I've bought all the stuff for my 4.10s, now im just waiting for them to get here...just making sure, is there anything else i should know about drivign with them before i get them installed?
I can't wait to tear up 2nd gear on the road

Yes... you will need the speedo recalibrated unless you already have something that will do that for you.

 

I was just gonna cruz around with my speedo at 100 until i got pulled and see what they say i was going

 

That'll work, but your odometer will pile up miles quicker too.

 

Be prepared to have a lot of fun!!! And of course save some $$ on new tires that you will have to buy next month
M6+4.10=No traction=fun!!!!

i LOVE my 4.10s

hell i've been thru it all .. 3.42 .. 3.73 .. 4.10 .. and everytime i get a new gear i want more !! 4.56s are next probably

 

What brand did you go with? Are you going to put in solid shims in lieu of crush sleeve?

 

I got some motive gears on ebay for around $140 new, and the installation kit from thunder racing which says:
Deluxe Kit: Includes pinion shims, carrier shims, crush sleeve, pinion seal, pinion nut, ring gear bolts, cover gasket, pinion & carrier bearings, PLUS wheel bearings and seals. (All of the small parts and pieces necessary to RESTORE an axle to like new condition!)
so there are your crush sleeves
I hope it picks up speed...my friend has a 2001 formula and nobody around here can beat him...hes running 13.0's on street tires and just got some ET streets that will probably let him hit 12.8 or so.....needless to say I have the car that needs to beat him

 

it would be a close race but I think the ls1 will have the upper hand... spray him

I'm still driving around on the stock 3.42's maybe i should upgrade to some 4.10's also

 

I only ran a 14.1 with intake and exhaust....any idea how much i could shave with the 4.10s? I just got home from riding around in his formula, damn its so fast compared to mine....one day, one day...

 

Im with sideways i love my 4.56's, dont get me wrong i liked the 4.10's but the 4.56's are great. ahh who needs to recalibrate? 2000 rpms =70 (in 6th of course)

 

Do you need a tune after you put in 4.10's? Is it just for a speedo recalibration or is it more? We will be putting 4.10's in my friends 95Z 6speed soon. The car has the usual bolt on's so far, headers, I pipe, muffler, LT4 springs, 1.6 RR's, underdrive puller, MSD, air foil, CAI. TB bypass

 

how can you tell what gears you have already?

 

All you need is speedo recalibration.

 

Get a Solid Pinion Spacer instead of using that crush collar.
Also, a new rear cover with bolts that press onto the carrier bearing caps. I am having a brain fart and can't remember what they're called.
