This is a replacement GY6 150cc engine for your Tomberlin Crossfire 150R buggy as well as some models of the Baja Reaction.  The exact Crossfire engine is no longer manufactured or available ANYWHERE.  With this replacement engine you'll need to space over your axle sprocket using some washers and grade 8 bolts and you'll need our Crossfire 150R engine replacement kit.  The internal reverse, on the replacement engine, operates a little differently that the reverse on your original engine and this is why you need a different shifting system.

If you have any questions call our technicians at 474-447-4870 and they will be able to 100% guaranteed the fit for your vehicle.
