I have them on my little kids 80cc but i WOULDNT put them on a raptor 660, They just dont look strong enough for jumping, for a kids quad yhea but I wouldnt trust them on a big quad with a big person on it.

 

We have them on the 300ex and the Blaster. (1 1/2" size, back only) We ride alot of woods and some pretting good mx tracks and have not had any problems so far. Ours have took some really hard hits with no problems. For example, my youngest son on the Blaster, has tore the top ball joints out of both the stock upper a-arms jumping our table top. Not to say its the best way, but its better than some.

 

So would you say to go ahead and get them? The Spacers for the 300ex would be the same as for the raptor? How thick are the bolts?
