your thread jared78; this is a question I've been meaning to ask but always seemed to forget. :rolleyes:

Re: kyb shocks/ part numbers
 

no all the shocks are all the same. i prefer doetsch tech shocks for lowered trucks. although i have KYB's on my Caprice and i love them. KYB's just dont work well in the rear of trucks because trucks are so light. thats my 2 cents on shocks

Re: kyb shocks/ part numbers
 

bump for KYB parts numbers...

Re: kyb shocks/ part numbers
 

This what ECE just sent me for my 2/4 drop on a 70. Hope it helps.

Re: kyb shocks/ part numbers
 

Thanks Jim!

bump to make sure the numbers pictured above will work for jared78.

Re: kyb shocks/ part numbers
 

btw my actual drop is more like a 4.5/6 but they based the shocks on the springs which where 2/4

Re: kyb shocks/ part numbers
 

Are those ECE numbers or KYB numbers?
It looks like you can read a different number thru that sticker.
(in the lower RH corner)

Re: kyb shocks/ part numbers
 

Good call lolife.

The 7510 number crosses to KYB #344055
The 7502 number crosess to KYB #344068

Re: kyb shocks/ part numbers
 

Excellent, I was just about to come over here and post that the number didn't correspond.

According to Advance Auto Parts:

KYB #344055 (rear) - $33.99 (ECE price $40.00)
KYB #344068 (front) - not listed (ECE price $40.00)

Re: kyb shocks/ part numbers
 

Thanks for bringing that to my attention Blckbuty. :dohh: Oh well I guess I'd rather give my money to ECE than Advance anyway. Although now they are going to be pissed at me for giving away the secret.

Re: kyb shocks/ part numbers
 

:lol: Hey in times like these every dollar counts. :D

Besides usually when you order parts by calling ECE they will usually beat the price you thought they were going to charge. Stan, Mark, and the rest of the guys are great!

Re: kyb shocks/ part numbers
 

EDIT: I have a different number for a 6" rear drop shock for a 67-72 truck. (KYB#344067).

I'm looking for the front shock number for a 4" drop. (67-87)

Anyone have this number?

Re: kyb shocks/ part numbers
 

Keith, depending on the drop will the shock be different? It seems like ECE only offers one set at least according to their site.

Re: kyb shocks/ part numbers
 

lolife, is your front drop all spring or a combo of springs and spindles? My point is that the spindle drop doesn't count when computing what shock you need.

Re: kyb shocks/ part numbers
 

I need a shock that will work with a 3" front spring. (I'm also running a 2.5" spindle for a total of 5.5" drop)

Re: kyb shocks/ part numbers
 

are those the 67-72 part numbers or 73-87. If they are 67-72 are they for coil or leaf rearend? I know that if they are leaf spring numbers they'll work for mine too.

Re: kyb shocks/ part numbers
 

jared78,... sorry your thread got hijacked.
The fronts will be the same 67-87.
The rear shock numbers I posted are for 67-72 coil spring truck. I will edit my post.
Maybe calling KYB would be the best bet.

Re: kyb shocks/ part numbers
 

Here's what I determined for 1973-1987 and 1967-1972 Chevrolet C/10 pickups:

1973-1987:

FRONT GR2 344068 Shock Absorber 2 RWD
REAR GR2 344072 Shock Absorber 2 RWD
FRONT GAS-A-JUST KG5409 Shock Absorber 2 RWD
REAR GAS-A-JUST KG5415 Shock Absorber 2 RWD
FRONT MONOMAX 565032 Shock Absorber 2 RWD
REAR MONOMAX 565036 Shock Absorber 2 RWD

1967-1972:

FRONT GR2 344068 Shock Absorber 2 w/ Coil Spring RWD
FRONT GAS-A-JUST KG5409 Shock Absorber 2 w/ Coil Spring RWD
REAR GAS-A-JUST KG5416 Shock Absorber 2 w/ Coil Spring RWD
FRONT MONOMAX 565032 Shock Absorber 2 w/ Coil Spring RWD
FRONT GR2 344068 Shock Absorber 2 w/ Leaf Spring RWD
REAR GR2 344085 Shock Absorber 2 w/ Leaf Spring RWD

FRONT MONOMAX 565032 Shock Absorber 2 w/ Leaf Spring RWD
REAR MONOMAX 565037 Shock Absorber 2 w/ Leaf Spring RWD

For the '73-'87 trucks it mainly depends on the type of KYB shock you want to purchase. As for the '67-'72 trucks it depends on the type of KYB shock, but also the type of rear suspension. It looks like there isn't a difference on the height, or lack there of, of your suspension travel. Low and slow... :D

KYB Shock Difference:

KYB GR-2® / Excel-G®
twin-tube shocks, struts, and cartridges
Purpose: Restores a vehicle’s originally designed handling and control

Calibrated to compensate for worn suspensions
Components and valving are designed specifically for each application
The best choice to restore OE performance and normal driving conditions
Built with quality that matches or exceeds OE
Coverage for domestic and import cars, trucks, vans, minivans, and SUVs

KYB Gas-a-Just®monotube shock absorbers
Purpose: Significantly increases vehicle stability, handling, and control over twin-tube designs.

