are 30" long and available in a variety of rates.

port ribs for housing reinforcement, 
a thick, durable snout, and “bat wing” 
pinion bearing support for increased strength and housing 
rigidity. Housings are complete assemblies, fi tted with the 
highest quality ring and pinion sets, 4.12 ring and pinion,

same dependable ring and pinion as 
the XR-1. A mix of space age design and 
old fashioned common sense make Bulldog XR-2 the premier 
rear for sprint car racing. Natural magnesium fi nish.
