Thread: Prothane Bushings

I was doing some random googling online and came across this

Prothane Suspension Parts: Chevrolet 2WD Trailblazer 2003

02-03 Front Sway Bar Bushing Kit, 44mm bar 7-1186
02-03 Front Sway Bar Bushing Kit, 46mm bar 7-1184
04-05 Front Sway Bar Bushing Kit, 34mm bar 7-1187
02-05 Rear Sway Bar Bushing Kit, 24mm bar 7-1185

IIRC, the EXT has a different rear sway bar than the SWB, and there was also a difference in front sway bar size. That link has two different size front sway bar bushings and rear sway bar bushings. I can't afford the stiffer sway bar, but want to reduce the EXT body roll. I've already replaced the OEM shocks with Bilstein HD's all around. I think this would be the next best thing

Every little bit helps. The poly bushings will cut the slop/play in the sway bar caused by the soft rubber oem ones. They are a good supporting mod to other suspension work.

Thanks for the part numbers. Added to my "to get" list.

As a side note: these are ONLY for 2WD vehicles. They told me don't offer sway bar bushings for 4WD TrailBlazers.
I went with the ACDelco poly bushings from RockAuto.

BS, they all run the same dang bushings, 2WD/4WD/AWD. Identical.

The years make a difference for the fronts, 02-03, 04-07, and 08-09 are all different. Rears are the same regardless of year and, I believe, wheelbase. I.E. SWB and LWB trucks are the same, but dont quote me on that. I also thought the rears were 26mm too, hmmm.

I dont think AC Delco makes poly bushings...pretty sure they'll be stock rubber replacements.

My original bushing were worn to the point where I could jiggle the sway bar with my hand. Did some digging and Napa had the polyurethane as recommended from other members at the OS. I know for sure that the 2002s use the biggest size possible. It does make a difference in handling. I haven't done the rears as yet.