Gas-a-Just is the replacement for an OE monotube shock
Ideal as an upgrade from an OE twin-tube
The more responsive monotube design automatically adjusts to driving conditions
Applications for cars, trucks, vans, and SUVs

KYB MonoMax®heavy duty monotube shock absorbers
Purpose: Maximum control for trucks and SUVs – stronger, more durable truck shock

The right choice for hauling, towing, or plowing
The best performer on harsh road conditions
Perfect for diesel trucks
Applications for light trucks, vans, and SUVs, including some lifted and lowered vehicles

I hope this helps guys...

Re: kyb shocks/ part numbers
 

Nice research guys...:metal:

Re: kyb shocks/ part numbers
 

I don't think the thread was hijacked, still some good info. I did call KYB to get some info on extended and collapsed lengths, but they said they wouldn't publish that info or give it out. So I got a lowered gr2 number that I can cross to a gas a just number. I just need a rear number for a 6" drop leaf spring truck. A 4" drop shock could work too, I'll just get lower mount relocators. Thanks again for the help guys.

Re: kyb shocks/ part numbers
 

i just bought the KYB #344068 for the front from summit for like $57 shipped for both of them... i called ECE and they wouldnt give any info at all, they said KYB builds some custom shocks for them? the guy really sounded like he was full of b.s.,

Re: kyb shocks/ part numbers
 

who did you get this number from? for teh 6" rear drop?

Re: kyb shocks/ part numbers
 

Holy crap this is awesome I just spent 15 mins doing a search for this post and nada nothing nope:uhmk:...all of the sudden poof there it is :metal:

Re: kyb shocks/ part numbers
 

I saved the cardboard ends off of the KYB shock boxes that I got from ECE. I some how lost the front box end,... and need that number.

The number I posted (344067) is for KYB 6" drop rear coil springs.

Re: kyb shocks/ part numbers
 

do you think the 344067 will work for the 5" rear drop?

Re: kyb shocks/ part numbers
 

For the most accurate information related to these drops I would contact ECE personally. However, I don't know why the 344067 shocks wouldn't work for a 5" drop.

Re: kyb shocks/ part numbers
 

this says that the 344067 is a shock for the front NOT the rear?

Re: kyb shocks/ part numbers
 

The front and rear shock absorbers on 67-72 coil spring trucks will interchange if you wanted to. I have done it before. Front to rear, etc..

Second, ECE simply has done the research and determined appropriate shocks for lowered applications which they buy from KYB. Then, they cover over the official KYB part number on the box with their part number to save their proprietary information.

There is no way in hell that KYB makes specific shocks just for Early Classic. No way, no how.

If you buy the KYB shocks from ECE (like I have done many times) when you look closely at them, the KYB part number is stamped into the shock body right near the bottom eyelet.

After buying a few sets from ECE, nowdays when I buy KYBs, I simply order the KYB part number from Summit to save a good bit of money. Sorry ECE, times are tight. A KYB is a KYB regardless of where they come from.

On lowered trucks, the KYB GR-2 is much more suitable than the Gas-A-Just units are. The GR-2 is softer and helps the ride considerably.

Re: kyb shocks/ part numbers
 

thanks alot "TX Firefighter" for the info....

Re: kyb shocks/ part numbers
 

I'm happy with my Gas adjusts on the front so I bought a set for the rear but have yet to install them. My dad went with the GR2 shocks for the softer ride and they are nice also. KYB's are nice shocks:metal:

Re: kyb shocks/ part numbers
 

If you are running the Gas-A-Just on the front, be sure and keep an eye on your upper shock studs. They have a problem with coming loose and wallowing the frame hole out anyway, and the stiffer shocks will agravate that even more.

Re: kyb shocks/ part numbers
 

just to give yall an update, i installed the KYB 344068 shocks on the front, and i am completely satisfied!!! the truck rides a whole lot better, alot let body roll for some reason? my only guess is that the old shocks were worn out but they seemed to be not too old?

Re: kyb shocks/ part numbers
 

On our trucks where we have flip kitted the rear, we have essentially moved the shock attach point up the same amount as the drop (usually 6 inches). I have researching shock data to try and find a suitable shock and many places list the extended and collapsed lengths. Would this theory apply in this example below?

Stock (rear):
Extended: 23.26" Collapsed: 14.23 Stroke: 9.03"

For a 6" lowered rear suspension and NO shock extenders, would you look for a shock with 6" removed from each of these numbers? That would be a very short shock in the collapsed position.

I need to get my notches done and do a full extension/full retraction test and see where the numbers lie and shoot for a shock that has the range I'm looking for. I have found that when you start looking at shorter length shocks, the shaft sizes and body diameters shrink also, and that's not good on a truck.

Re: kyb shocks/ part numbers
 

Here is what I know.

If you buy a front shock from ECE, it comes with their sticker on the box making the KYB number unreadable. The number on the shock is 344068. I ran these shocks for 100k miles on my 72 with drop spindles and 3 inch drop springs. Never bottomed out the shock. They are plenty good for 3 inch drop coil application.

In the rear, again ECE sourced shock, true pn 244055 works well with a 6 inch drop and aftermarket shock extenders like ECE, etc. This shock will allow the axle to bottom completely to the frame and still not fully collapse the shock. With 6 inch coils and any lowering block combo it will serve you well. Keeping in mind that only the coil affects shock travel. A lowering block does not affect the shock length.

Re: kyb shocks/ part numbers
 

All of this shock information is splendid!

Re: kyb shocks/ part numbers
 

Any suggestions for a KYB part # on a 5" axle flip it leaf spring drop in the rear.
