Cucv upgrades.

What are your favorite cucv upgrades?If we keep it sweet and simple it will be easier for people searching.

 

[rsh4364]

Ill start with the doghead starter relay mod.

 

[Ackevor]

Glowplug Relay resistor bypass

Depending on your uses, an overdrive transmission.

 

[rsh4364]

cucv spin on fuel filter.

 

[rsh4364]

cucv headlight wireing harness upgrade

 

[CUCVLOVER]

Spin on fuel filter, oil pressure gauge, tachometer, and straight piped exhaust. Resistor bypass, power ports in cab, And lots of off road lights. Stereo with plenty of speakers

One I have not done are engine, trans, and exhaust temp gauges. Then turn up the injection pump.

Great thread thanks

Overdrive transmission, preferably a 4L80E using aftermarket controller. In the future..yes to the lockup torque converter and 25% OD.

Air conditioning has been my favorite. My SECM needed a rear view camera, that has saved my bumper. Civy hitch.

I'm still rocking the original fuel filter, this is a two stage with water indicator. Nothing wrong with the design, in fact it is better than a single stage spin on.

Tilt steering column with intermittent wipers and a serious stereo, amp and speakers setup.

Crane Axle urethane King Pin Spring Eliminators.
Upgrade gauge of heavy-current wires like those carrying alternator current, and the big grounds.
33" tires (require no lift)
Banks Sidewinder
LED lights
Winch
Serious rust treatment/prevention.

Don't forget to replace the harmonic balancer

Maintenance issue

And just as important as the DH relay mod, etc. already listed

What about Horse head relay? I laughed when I seen this is a box of CUCV parts I bought from a guy that sold his M1028. He had a lot of NOS stuff and this was the funniest part I seen. The horse head relay 1st Cav. Most of the parts he had were door parts and some brackets for alternators and starters. Since I use these relays I will add it as a spare in my parts. It is an original GM one and still works I plugged it in and tried it. Great find. It did give my Son and I a great big laugh.

• H4 headlights
• Headlight harness
• Sound deadening (inside, underhood)
• Bigger fuel tank
• LED lighting on everything but the headlights (exterior, blackout drive light, dash-board)
• Tint
• AM/FM radio-stereo with an aux jack.
• Group 31 batteries
• Higher output alternators (>150Amp, better for fast charge on short errands)
• Spin-on fuel filter
• AC60G, with 24-to-12V regulator replacing ballast resistor
• Manual glow override switch as a backup (with a working glow controller as a primary)
• Better horn (I mean come on... )

I got to ask. Why not LED head lamps? Am I seeing so much better at night with them that I am missing something? I had to ask why?

 

[rsh4364]

tim292stro do you have a write up on 24-to 12v regulator set-up.which replaces the ballast resistor reducing volts to GP solenoid?With picts.

 

[Cantos]

- H4 Headlights
- Hella 2x 2tone horn
- transmissionoilcooler
- dh mod
- manual golwing
- cb-radio with military antenna
- flowmaster super 44
- watertemperature gauge
- tinted windows side and tailgate
And many ideas......

I will be doing this to the new M1009 when I'm past some other issues - it'll be in my thread for that truck but I'll link it back here.

Material cost is about $260, so it's not a "cheap" change - but most of my projects can be priced around $250 each, which makes it easier to do installments

Where can you find higher output alternators, I have actually been looking for isolated ground 150Amp alts.

 

[tim292stro]

You have to go to a different case (like 28SI), or have them re-wound. For the M1009 I'm talking to a vendor who is custom winding me a pair of 250Amp isolated ground 28SI alternators - I never expect to run >200Amps ever (VERY hard on a single belt), but the extra design headroom means I won't be stressing the components as hard. Really the rectifiers are the part I worry about the most in an alternator - getting an alternator that can do 25% more than my expected peak load means it'll never be in danger of burning up (and it'll be fused for 225A).

For my XM1027 build, I'm using a MRAP 450A 28.8v alternator.
