Magnetic Ride Control

slowfive0 · December 2, 2016

To add to this subject. I have a 2015 Sierra 1500 Denali and I agree, the 6.2 / 8 spd combo is outstanding!!!

The ride was great too, now not so much. At around 50-60k, one of my front shocks started leaking. Dealer quoted me a ridiculous price to replace it (I have the extended warranty so price was my ded plus some % of part based off of miles, etc). I was having other work done so I don't recall the exact amount quoted and the dealer also thought it had standard shocks on the front and MRC only on the back. Given the price and the fact that shocks should always be replaced in pairs I was like screw it. I'll replace both fronts with some Bilsteins or something for a litle more money but at least I'll have replaced both units. Well ride gets worse and I start looking for shocks and realize they aren't available because my truck DOES have MRC on the front (easily confirmed by the wire coming out of the top of the shock lol).

So, fast forward to today and my truck has 78,000 miles (ride is absoluted horrible now). Took truck in and now three shocks are leaking! Price (probably retail) for the three shocks is like $2800 but GM is willing to help me out a little. Quoted me $1500 to replace the three. Well you know the 4th is right behind the other 3. So "if" I can get them to replace all 4, I'm sure the price will be around $2000. WTF! Shaking my head. I guess shame on me for wanting the MRC in the first place. Definitely, a negative from my perspective regarding this experience. I'm looking at on-line pricing for these MRC shocks. Gmpartsdirect looks to have them for about $345 a piece! So @$1400-1500 in parts alone plus labor unless I do them.....sheez!

Expect repairs fellas around 60-80,000 miles. Note: My truck has never been off road and is driven in a mixed type of driving around town primarily (Detroit metro area). And I baby it. I look for the potholes and avoid them if at all possible. I ease over speed bumps and into my driveway, etc. Oh well........Good luck

That's crazy expensive for some shocks. Oh well. Only money. Quit feeding one of the kids for the next year...ought to about cover them right?

I got the denali because I wanted the MRC, honestly, I don't find it to ride much better than my old tahoe. My family seems to think it's the best riding truck on the road and that it's much better than the old tahoe. It does tow much, much better. That alone is worth the price of the truck to me. Now I can find fishing holes further away and not dread towing the boat back home.

Lol. No doubt!

Ride is good but at 60-70k miles not worth the money. On a Cadillac CTS-v yes, truck no. Live and learn I guess.

I wanted to try the MRC but probably would have passed. It was the only 6.2 truck on the lot and I made an impulse decision cause I wanted it now. Honestly, I should have ordered a trailer tow package 6.2/8-spd combo in the SLT and saved a few bucks like I was planning.

And last, why does GM have to be so GREEDY. Please offer the 6.2/8-spd with and SLE!!!

To add to the above, would love to get the 6.2/8-spd package in a regular cab/shortbed truck. Add an SS option and I would be in heaven ?

Would be pretty cool to have the 6.2, blown, in a factory SS regular cab truck.

Yes it would!

To add to your earlier point about towing. I towed about 7,000lbs with my cc/sb/4x4 a couple of years ago from GA up to MI. I was in a hurry so I didn't baby and it was a monster for a gas truck! Averaged 13.5 towing 70-75 easily. And this was going up through the mountains. I was passing cars going uphill with ease. I can't say enough how impressed I am with this package.

Took it to the track to see what it would do and it went 13.70's at 99mph!!!!! It was hitting the veh spd limiter hard just before the stripe! That was in 50^ ambient temps from what I recall. Pretty impressive. My average mph display on my trip odometer is 35mph (mixed driving) and I average 19-20 under those circumstances. Best average was 21.3 for a tank but had to drive very easy. I averaged 19.2 for over 10,000 miles. 20.2 average is super easy too. It's a great package.

To put this same Powertrain in a lighter chassis........heaven!

Figured the MRC shocks would probably die at around 60 or 70k but hopefully as the MRC becomes more common, the aftermarket will have some good cost effective MRC shock alternates in place before too long.

The 6.2 8spd is a sweet combo even with the std 3.23 rear end. Still averaging over 20mpg at around 10,000 miles mixed driving with lots of remote starts not trying for great gas mileage it just does it................................

I think GM has a patent on that technology so unfortunately not likely. Could go to regular shocks I suppose but obviously defeats the purpose :-(

You must be older like me (I'm 46) cuz everyone I know that has these are younger and don't get the same mileage lol!!!! I remember those days. Gas pedal was either on or off lmao!

slowfive0 · December 4, 2016

These company's know what they are doing (unfortunately). They know a lot of us would buy a stripper with the bad ass Powertrain. I don't need all the gizmos, just want the high end Powertrain. Makes them tons of money that way.

For my next truck, i'd like to buy a high mileage Silverado SS and swap a donor 6.2/8-spd Powertrain in it! I loved my SS but it's mileage sucked! As much as that would be cool and Cheap!

I know I will succumb to my "want the newest" gadgets/gizmos and buy a new 2019/2020 model. They are supposed to be a lot lighter, start/stop technology, new generation i.e. more efficient engine, 10 spd trans , Etc

I won't be able to resist lol!!!

Yes I am older than dirt, but I still enjoy a good jack rabbit take off and high speed run occasionally. I had to reset the speed limiter to 125 everytime I went to pass someone the silly thing would cutoff at 98. It is still pulling real hard at 125 not sure what it would do with proper driveshaft and tires..... just an amazing truck I absolutely enjoy driving it makes my OLD face break into a grin everytime I turn the key

1,321 miles, avg 19mpg. Only time I drive on the highway is with the boat in tow. I'd like to think I'm not too old..35, but I've always driven like a grandpa.

Will be looking for a hotrod at some point in the future, may not get the same mileage out of that. 6.2/8sp combo in a late 70s c10 would be cool.
