spools Yep aftermarket axles should be a must and full spool obviously requires c-clkip emil kit to retain the axles in the housing. Jim

performance posi or truck loacker? I think the real question here is do you want a Performance limited slip or a truck locker? The posi /limited slip /locker found in the s-10 and most all trucks are Gov lock limited slip units...THEY ARE NOT MADE for performance type driving...

motor info If it is just street why would you want all that stall??? Horsepower and torque numbers do not make any difference on the pick of the stall till you can tell us WHEN the torque hits RPM the power band of the cam what motor, cubic inch, cam selection, carb size, intake manifold...

slicks Well slicks play by different rules than any other tires... You do not need a large slick in width or diameter to get the power to the ground. Unless you have a low 10 sec car SLICK tire size should NOT be an issue. Pick one that fits and runs the correct RPM through the traps...

rear end Ok - Not trying to cut anything down...BUT you paid 800.00 for the housing and only 240.00 for the essential parts that will take all the power only 240.00??? Something sure seems a little uneven...lol. I wish you well with that... BE CAREFUL. To the question. rears- You...

G80 code limited slip All GM vehicles car or truck that have limited slip (posi) are G80 code. G80 does not determine the actual type of unit that goes into the vehicle. Trucks will generally get the eaton gov lock and the car will recieve the perfromace posi (auburn eaton or torsen)...
