drill spring perch?

[bad_religion_au]

ok, mind is racing now.

i have read drilling chassis= weaker

drilling spring = weaker

how about drilling spring perch to move the rear axle on my 40 forwards (longer than stock springs, trying to get it to fit with the "propane" tank under the back)

strength issues???

do you think i could get 1.5 inches out of it.

how about more than 1.5 inches?

No problem. People do this all the time. No strenght issues if you don't drill too close to the end.

Did my rear axle that way. I extended my wheelbase by redrilling the perch 1.25" forward. That moved the axle back 1.25". Did the opposite in front, only by 1". Simple way to gain some wheelbase.....YMMV.

so how close is too close to the end of the spring perch? would 1/2 to 3/4 an inch be enough meat to leave in the perch (i'm trying to get as muc as i can.

does this affect U bolts or mounting much?

you will have to drill out the plates that clamp the spring pack on the axle to match the offset of the center hole on the spring perch

u bolts will be fine but i recomend using new ones

so how much space should i leave before the edge
