    Roll Design A-Arm Question

    So I have a quick question, that is hopefully easy to answer.

    Are the Roll Design A-Arms for the 400ex and 250R the same? I was just looking at the website and saw that under the 400ex they list the A-Arms as for a 250R and are the same part numbers.

    Now I know that 400ex arms will work on the R chassis with spacers. Now my question is, are the arms offered by Roll for both the 400ex and 250R the same, with the only difference being the spacers or bushings for where they bolt to the frame?

    Thanks

ID:	6406checkout pic. not sure on that but i bought a 86 trx250r and it was completely rebuilt with roll design a-arms on it with 1,000 work shocks on front. i new nothing about those a-arms except visually they were long travel cause of the long shocks. i looked them up and almost fell over. 1400 bucks? i kid u not the bike is brand new powder coated frame+swingarm, 750 buck rear work shock, roll a-arms, alum air box/38mm/k+n, all new plastic with carbon fiber hood, 4 new rims/holeshots, 1,000 plus 2 rear axle with new hubs/disc. its a stock topend, maybe bored 20 over. fmf fatty and silencer, 165 main jet, asv levers, bike absolutely hauls ass. must have a stroker crank in it or something. it looks completely stock to the eye. unreal fast. when i race it against my stock 250r its useless. so bad that if i raced a stock 250r against a 250ex....the 250ex would look like its doing a good job. hope ur sitting down...he wanted 3,500. 3 mths later he came down to 2800. then 2600. and i stole it for 2,550. 3rd owner. the guy before him had to of had 5,500 plus into it. easy. 1986 that is now a 2012 model. brand new everything.

    the difference between 400ex and 250r shocks are a small spacer you have to add at the mounting points, 400ex is narrower.

    if your buying used be aware that the rebuild for roll arms bushings and such is expensive

    That right there answers your question, same part number, same arm, unless there is a typo on the website. I am sure when you order, Roll just includes the correct spacers. Teixeira Tech does the same thing. They make 250R arms, but they also fit 400EX's, and even Cannondale's, just different sleeves and spacers are included depending on what quad they are going on.

    Most Roll's use 18.75". But you shoudl really measure out the arms once on the bike to get the optimal performance with tire combination. Doesnt make sense spending all that money on shocks and not get them setup properly IMHO.

    Not totally sure exactly but when you have your front completely bolted on let your arms drop all the way and see what distance is between shock bolt holes

    That is not how you measure shocks.

    Maybe not exact but if u measure 17” hole to hole pretty sure not gonna be running a 18”+
    usually see about 1/2” shorter difference from total length
    for rough estimate...
