I have 1994 Chim. I have been offered a free set of callipers and uprights from a 89/90 Sierra XR4x4. Are these a wothwhile upgrade? Is it a straight forward swap?

Thanks

They are for 260mm discs.

You can use the calipers & carrier brackets but will need 2wd discs (look up XR4i or later ABS model sierras) & new pads.

Make sure you haven't got 260mm discs already first!

I have the smaller discs. For the cost it seems a worthwhile improvement in braking?

Do you think the cosy setup would be over kill on a 4.0ltr?

I will get them reconditioned first.

Dont hold me to this but you may not need the uprights,i had the puny 240mm set/up (1995 car) and upgraded to Granny Cosworth calipers and discs and did not need to change the uprights just a small mod on the hub caliper lugs(which you may not need)i would see if the calipers with the carriers bolt straight up with the matching 260mm discs 1st,hopefully you may not need the hub swap,remember all IMHO of course smile oh,just one more thing dont worry about the fronts being to powerful that wont happen,it will be all good.
