CJ FULL WIDTH CONVERSION KIT

The Poison Spyder Customs Full Width Axle

Conversion Kit is designed to mount full width

axle assemblies underneath ‘76 to ‘86 Jeep CJ’s

(CJ-5, CJ-7 & CJ-8). The kit is designed to fit

axles with leaf spring perches that measure 31-

1/4” center-to-center. This includes most Chevy,

Ford, full-size Jeep and Scout front axles.
The bolt-on front outboard bracket locates the

front spring perches outboard by the correct

amount, while also providing for the shackle

reversal. The kit is designed to be used with

2-1/2” wide leaf springs, but narrower springs

can be used with spacers (not provided). The

front bracket also moves the front axle 1” forward

of the stock position to assist in tire clearance as

the axle rotates rearward under compression.
The rear weld-on bracket locates the rear shackle

hangers outboard and allows for 10 different

shackle hanger mounting positions.
