Hi All,

Can a 1lt T'fer case be used in a 98 sierra??? Wanting some better low range gearing. Any ideas?

Thanks

Adrian

i think they fit but you need a leafie jack shaft, i could be wrong but.

Thanks Shep

pritty sure they fit,but you have to get one with a 4wd switch,and you have to change the flanges,as the 1l ones dontmatch up to the coily ones...also you may have to change the handbrake setup(1l have drum brake on the t/case for handbrake.)

Anyone feel free to correct me if im wrong?

Mr unique_seek is on the money.

Also, the front driveshaft ends up a bit too long (the coil case is shorter front to back than a gear drive sierra case)

Might be OK, but on the car I did eleventy years ago I recall we put a leaf front driveshaft in it.

You don't have to use the handbrake drum, when i changed mine i just changed the rear flanges over as well and used my normal rear drums as the handbrake. Might be different on a coily but.

Hi All,

Thanks very much for the info, I am going to try the 1Lt case with the front shaft from a leafy and use existing handbrake from rear drums. Hopefully works out ok.

f you run the fron leafy shaft..wont you have to change the front diff flange too?or at least get the shaft moded?

Ps let us know how you go as I will be doing this mod in the near future maybe some picks??hehe

WT flanges are the same as coily, coily are just threaded, so you can use the coily bolts to bolt on the wt flange
