ex400

I did not have to shave the 450 shocks when I mounted them,I just took a screw driver and hammer and knocked off the nut welded to the frame that holds the front plastics above the shock.Then used a smaller carriage bolt upside down and bolted everything right up. The shocks made a big difference.

None of the oil filters I have changed on my 2001 and 1999 trx 400s have anything written on them.
