2" shorty
 

Has any buddy put on 2 " shorty and gained speed.And stand off boxes.Or tried sportmaster lowers.On a 37' What speed did you see.

AT does not use a conservative X dim at all. I would think a 2" raise would be too much.

Clark has a buddy that spent a lot of time dialing in a 37 in TX with 12" Stelling boxes. It worked well, but it was not a turnkey setup right out of the box.

Rich tried just about every single B1 combination/derivative drive on his 37 with Whippled 525s. The best performance was right back with standard XRs.

Thanks , Sounds like i better not touch anything on the outdrives.

Hey guys do you think stanard xr sport master lower will work ok.I need to replace to lower cases.

If it isn't running triple digits you will be disappointed. What power?

stock 525s for know.
