Control Arm Joints

Mon, 17 Jan 2022 19:40:45 +0000

I've looked at so many end joints over the past few months that I've almost gridlocked myself trying to figure out which to use. I ended up going with these from TMR Customs and the tried and true Johnny Joints. Originally I was going to use the TMR joints on both ends of my control arms, but the diameter is too damn big to fit into the Motobilt frame brackets. They measure 3" dia and the JJ's are 2-1/2". So the plan now is to use the JJ's at the frame and the TMR's at the axle. In hindsight, it might be a good thing that the TMS were too big so that I have the JJ's at the frame for a little cushioning. The TMR's have replaceable bronze bushings so there isn't any give - see parts in rebuild kit.

Seats!

Tue, 13 Feb 2024 17:38:26 +0000

Jeff and I have been talking.

Do your seats actually fit you?

Been doing some measuring. Most seats have the shoulder belt holes at about 23-24" above the bottom pad.

Many of us are over 6' and this causes our shoulders to be about 26-28". Plus the head rest is about useless.

Doing some research I found that the shoulder belt holes should be at or slightly above your shoulders so that you don't compress your spine in an accident.

I haven't been able to find any seats that have more that 24" without going full custom. $$$..

What have you found?

Winch Lines!

Tue, 06 Feb 2024 17:20:58 +0000

I need to replace the synthetic line on the buggy before the trip.

From what I have found I need 3/8" line... 80-85' long.

I have been looking at a few options.

The first one is a local company. Masterpull.

They offer three different models of synthetic rope. All made with Dyneema SK75. The differences I can see in the models is the protective outer layer and the strength ratings. They range in price from $325- $605.

Superline XD - $605

https://www.masterpull.com/superline-xd-winch-line-3-8-9-6mm/

Core Diameter	5/16" (8 mm)
Overall Diameter	3/8" (9.6 mm)
Minimum Breaking Strength (MBS)	21,700 lbs (9,840 kg)
WLL 2:1 Safety Factor*	10,850 lbs (4,920 kg)
WLL 4:1 Safety Factor*	5,425 lbs (2,460 kg)
Recommended Winch Rating	8,000 - 12,000 lb (3,630 - 5,440 kg)
Core Material	Heat-set Dyneema® SK75 synthetic fiber
Cover Material	Black Dyneema® SK75 synthetic fiber with reflective tracer

Superline - $555

https://www.masterpull.com/superline-winch-line-3-8-10mm/

Diameter	3/8" (10 mm)
Minimum Breaking Strength (MBS)	29,700 lbs (13,470 kg)
WLL 2:1 Safety Factor*	14,850 lbs (6,735 kg)
WLL 4:1 Safety Factor*	7,425 lbs (3,370 kg)
Recommended Winch Rating	10,000 - 16,500 lb (4,540 - 7,480 kg)
Material	Heat-set black Dyneema® SK75 synthetic rope

Classic - $325

https://www.masterpull.com/classic-winch-line-3-8-10mm/

Diameter	3/8" (10 mm)
Minimum Breaking Strength (MBS)	23,500 lbs (10,660 kg)
WLL 2:1 Safety Factor*	11,750 lbs (5,330 kg)
WLL 4:1 Safety Factor*	5,875 lbs (2,665 kg)
Recommended Winch Rating	8,000 - 12,000 lb (3,630 - 5,440 kg)
Material	Dyneema SK75 synthetic fiber

The Superline looks the strongest but the Superline XD looks to be more durable. All three are above 20,000# MBS.

The next options I found were through Warn.

WARN Spydura Nightline Reflective Synthetic Winch Cable Rope -$289

https://www.warn.com/spydura-nightline-80ft-synthetic-rope-assembly-with-hook-102560

Not much info on this outside of the 12,000 rating.

Spydura Pro Synthetic Rope - $407

https://www.warn.com/spydura-pro-synthetic-rope-93120

Little more info on this one.

Spydura Pro synthetic winch rope using Spectra® 1000 is heat treated offering the maximum in tensile strength and load bearing capacity. The compacted diameter prevents sand and dirt from penetrating the fibers and extends the life of the rope. Coated with high temperature urethane, equipped with a temperature resistant sleeve on the first layer and a ballistic nylon sliding sleeve, Spydura Pro synthetic winch rope provides extreme protection against heat, wear and abrasion.

