KD Intercooler on the 1500 8 lug

[Kennedy]

Guys, I'm looking for anybody running my Intercooler on a 1500 with 8 lugs. I'm just wanting to verify my belief that the 1500 8 lug is the same as a 2500 8 lug for all intents and purposes. We know that the 1500 and 2500 6 lug trucks have a different frame and the cooler wil not fit without excessive mods. These trucks also have the S engine where the 1500 and 2500 8 lig trucks have the F engine. What a mess...

The only 1500 series with a 6.5TD will be the Suburbans that have 8 lug wheels, no trucks are included in this.

I'd bet some $ that the IC would fit the 1500 Series 8 lug Suburbans as mentioned.

This isn't true. There are many 1500 series, 6-lug trucks with 6.5 TD's. These are the "S" engines. There were several at the Rendezvous in MI. The Blazer/Tahoe is an example. In fact, Tim Outland has adapted a KD cooler to 1500 truck...

John, Brian Johnson has a 1500 Suburban with VIN F engine and 8-lug wheels. He can measure the frame rail height and report that. I can measure mine and report that for comparison... if no one else steps up.

I think the frame on Brian's Sub will be smaller than mine, but could be wrong. I think that's why you can only get 8050 lb. GVWR with the 1500 Sub but can get 8600 GVWR with a 2500.

I edited my post, I forgot the key piece of information, that the only 1500 series with 8 lug wheels will be the suburbans. Meaning, there were no 8 lug 1500 series vehicles with the 6.5 in the truck/tahoe/yukon/blazer.

I think the difference here is the rear differential. the 1500 Subs use a Semi-floater, the 2500 the full-floater rear axle.

I've got a 1500 6.5 with 6 lug wheels sitting out in the parking lot as I type in a Tahoe...

I'm 99% sure that the kit will fit the 1500 8 lug. We've always used the 8 lug feature as a measure, but there's the 1% of uncertainty.

Good Day!

"He can measure the frame rail height and report that." Tell me where to put the ruler/caliper/etc, I'll see what I can do.

"I'm 99% sure that the kit will fit the 1500 8 lug. We've always used the 8 lug feature as a measure, but there's the 1% of uncertainty." Well, John, just send me the complete IC kit, I'll install it & see how it goes, & I'll return it to you right after I finish making sure it works real good. ;) (Please don't make me tell you that of course I was kidding.)

Blessings!

Good Day!

My offer stands - just tell me where to put the ruler/caliper/etc.

It's a real shame we didn't think of this when RJ visited on his way back from the Pull: His 2500 Sub was in my driveway, next to my 1500 8 bolt 3/4-ton-everything-except-semi-floater-8050GVWR Sub.

Blessings!

A guy would almost want the two side by side to verify as I don't exactly know what interferes on the 6 lug trucks myself. Tbogmirep recently acquired a 150o 8 lug and has a 2500 6 lug to compare it to so I hope to have him check it it.

Thanks for the offer, may still need to follow up.

Good Day!

Then it's REALLY a bummer we didn't look when RJ was here - two houses down from me is a 6-lug 2500 extended cab pickup.

Blessings!

On the to do list John give me a shout on the phone if you want I'll PM you the office number. I've been busy trying to get the Burb to run right, I think I have it figgerd out, or at least wherin the problem lies. Bad ABS control or data-link wire to it, when plugged in Security-ABS lights were on, no communication with the PCM & scan tool. Lack of comm link would cause the APP to fault and truck to stumble at 45 mph, I think from PCM APP signal going low in limp mode (protective mode) when I would get above 45mph or so, and APP request was high with my pedal to the floor trying to get the truck to maintain speed.

Once I let off the pedal and APP demand matched APP actual feedback I was able to drive just under 45 without dropping into limp mode again.
