I saw the RCV setup. they have a nice product.

New axle will have non standard inner shafts. quick lead times on custom shafts and outstanding customer service are what's leading me to Branik.

Understandable.

What's the max steering angle if the big bells?

43° with 40sp shafts

What's stock/factory steering angle?🤔

SteveJenkins · Sep 10, 2023

Will I have to run a spacer or will most 8x6.5” wheels fit over this?

gathering more basic info...

what 9/16" wheel studs is everyone using when they redrill the units to 8x6.5? and what size do the new holes get drilled to?

I drilled mine with 15mm annular bit.
Pressed the stock studs back in.
Same threads as my 14bolt.

making it look easy! my rear axle has 9/16 studs so looking to run one lug nut.

first step looks like it's for the rotor. second step looks like it's for wheel. what did they mic out to?

50 degree+ with the 1550 shafts.

The actual turning angle of the axle in the truck is a lot less than that obv.

I’ll have to double check after work. I think the outer step is 4-7/8”.

Didn't we determine earlier in this thread or maybe another that the stock knuckle will lock you in at 38°?

I don't think so

Well it was a guess at 36°, so i was wrong, but have a confirmation of 42° when grinding the stops.

Bebop · Sep 13, 2023

Factory C.

I'm using Spicer ones which is probably why they travel further.

what can be done to gain more steering angle out of the 05+?

See what hits and take your grinder to it. 1550 joints will support more steering angle than most people can realistically package.

Grinding.

Have you ever tried to package 50deg of steering ? It's really hard.

This is literally my life right now.
33" wide front frame
70" wms
40" on 4.5" bs wheel
Even with straight front links I can only get about 38* when the tire contacts the frame.
Adding to the wms or wheel changes are the only things I could change to achieve more.

99-04 OEM inner c, knuckle and unit bearing vs 05- up OEM inner c, knuckle and unit bearing.
NOT perfect because I have a high steer arm welded on the 99-04 knuckle and no wheel studs in the 99-04 unit bearing. I am not removing wheel studs or cutting off the high steer just to get a better comparison. :flipoff2:

2010 knuckle with window above lower BJ.

99-04
bearing bored for 35 spline 20.8 lb - 9.43 kg
inner c 15.0 lb - 6.80 kg
knuckle with high steer 30.0 lb - 13.6 kg

Total 65.8 lb - 29.84 kg

05 -up
bearing 23.8 lb - 10.79 kg
inner c 21.0 lb - 9.52 kg
knuckle milled for B/K high steer 26.6 lb - 12.06 kg

Total 71. 4 lb - 32.38 kg

Difference of 5.6 lb - 2.54 kg

What length stroke DE ram and steering knuckles are folks using to get 40 plus degrees out of the steering? I’m swapping in a 05 axle in place of the 04 and going full hydro at the same time. Looking at the PSC 2.5, 8 or 10 inch???

pennsylvaniaboy · Sep 14, 2023

you will definitely need a 10" ram unless you some how get the ram to have more effective throw that the tie rod.

Bebop · Sep 14, 2023

Has to deal with steering arm length. Not necessarily just ram length.

gozuki · Sep 14, 2023

I used a 2.5 x 10. I need to make (qty 2) stops around 1" thick, so realistically you could probably get by with an 8" stroke

I'm using an 8" stroke on mine with weaver arms. Mine goes a little past lock to lock so I'm going to have do a little grinding...i haven't fired it up yet, still in construction phase :homer:
