Re: EF/L XR6/8 Diff into EA

you will need the tailshaft from the car as well. You will also need o get new bushes installed in your lower control arm bushes.

Re: EF/L XR6/8 Diff into EA

i didn't use the EF/EL tailshaft - i just swapped the yokes over on the diffs, they are both BW. i did however have to swap the lower trailing arm bushes to EL XR ones, and i had to get 2 new flexible brake lines to suit the EL calipers and i am yet to sort out the handbrake cable issue.

Re: EF/L XR6/8 Diff into EA

To put the diff from an EF or later into an EA- ED theres a few things to consider.

Brakes: Run the original brakes and discs that were on the old diff. The EF/L has a very different brake system. The original discs/ caliper plates will need to be swapped over which is easy. The brake line junction point (breather hose) is also mounted further out than EA/D diffs. You need to be cretive and bend the lines a little.
Axles: If you have a 28 spline diff its best to use the axles from your diff as the EF/L studs are longer and some of the earlier wheel nuts have closed ends and bottom out before the wheel is tight. If you have 25 spline axles you will most likely need to get open end nuts.
Tailshaft: An EA will need the later model (EB onward) tailshaft. You can change the yokes over as someone mentioned above.
Trailing arms: If possible use the EF/L upper trailing arms. They will clear the diff housing when diff is at its full travel. Some diff's (xr diffs do) use different upper trailing arm bolt hole positions to apparently increase handling. If it is going into an EA you will need to either get EB style bushes pressed into the diff side of the lower trailing arm. OR get EA bushes pressed into the body side of the EF lower trailing arms. This doesnt apply to EB onward as they use the wide style bushes from then on.

I did this to my Eb2 Ghia with an EF XR6 diff.

Re: EF/L XR6/8 Diff into EA

do you think 3.45 Ratio with 15" snowflakes will be too much for a t5 everyday ?

my brother has a 3.5 9" in his xy and it tops out at 140km-150km (3sp fmx box)

Re: EF/L XR6/8 Diff into EA

3.45 + t5 + snowflakes = 230kmh+ top speed no worries (if you have the power to get there
