Im about to get my 35 mud grapplers for my truck, I was wondering if this has any negative effect on the engine (4.6) 2007 screw 4x4. I already ordered the AS 2.5 for the front and the 3" block for the back. Thanks in advance.

 

ya. unless you have a chip, exhaust, and an intake its probably gonna cost you some power. you should get new gears if you plan on running 35"s. btw, mug grapplers are not good tires. they wear horrible and are really loud. they are much better mud tires out there. the KM2 is probably one of the best

 

x2 the mud graps look cool but like buckles said theres mud tires out there that will last longer and still out perform the mud graps

 

x3 with them and x2 on the bfg km2's awesome tire several guys on here with them and love them.
