Yes, 5 on 4.5" for drum bakes. I've heard the very latest ones had disk brakes on the rear and 6 lugs, but I've never seen one. Bob
I'd rather not run adapters, but sometimes they're needed. I run them on the rear of one of my cars to get tire clearance inside. They're billet adapters, and I've pulled the wheels a couple times each year to check if they are staying snug. So far I've never found them even slightly loose, and they've held up to hard launches with no problems.
There are a lot of guys here that have used adapters without any problems. Do some research on steering and suspension theory and scrub radius and the effects on steering and braking and decide if you still want to use a adapter or spacer. I have seen wheel offs, premature bearing failures and excessive tire wear due to the use of spacers, adapters and positive offset wheels.
Yes, but no one ever mentions anything about bearings when talking about wider wheels with a deeper offset, yet it always comes up with adapters or spacers. I wonder if anyone has done a study on bearing life expectancy with offset wheels vs. stock. Whatever stock is.
I agree totally. Any time you move the center line of the wheel further out you are shifting the load away from the inner bearing and putting more load on the outer bearing. It doesnt matter if it's a deeper offset wheel or by a spacer or adapter, the geometry has been changed. You are also changing the tires scrub radius, which has an effect on handling, braking and tire wear.
Just for discussion here, apply this theory to a 1 ton dually front wheel. For those not familiar with it. There's a 6" adapter to move the WMS out and then a 6" offset rim to bring the tire back. Tire is in normal location but the bearing sees much more leverage.
No problem, and thats what I used them for....8" maverick rear in my '34 cabriolet project with old nice patina-ed steelies.
The reason they use a spacer on the front of a dually is so that you can rotate the tires front to rear and I am guessing it would also allow for bigger brakes . The net effect on scrub radius is zero as the tire centerline is the same as single wheel truck. I would agree that there would be more leverage on the outer bearing but the factory engineers that into the size of the bearings and spindle. Much larger than what's on a passenger car.
I am going to have to use 3/4" billet machined hub centric spacers to allow my stock 16" 1940 Willys wheel centers to clear the rear brake calipers - the lip of the ventilation windows on the wheel center hits the caliper. I will be using longer ARP's finest loger wheel studs and really do not forsee any problems - engineering your ride properly makes a difference....
I run billet wheel adapters on my Willys sedan and use the best quality nuts I can find - Grade 8 works for me. I re-torque them a couple of times a year. A note of caution though - a lot of the swap meet stuff have metric wheel nuts with the adpaters and the thread pitch is very close to a 1/2-20, but the nut will rock a little on the 1/2-20 thread. Check this before you torque the nuts down as they may not torque fully. I use 90 ft/lbs as a rule of thumb. The metric nuts should be marked, so scrutinize them....
I don't believe you're correct about the additional stress on the bearings due to leverage. The only additional stress the bearings will see is whatever additional weight the spacers and wheels may add.
If you want to run Steelies ... like this WHY NOT just purchase new rims ? There are more than 3 or 4 companies making the STEELIES with dual wheel bolt patterns. 5 on 4.5 ( Ford ) and 5 on 4.75 ( Chevy ) http://www.rallyamerica.com/Gennie.html I copied this from above.
