I'm looking to level out my '11 4x4 silverado and debating between the Bilstein 5100 ride height adjustable or a complete coilover kit. The 5100 is just a shock with the stock spring just preloaded with a max lift of 1.75". Fox offers a complete coilover kit (spring, shock, reservoir) but at 3" of lift. I do believe that there are other companies that do offer complete coilover systems, just don't know who. I know the 5100 are no more then $300, but some coilover kits are easily over $1,000....lol, but is there any significant benefit between the 5100 and a complete coilover kit? I'm just having a hard time compressing the stock spring and not causing any wear/damage vs a whole new system.

With the Bilstein 5100's the spring rate stays the same, you just move the spring up on the shock body via clips in the body. Ride should stay the same and you can still get the truck pretty level without putting too much stress on the other front suspension components. If you run the replacement coilovers at the 3" level you actually have more of a chance wearing suspension components out because your CV, balljoint, and tie rod angles will all just about be maxed out. Spend the extra money if you like, but if you're looking to level the truck and keep decent angles I would go with the Bilstein's. Icon Vehicle Dynamics (what I run) and King also make the complete coilover leveling kits, but are all priced competitively with Fox for the same product.

ps. love your white truck, bad ass. Yeah I was def. leaning towards the 5100 but just wanted to know all my options. I was also planning on doing an Add a Leaf to gain the factory rake back (i like the rake look & haul alot and dont like the sag), but with raising the rear like an 1" or 2". With the truck being at almost same factory rake with AAL/5100 but sits a little higher, does that correct the angles and not cause the premature wear on my suspension components?

The 5100's on the highest setting will not be that bad on your angles up front to cause noticeably faster wear on your stock parts. As far as raising the rear of the truck to get the rake back, you may also check into doing the GMT800 block which is 2" vs the 1.25" block of the stock GMT900 block. It will net you .75" of lift and most definitely ride better than the AAL will.

hmm i definetly look into the 2" block. in a different post about control arms regarding cognito. they offer the 5100 adjustables with cognito control arms. are the control arms worth it? if so should i stay with cognito or a different brand?

IMO with just the Bilsteins I don't see why you would need to add control arms. If you run into the truck bottoming out on the droop stops when the wheels drop then yes you may need them. But for the most part with just 1.77" of level up front it's not an issue.

as far as "brand" I have rancho on my truck from the factory....they are quality from what I can tell...not a whole lot of difference from my 2011 silvy with bilstiens (standard z71 suspension w/ leveling kit)

      HighMileage oils or stay with Dexos 1 ?

      By Z45 · Posted

      dexos began as an effort for GM to control the oil change market because the Quick Lube Industry was eating into dealer service department profits big time. So they attempted to get other oem’s to develop standards as well and that would make it hard for Quick Lubes to compete because all the oems would be different. GM faced lot of industry push-back, mostly the quick-lube industry and they went to licenses. Still GM it making a ton of money (est'd 30-40 million in 2025) off the license structure as they charge a hefty fee to get oil tested then require a royalty on ALL gallons sold applicable to GM vehicles.

      Those are parts changers. It can get expensive though. I was a mechanic for 30 yrs. My truck has made this noise since new. I really don`t know what it is. It really doesn`t bother me. I`m still in warranty but have not brought it to the dealer.   I`m not buying the oil pump prime thing. Screw the TSB. I believe it`s in the trans pump gears. They rattle when that piss poor ULV oil drains off after a while. I believe those sharp tooth gears, with backlash, can rattle when dry. Not a vane style oil pump. Wonder who`s right? Me, or the TSB?🤔   Maybe I`m wrong?

      Wow I'm in a pickle. (Broke down truck) and a story.

      By newdude · Posted

      On the PCM side, blue PCM connector, pin 18, solid gray color (no stripe) wire circuit 435.  That is the EGR low circuit which an issue on that line (be it the wiring, the PCM or the EGR valve or system performance) will trigger P0401 when it tests that code.     There is also a VERY old TSB that states to make sure you clear the DTCs ANY time the PCM is unplugged, reprogrammed, or if the EGR valve is unplugged or replaced as the PCM has an auto zero function in the PCM for the EGR pintle data   61-65-59: SMU - SECTION 6E - ENGINE CONTROLS - CLEAR DTC'S - (Nov 25, 1996)   "CLEAR ANY DTCS FROM THE VCM ANYTIME AFTER DOING VCM REPLACEMENT/ PROGRAMMING, TURNING THE IGNITION ON WHILE THE EGR VALVE IS DISCONNECTED, OR REPLACING THE EGR VALVE."   Some diagnostic aid notes in the GM diag on P0401 for a 1995 S10 Blazer:   Diagnostic Aids Notice: In order to prevent further damage if the EGR valve shows signs of excessive heat, check the exhaust system for blockage (possibly a plugged converter) using the procedure found on the restricted exhaust system check. If the exhaust system is restricted, repair the cause; one of which might be an injector which is open due to one of the following reasons: Stuck Grounded driver circuit Check the oil for possible fuel contamination if a stuck open fuel injector is found. Poor connection or damaged harness - Inspect VCM harness connectors for the following conditions: Backed out terminal BL 18 Improper mating Broken locks Improperly formed or damaged terminal Poor terminal to wire connection Damaged harness Intermittent test - If connections and harness check OK, monitor a digital voltmeter connected between terminal BL 18 and ground while moving related connectors and wiring harness. If the failure is induced, the voltage reading will change.
