If you are fitting the subframe to a standard Cub, you will need spacers and a slightly different fitting kit. Please tell us when ordering so we can supply the right package for your machine (fitting kit £10)


The Armac front frame is narrower than standard, so to fit the Armac subframe to a standard frame you must reduce the width of the upper subframe mount by 5mm each side, to an overall dimension of 40mm. Drill through the same mounting with a 10.5 dia. drill. Drill out the lower subframe mounting holes to 9 dia. A fitting instruction sheet will be supplied with the subframe.

PRICE: £495

Std Cub fitting kit: £10
