Hey guys I gots a ? I recently bought a 90 yj. It has 35 inch tires. Stock axels motor and tranny. I took it to the mud drags thinking it was badass and got my ass spanked all night. I mean bad. So my ? Is what can I do to make this thing scream down the track without emptying my wallet???
Yeah ugghhh stock axles and u want to hammer down on the skinny pedal? find a used cheap axle for the rear (upgrade) like d44 or ford 8.8 regear it to 4.88 or lower (lower gear wise not numerically) or go maybe 5.13 and do the same to your front axle same gearing. Shops charge big money for regearing so if u can or someone u know can gear it low and upgrade that axle is a start!
Stock 4.2carberated three speed and I believe a 231 tc I was told that downsizing the tires a bit would. I'm currently running a 35 14.50 15. The truck looks great just doesn't perform like I would like it to
U wana scream down the track.... gear it to 5.13 or lower. Which will destroy you highway speeds but you need a different rear axle and if your scurred of breaking the front one get some chromoly axle shafts for the front.
No tcase was in high and the track wasn't all that muddy. So u think a different trans would help. I have a 700r4 with a np231 tcase in the shop but the out put is on the wrong side. Is there any way that trans would work with out swapping engines
