13/14 LCA's upgrade for 08?

[mike97gt]

Hi Guys,
I recently purchased a 2008 GT500. Performance White with Vista Blue stripes. 30,000 miles and completely stock. Currently parked for winter
I have a friend who has a 13 GT500 who has upgraded quite a few parts and I was wondering what stock pieces on the 13 would be an upgrade for mine.
He has factory LCA's, driveshaft, supercharger pulley, balancer, and a few other parts laying around that he would give me for free or at least for dirt cheap.
Are any of the listed parts an upgrade for the 08? And does anyone know if the stock 2.6" trinity pulley will fit on my factory eaton?
Thanks a lot. I'm looking forward to start upgrading this thing. I can't keep anything stock for long

The rear LCA's are the same as far as I know, 2007-2014. The oem 2013 CF driveshaft would be an upgrade if you can find the adaptor needed for the install in a 2007-2012. I don't think the 2013 balancer would be an upgrade for a 2008. The pulley? IDK.

I think the LCAs had higher durometer rubber bushings. Later cars are not as prone to wheel hop as the earlier cars. In any event, the rubber in that 2008 arm is now over 10 years old anyway. Pulley's aren't that expensive. I'd buy a new 2.5".

They may be a higher durometer rubber in the newer LCA's, but I believe the 2011-up UCA and it's more robust UCM may have also been a big reason for the lessening of wheel hop on the newer cars.

Thanks guys. I probably won't bother with the parts then. Unless I can find adapters for the driveshaft.
But in desperate need of some LCA's. Wheel hop is nasty in this car. Are relocation brackets a necessity wit the BMR LCA's? Might pick some up tomorrow with black Friday sales.

Relos not necessary but come in handy. I am not lowered and have relo set in the middle. If you are going to lower then you should have them,.

The Roush UCA stopped the hop in my car.

The Roush UCA stopped the hop in my car.

I have read other posts where owners were satisfied with the Roush Anti-Hop UCA.

Below is a side-by-side of the oem 2007-2010 (left), the 2011-up Roush (center) and the oem 2011-up (right)............

Below is the Roush 2011-up (left) and the oem 2011-up (right)............

For 2011-up, all Roush did was upsize the bolt under the rear seat, but they did not increase the length, as Ford did for 2011 and they did not design a more robust UCM, as Ford did, and the through bolt on the Roush retained the smaller diameter as the 2007-2010 oem UCA/UCM bolt.

The through bolt size differences, oem 2011-2014 (left) and oem 2007-2010 and 2007-2014 Roush (right)

I might as well add the close up of the oem 2007-2010 and the 2011- up Roush also while I have the pictures pulled up..........

Thanks for the info Robert. Looks like a better mount with the 2011+ OEM other than the big rubber bushing on it. Roush may be the better option as the bushing looks small and less prone to flex from the pics you showed.
I plan to get the BMR LCA's to try first. I think I can get the factory UCA from my buddy with the 13 so I can try that setup and see how it works. Still another 5 months until it's back on the road anyways so I have some time to decide what I want.

I test fitted the longer oem 2011-up UCA/UCM on my 2008, to make sure it would fit and not contact the fuel tank (there was a fuel tank lip change with the longer arm in 2011), and all fit nicely in place on my earlier car. The oem 2011-up UCA worked fine on my 2008, but I ended up buying a 2011-up BMR, just to get rid of the rubber in this area. As I had mentioned previously, there are many owners who like the Roush, the tighter bushing really helps minimize bouncing of the UCA. Supposedly the Roush mount is made of a thicker gauge metal so it does not flex like the oem 2007-2010 mount, but I have not placed a dial caliper on the two mounts for a thickness comparison.