Rated for 16,500.

	Anyone else you can think of to look at? I haven't decided yet on what way I am going to go. I feel it's down to the Superline XD, Superline, and Warn Spydura Pro.

Switch panels

Thu, 03 Mar 2022 16:10:03 +0000

Thinking about replacing my old Painless Trail Rocker with something with more capacity and a more modern interface.

Looking at the Switch Pros RCR-Force 12. It’s expensive so I’m interested to hear if anyone has experience with it. Is it worth the money?

Other recommendations? Most panels seem to have eight switches, which isn’t going to cut it for me once I move to the new axles with ARBs. I’m already tapped out with lights and other accessories.

Maybe just get two Apollointechs or other eBay/Amazon made in China panel?

Seats & Harnesses

Fri, 15 Sep 2023 15:26:51 +0000

My Jeep is at the fabricator to have a cage made, so I need to pick out seats and harnesses. Top choice just from reading is the PRP Daily driver seats. Though I'd like to hear what you have or what you want to get. Fabric choices, etc. Reclining or not?

5 point harnesses or 4?

Also, the fabricator suggested not bothering with reinstalling the factory seatbelts. I have read many say to keep them for DD and street use because the harnesses are just too restrictive, can't reach the radio or turn to look over your shoulder, etc. I did tell him I want to keep the oem seatbelts.

I'm going to look for a vendor that has some so I can try them out, see what's comfortable.

Helmets

Tue, 19 Sep 2023 18:10:31 +0000

Anyone using a helmet? My roll cage is going in, so figure I should have a helmet. Probably will only put it on for more extreme obstacles, but thinking I should wear it driving to and from the trail as well since a high speed accident could also bang me around a bit.

I was looking at the Axel helmets. Seem decent for the price, not too restrictive. What are you guys running?

Steering ram clamps

Sun, 03 Sep 2023 15:49:55 +0000

I know many have had issues with the tie rod clamp for the ram.

I recently found what seems to be a good option and wanted to share it.

I have NOT tried it personally, nor do I have any connection to the seller, but it looks like a solid unit, and addresses many of the problems found in other units.

Let me know your thoughts.

On board welders

Sun, 02 Jul 2023 19:44:24 +0000

Premier power welder is made in Yucca Valley California. They also known as ACE alternator. Both companies make a great product. There is other companies like Bun trail welder and Lagace welder that have great wire feed welders that work with premier power welder.

this was my first install. Once I got my light control I had to change the location.

My second and final location.

this is the Lagace welder that works with Premier power welder. The gun is much smaller than Bun trail welder.

Tie rod ends

Mon, 01 May 2023 01:46:17 +0000

I feel like I’ve been seeing a bunch of social media posts recently about broken tie rod ends. Mostly the Apex ends like RPM uses, but also a few Rare Parts ends like Fusion uses. I guess some of these companies are pretty good about warranty replacements, but you still could have a pretty bad day and maybe lose several days of wheeling if you break one on the trail. Anyone carry spares? I just added left and rights to my trail kit. Steer Smarts (Artec). $200 each. 😣

Gear Oil?

Fri, 17 Feb 2023 14:32:47 +0000

For those of you running ARBs what gear oil brand, weight, and types (Synthetic or non-synthetic) do you prefer?

Yukon Super Joints

Thu, 26 May 2022 01:48:28 +0000

Anyone running them? Tips for install? Getting reading to replace my front axle shaft joints with these.

Brake Lines

Wed, 16 Feb 2022 16:38:19 +0000

So with the builds that many of us have going on I am going to want to rerun the rear lines to work better with the new set up. That being said, looking for input as to type of lines folks are recommending. I have seen many say the flexible poly lines are perfectly fine, stainless lines are preferred, or the copper brass is the way to go. In my mind, I want hard lines where possible and flex only where I have movement. I am sure I can salvage a portion of my lines but thinking I may just want to redo these as I will need to completely remove the rears to accommodate installation of the front towers. Look forward to peoples thoughts.

Thoughts on these pinion guards for a 14b?

Thu, 10 Feb 2022 02:00:46 +0000

Definitely see the value, but also see where this could get bent up into the yoke on a hard hit. Course that hard hit could also screw up your DS/Yoke/U-joint straps.

IDK. Thoughts?
