BD's 4 wheel low lockout.

[Gonzo 1066]

Just finished installing BD's new 4X4 low lockout on my 2001 3500. Appears to be high quality parts. The instructions were good and installation went very good #ad
. The unit seems to functon very well= no 4X4 in 4X4 low if the switch is on. It will be very nice to be able to back up the trailer on hard surfaces in 4X low without the front axle engaged. I carry a truck camper 100% of the time so the weight really ties the tires to the ground. I will post more information as I get miles on the unit.

RG,
Would you mind giving more info on the BD kit? What comes with it, how it works, etc? Is it only a solenoid that prevents vacuum from reaching the front hubs? This is a future upgrade for my truck and I'm looking for possibilities.

I have been looking at the different 2WD Lo kits that are available. The BD looks OK. Anybody have any experience with the cable activated kit from Willards, 4x4 Posi-Lok. There was a small press release on page 128 of the #30 TDR.

bumble,

I also have the BD 2-low kit. I have had it for about 6 months. It works well. As you suspect, all it is, is a solenoid that prevents vacuum from reaching the axle disconnect mechanism. It comes with an industrial soleniod valve (same one they use for the exhaust brake), a nice mounting bracket, a lighted switch with a nice legend plate, and wiring. I mounted mine in the plastic housing next to the shifter.

I think the questions have been answered. But here goes. There is a selonoid that keeps vacuum from engageing the front axle. It is not just a simple cut off switch . Aparently the early simpler vacuum routing did not always release the front drive. Quality of the components seem excellent. Should be VERY nice for that blind side, up hill, long trailer backup. I would hope the price will be covered by the convience alone to say nothing about the saveings in clutch wear.

The original BD 2-Low kit worked very well at cutting off the vacuum from the applied side of the 4WD axle actuator but did not apply vacuum to the released side to keep it released... so you had a diaphram flopping around in the axle actuator...

It was brought to BD's attention that the front axle actuator could possibly jump into 4WD while going over a large enough bump (tree stump or rock) and cause the diaphram to slap into the 4WD for a split second, long enough to scare the C$#p out of the driver but not do any damage as the speed at which it is used is very slow.

Needless to say, BD and their engineering department decided this was not acceptable and went to task to prevent this from happening...

BD is now shipping a 2-LOW retrofit kit that upgrades the existing kits to control the front axle actuator off or on, in any transfer-case position so that if the front axles are engaged, the '4WD' light on the dash is illuminated thus indicating to the operator the position of the 4WD actuator.

BD is presently shipping these retrofit kits directly to their dealers and distributors and end users, if you need more info or have a BD 2-Low kit please email me and I will forward info to any of you that request it.
