Works like a champ

The spindle worked great on my K20, surprisingly there was no damage to the spindles (I ordered 2) because of the packaging. I can't believe G2 would put a $100+ product in a box and ship it. No kidding, it was a spindle and a box. There were no peanuts, paper, thread protectors, bubble wrap, not even a plastic bag...pathetic.

Top Notch Product

Couldn't ask for a better replacment part. fully satisfied with it. only problem i had was getting the correct one.. part was listed incorrectly on 4wheel parts i contacted G2 and got Correct part # that i needed i had already installed the new ones on truck before i noticed they were for pre 76 i needed 77 up. 4wheel Parts took them back since they had listed them wrong but i was out inner axle bearings and time shop bay was blocked parts sent back on 10-16-12 had to call to get them to process the return so correct ones would be shipped received correct ones on 10-24-12. Charged me for the differance in price.. they did cover freight but could have been faster than ground from Cal.. to TN

I have an '84 Chevy K20 spindle with B38428M1R58 0614 stamped on the bolt circle rim, will this part work?

Asked by USMC-Goose from on

Hello Yes this is the correct part for your K20 it works on the 1977 and newer trucks. You will need the D/S 706527x which is the inner spindle bearing and seal. Thanks
