08 nytro with 2010 subframe ?

The 2010 spindles and a arms are different. You should still be able to use your 2008 if you want, the spindle angle etc is different so you can't mix and match. On the CR front end just ask Chad if the a arms and spindles will mix. Most aftermarket a arms are designed to use stock spindles, but some are designed with their spindle only.

the spindles are the same and the lower control arms are the same its just the uppers that are different you need to change the pins and bushings and order the 2010 arms from chad, to work with the 2010 sub frame.

Are you sure about the spindles being the same? Pretty sure they are different from the 2008 to the 2010 mtx or any of the versions with the new geometry front end.

I installed a 2010 frame in my 08 FX Nytro RTX. The updated frame fits all 08-10 Nytros. If you want to update the front end geometry like the 09's you'll need to change spindles and A-arms. The 2010 frame is suppose to have stronger gussets but I've heard reports that it's no better than the previous version so I welded gussets in. http://s589.photobucket.com/albums/ss337/grizztracks/Nytro subframe gusset/

The 2010 frame is completely compatible with a 2008 Nytro. The 08 a-arms, sway bar, plastic..... all fit. I also installed the Ulmer bushings in my 2008 Nytro. Because there was a change to the a-arms in 09, the 08 and 09 bushing kits are different (order the 08 kit for 08 a-arms). When installing the bushings be careful not to brake the flange on the upper bushings. Ther're thin and brittle. A bushing driver is recommended for installation but if you don't have a set a socket can be used to drive them in. Putting the bushings in a freezer to shrink them also helps.

The biggest improvement in the frame since 2008 is the addition of the large rear gusset plate. The smaller plate added between the a-arm mounts does very little in reducing bending caused by low impact. Even with the 2010 materials update to the gusset it's not strong enough and more importantly it's not located properly in the frame. The lower a-arm mounts are weak and also need addition support. The gusset that I added strengthens the mounts and lower subframe by tying them together. If you're installing a new frame I'd add similar gussets.

This is what I believe happens when the Nytro experiences a one sided low impact hit.
