Rear Diff and drive Shafts

[S800VXR]

This is aimed at Gareth but if anyone else knows...

Whats a good replacement for the stock LSD setup and half shafts.... I want something that will stand up to a hard launch with drag radials with about 600rwhp going into it!

Gforce1320 anti wheel hop shafts, kaaz or eaton diff or harrop 12 bolt if you have the cash. I think the 12 bolts are what harry and jez use.

The fish are now gforce1320 dealers, looks like i was wrong about the 12 bolt i dont think you get the prop and shafts with it but have to, to get it to fit.

I fitted a Detroit tru trac (gear) diff, which has since worked very well and has not grumbled at the abuse given. The only concern originally was that the stub axles seemed a bit of a sloppy fit in the splines, but I have not had an issue. Some of the US shops are offereing the harrop version for a bit more

I brought back a BMR 300M HD shaft from the states for the drivers side. $499US. This should do the trick. After speaking with Roger the Fish, I'm not too concerned about the prop shaft as he says the 6.0 litre cars had an uprated item from the earlier 5.7 motors. Having said that I will be fitting a Normal UJ to replace the doughnuts.

If anyone is interested in a group buy of diffs I will be wanting another for the GTS.

Gareth - PM me if your getting something for your 4 door family wagon as Im thinking I may as well fit something now to save the stock setup braking when I have to nail it off the line this year to stay with you!

This is a good article: www.highperformancepontiac.com/tech/hppp_0609_2004_pontiac_GTO_halfshaft_upgrade/index.html

I'd also look at these:

I have heard the after market drive shafts bust just as regularly as the stock ones and should be considered consumables if you lack mechanical sympathy. My standard diff has been rebuilt once but apart from a Harrop diff cover, torque damper and poly bushes, mine's standard. I have too much mechanical sympathy to drop the clutch off the line and I predict if I did something more expensive than a drive shaft would break. IMHO, you strengthen the back end, the front end will break instead.

Heavy car+sticky tyres+high torque engine+hard launch=something broken.

this is what i was talking about

I know the shaft Gareth has looks very good and should do the same job as this anti wheel hop kit.

Hmm, may have to talk to Roger about the passenger (driver) upgrade for the G8(vxr8) as mine hops like hell unless I have lent on the brakes for the burn out. Its bad on the road.
