FAT 5 ™ OVERDRIVE

FAT 5-SPEED OVERDRIVE COMPLETE TRANSMISSIONS & OVERDRIVE SUPERKITS

Got strong? We have strong! JIMS ® “Fat 5 Overdrive” is simply the strongest, toughest gearbox made. Period. JIMS ® took advantage of its new, more compact shifter technology to increase the width and strength of every gear. The width increase varies from 18% to 53%, depending upon the loads each gear set must carry.

Big power is more popular than ever. Large engines like the JIMS ® 135” deliver double the stock power and torque. When such power is linked to the ground through high torque clutches and big sticky tires, the peak loads on transmission gears rise far above what anyone but JIMS ® ever expected their trannies would need to endure. All are available with a mechanical clutch activated system only. The Fat 5 Overdrive fits both Evo and Twin Cam ® chassis. However, it is wider on the right side which may interfere with other components. For this reason, we consider our Fat 5 Overdrive to be part of a custom build and not a drop-in product. It is available as a JIMS ® Super Kit or complete transmission. As you’d expect, all Fat 5 gears are manufactured to JIMS ® renowned standards of strength and quality. For more details see No. 8273-IS instructions. Fat Gear™ complete transmissions are shipped as a complete assembly installed in a case. Transmissions DO NOT include pulley. Fat Gear™ Transmissions are a CUSTOM application. Modifications to the exhaust bracket and oil filler spout may be necessary. PART NO.
