has anyone used the speedometer recalibraters that summit sells made by Jet performance or superlift suspension? i just changed out the 3rd member in my truck and the speedo is way off now (reading too fast). and im not going to fork out the cash for a set of new 32's. im hoping these are worth the money.

 

their kit is for the electrical speedo, not the cable driven, correct? if you have a cable, then i dont THINK its going to work, cuz to change the reading with a cable speedo, there are gears in the tranny/xfer case, whereever you hook up that end of the cable, real tiny, very precise gears. if i remember correctly, larger gears show a slower reading, smaller gears show a faster reading.

 

Yeah, OP, You need speedo gears to "recalibrate" yours..

 

i just bought the correct size tires for my 5.29s

 

i have a '94 with a electric speedometer. so the cable gears wont help me. i just want to know if anyone has used either of these before.

 

bump, anyone?

 

call em up, dawg

 

call who, summit? what good would that do? i was hoping someone on here had used ones of these so i could find out how to wire it up and how good it worked but, i guess i will have to be the guinea pig.
