Rear arb bush size ....

Can anyone tell me the correct size in mm for the rear anti roll bar bushes poly pro suggest 12mm 13mm 14mm and 16mm so does anyone know the standard size arb ?

i thought standard was 15mm

Close Mr B, just micro'd my old one, 16mm

Pretty sure bushes for oem bar are 15mm and bar around 15 or 15.25 .
I'll measure one later see what I got as if poly-pro not listing 15 and you 16 on standard then I likely wrong .probably worth nomad checking his as may not be standard .

I cant find my digital calipers to measure it .... any joy on your one mr b .... i know the whiteline one is 20mm .... the front whiteline is 27mm ... not that helps me out lol ...

try use a 15mm and 16mm open end spanner, I not done it tonight but will tomorrow .

Yeah i painted it so probably a mm thicker .... im just intrested now why so many different sizes ... the 200sx ones are 15mm

Even powerflex list variations on rear arb sizes although it doesnt state what sizes ..... so would you say if the arb is say 14mm would you drop the bush down 1 mm so its a tight fit ???

Well measured one and it 15.18mm so 15mm . Powerflex use to list bush as 15mm for rear arb as far as I remember so that could be where 15mm came from .
You would choose bush size same as rollbar really, manufacturer would control exact bore size pending on material of bush etc((rubber likely want be tighter final fit than harder poly).
could be worth contacting you bush manufacturer for their input.

Just measured mine again in daylight and on 4 points got an average less than 15.2mm so Mr B at 15.18mm good measurement.

Il contact powerflex and find out what sizes they offer as poly pro dont do a 15mm .... still yet to measure mine .....

I would contact polypro as pretty sure I seen a 15 in some of there listings.

Below powerflex and the bible S.D.S data 'chapter RA39 . Vol2' .
