Re: Got some new wheels: Boss 338's in 20x10 and 20x8.5
Here's my freshly painted 1971 2wd blazer rolling on 338's with a 1" rotor in the front... A big thanks goes out to Lolife99 for informing us on the 1" rotors!!!!
I purchased a set of belltech's 3" drop spindles for 1" rotors and it fits great. My sizes are 20x8.5 in front and 20x10 in rear.. I upgraded all the ball joints and tie rods to the 73-87 also with a ART front end bag kit and ART arms.. ( cool ride ) I ended up getting a rear coolride kit also... very nice stuff wirth the $$ IMO.. Here's a couple of Now and before tear down pics.. |

Re: Got some new wheels: Boss 338's in 20x10 and 20x8.5
Wow!
That chassis is beautiful! Zammer did you have to cut the end of the spindle down? Or grind a radius on the edge of the front rotor hub to get the caps to clear? Do you have a build thread on your blazer? |

Re: Got some new wheels: Boss 338's in 20x10 and 20x8.5
Hey thanks Lolife, I wasn't planning on going right down to the frame but... i'm pretty picky about stuff - a bit much sometimes, but i'm glad i ended up there as it turned out good and its nice bolting on stuff to a fresh frame
.. No, i didn't have to cut the end of the spindle down at all.. are some guys needing to do this? I don't have a build thread but i was thinking of getting one going, I finally figured out how to post pics properly.. ![]() |

I think the guys with 1.25" specific spindles are required to do this. Did you grind on the rotor hub at all? |

Re: Got some new wheels: Boss 338's in 20x10 and 20x8.5
nope, i haven't had to grind the rotor hub at all yet... I would doubt i need to at all..
Bearings and dust caps went on good and the wheel bolted onto the rotor fine.. |

Re: Got some new wheels: Boss 338's in 20x10 and 20x8.5
Been looking for wheels and found this thread today, I guess I need to take the
Coy's off so I can see if the McGaughy's 13" brake floating hub will be an issue? I really want to put the Coy's back on the 81 and get these for the 72 so I am in for a group deal hands down. Zammer do the 10's fit well on the Blazer rear? ![]()

Re: Got some new wheels: Boss 338's in 20x10 and 20x8.5
yeah the 338's seem to fit good in the back on the blazer.. I haven't had the body back on yet to see if i need to put spacers in or not.. I have to do some rear fender work anyways so i was going to widen them if needed..
I will measure the rear tires end to end for you when i get home from work tonight.. then maybe you can compare track widths.. your blazer chassis looks great! looks like near the same gloss as mine. sweet. kris |

The only problem I see with the 20x10's is they only come in 6.25" backspace. I don't know what BS you're running on those 22x9 Coys,... but I'm pretty sure you will need a spacer to put these Boss 338 20x10's on the rear of your blazer. Last edited by lolife99; 01-27-2010 at 12:50 PM. |

Re: Got some new wheels: Boss 338's in 20x10 and 20x8.5
I wonder why they don't offer a 5" BS. Seems like that would be the most common...

I'm not really sure what Boss was thinking. Seems like they design a wheel and only offer one backspace per design. Last edited by lolife99; 01-27-2010 at 03:28 PM. |

Re: Got some new wheels: Boss 338's in 20x10 and 20x8.5
Your right, mine are perfect, any less they would rub the lip on the bed side, any more and they might pose a problem with tire rub on the leafsprings.
Here is how i look at the whole situation, these are AMERICAN made wheels, quality is great, and price cant be beat. I bought these knowing i would need a spacer to make them fit on the front, but once you see a set in person, you will want a set. |

Re: Got some new wheels: Boss 338's in 20x10 and 20x8.5
Ok,... a little update from me.
I wanted to post pics of my 338's mounted. I hammered the dust cap flat, just in case it hit. (now I don't think I would have had to). The clips on the plastic Boss wheel center cap still needed a sliight trim. The picture shows all of them trimmed except one. (To show how little needs to be removed) Everything fit fine after that. I did put a small dab of silcone on each clip, just for the heck of it. All of this trouble seems worth it (to me) to get cheap wheels,... but it's far from a "bolt on" wheel. Another issue I recently found,... is the recessed holes for the lug nuts are really small. They may be fine for a 7/16" lug nut,... but the 1/2" lug nuts required for our trucks,... seem to make it really tight getting a socket inside the hole. I used a (3/8 drive) 13/16" socket and it was still hard to get the lugs inside the recessed holes. |

Re: Got some new wheels: Boss 338's in 20x10 and 20x8.5
love these wheels so worth a little extra work.
Can anyone please measure total outside width of thier rear wheels, I think I got too big of a real tire. 315/35/20...12" wide. worried it will not tuck if laid out??? I got 73" total width. is that cool? Last edited by Ronm909; 01-28-2010 at 10:47 PM. |
