A 96 hub is .093 shorter than the 94-95 to allow for the reluctor.
If you cant find a 96, you could machine a 94-95.
Orrrrrr, in a pinch shim the accessory bracket ahead.

Goes without saying the B body hubs for a given year are longer than F or Y

Hey thanks for the reply 95wagon, but im really wanting something i can order or pickup somewhere, i dont have time to get one machined , i might just slap the old hub in and hope it stays in place if its going to be a hassle looking for one ,was really wanting a pioneer one but seems like they don't carry it anymore. 😤

I ended up having to buy a 95 and got my local machinist to cut it down to 96 specs for me. I want to say it only added about $50 to the cost and was at his shop for a week.

You can lead a horse,,,,,,,,,,

The seller I linked is none other than TorqueHead.
Think they would have their #%^$ together.
The 94-95 hub is the longest there is, the 96 is only .010 shorter ( .093 but not nitpicking)
Damper sellers like ATI , Fluidampr, and the hubs TorqueHead sells, are 96 dimension and include a shim washer to use if you are putting on a 94-95.

Contact TorqueHead directly if you have concerns.
Yes , the keyway is correct.

Your car stock will have no key in the front position, and the special " clipped" LT1 and year specific rear key.

The correct set up when using a keyed hub is 2 full length keys .
Lots of people, if the engine is together, skip the change of the rear.
Maybe OK if NA and you just want the added insurance.
If there is a blower involved, you MUST have both full length keys.

Ok just contacted him waiting on response, so will this hub also be tight to replace like orginal thats pressed or will it slide on easier? Thanks

It better be tight fit. The fit is critical to both the operation and retention.
Look at other engine types that have slip fit dampers, they will typically have giant damper bolts torqued to big numbers.
SB chev, is only 7/16-20

As per ATI
" Press fit of the hub to the crankshaft is vital to transfer harmonics to the damper assembly.Recommended press is as follows:Crankshaft ODInterference Crankshaft ODInterference1.0000" - 1.2500"-------------.0009" to .0012" 1.6010" - 2.0000"-------------.0006" to .0008"1.2510" - 1.3750"-------------.0008" to .0011" 2.0010" - 2.5000"-------------.0005" to .0007"1.3750" - 1.6000"-------------.0007" to .0009"

Ok kool he just replied back this is what he said



Hello,

Yes this is direct replacement on any B-Body application for 1994 to 1996. 1996 Impala SS with stock crank pulley....this is spot on compatible. Its just better design as its billet, keyed, and all that good stuff. We install hundreds and hundreds of these on many many LT1 platforms as we carry all hubs for all platforms.

Regards, TH



So with that being said i pulled the trigger,if anyone is looking for one this is compatible with 94-96,thanks everyone for there help.

Gerry is correct. It comes apart.
You get the hub and balancer together for one low price. ( And spacer for Bbody)
