Ground clearance on the frame crossmember limits up travel and then the axle limits droop. If you look In my 4runner thread I have a picture of the c.v. I clearanced. I got 13 before adding straps and bumps and all that. At about 12.5 also on mine now. You could probably get more if you built custom arms and custom axles but with T100 axles 12.5-13 is the limit.What's limiting?
Frame/earth. Didn’t wanna cut any more frame out for bump travel. As is at full bump with 33s i got about 5 inches or less between the ground and the cross member. As far as droop the shocks are the limiting factor since I only have so much room to angle them around with the axels and the boxed upper arms.What's limiting?
