im looking at aftermarket poly sway bar bushings and end links, can anyone tell me the exact size of the front and rear sways on a 98 park ave ultra with the F41 suspension so i know what to order from energy susp.
thanks

and also the length of the links...
thanks again

Part number 9.8149R through energy for red and 9.8149G for black...Those are 4 and 1/4 inch otherwise it could be 2 and 3/8 inch youll have to look

f41 should be 22mm sway bar

for the front? 22mm sounds small.. thats 7\8. isnt that what the fe1 had? just wondering. your probly right tho. thanks

Far as i know FE1 was 18mm and FE2/FE3/F41 are 22mm

theres a 28mm from a riviera for $20 near me for sale.. would i feel a big diff from 22mm to 28mm?

Yes. I believe you would, especially with poly bushings.

Bigest rear is 22mm bigest front is 34mm which came on the Deville . The same one we get the radiators support bars from. The 32mm and 34mm are very heavy. Especially if your carring them through the u-pull with your tools. Normally i take a hand truck but was only looking for small parts.

By the way i have checked many sway bars in JY'* and they are not always the same in each make/model. I've seen low opt cars with bigger sways than models such as Park Ultra. So you need to check. An FE3 Bonne SSEI had a 30mm front. An 89 Bonne LE had a 22mm rear. Well you get the picture. But the caddy'* all had the bigger sways on them.
