The BullDog SS-1 is the newest rear in the BullDog Quick Change Rear family. Designed for crate –powered Modifieds and Late Models. You asked for it and BullDog delivered. We started with a blank screen and put over two years of design and development into producing the shortest, quickest and strongest full size appearing rear. The rear features reduced rotating and unsprung weight and additional fuel cell clearance. Ultralight 8" ring gear and mini pinion assembly is over 2 ½ lbs. lighter straight out of the box than a standard 10" gear set. The BullDog Super Short -1 is the shortest rear available from any manufacturer. The rear is more than 1.5" shorter than our already industry leading CT-1 rear. The rear utilizes our standard side bells and tubes as well as standard 10 spline quick change gears. The pinion is supported by one piece pinion bearing cup and revolutionary pinion nose support. Crate cars and lower horsepower applications will see the largest difference in acceleration and deceleration. There are short rears and then there is BullDog Super Short!

Also call us if you are ordering large items like race car bodies as those are hard for the freight system to calculate sometimes and it will overestimate. Thank you.
