Could the shock mounts on the a arms be relocated to achieve the same result? Then the frame wouldn't have to be modified.
Nope that is as far as they could go before they hit the upper arms with the stock A-Arms. Right now there is under .25" clearance on the upper arms through the cycle.
I'm working on putting LTR-450 shocks on the front of mine. I have to re-do both the frame mounts & the A-arm mounts.
Brian you do not have to redo them but if you want the ball joints to be correct with these shocks on the OEM a-arms you will need to move the upper mounts like I did. I know you have some special Baja arms and the YFZ 450 shocks might work good with your set up if done right.
In fact I might know someone what a set for sale if interested get in touch.
