The Carli 4.5" Unchained Bypass Suspension System has the most performance out of any bolt-on Ford suspension system you can get! The Unchained is a purpose-built kit. 3.0" 2-Tube Front Kings and 4-Tube Bypass rear 3.0" shocks are paired with fabricated coil buckets, 4.5" lift multi-rate coil springs, and Full Leafs in the rear for unsurpassed off-road capability from a bolt-on suspension system. A roll cage should be considered at this level of suspension.

If you're after a suspension that will allow more off-road performance than the chassis to which it's bolted, this is your huckleberry. With the Unchained Suspension System, we recommend a roll cage and axle truss. This system is far more capable off-road than even the Coilover-Bypass System.

Carli normally specs tubes that are oversized and deep in the travel stroke to allow a high volume of oil to bypass ensuring the shock shaft comes out quickly enough to maintain contact with the ground (doesn't get hung-up in the bump-zone after a large hit). As the shock extends and closes off the rebound tube, all the valving on the rebound side engages to slow the shaft as it reaches maximum extension, top-out. Simply put, the larger the shock diameter, the more capable the setup; the more tubes and "zones", the more adjustability; the larger the tubes, the more fluid can flow around the piston and the more valving you can run to increase the stopping power in the "bump-stop" or "top-out" zone.

The truck will sit 4.5" higher in the front and have more wheel travel thanks to the taller, Progressive Rate Coil Springs that mount into the Fabricated Carli Spring Buckets. Radius Arm Drop Brackets reset the pivot point and keep the travel linear for the best ride while Sway Bar End Links reset the sway bar engagement point. The included Bump Stop Drops protect the shocks from over-compressing while the Adjustable Track Bar centers the front axle and Stainless Brake Lines firm up braking and ensure there is enough line for the newfound travel. To round off the front end, you'll also receive Caster Shims to tighten the steering.

CARLI TUNED KING 3.0" SHOCKS

This system boasts Carli Signature tuned, King 3.0" 2-Tube Front and 4-Tube Rear Piggy-Back Bypass Shocks so large, Carli needed to fabricate custom mounts to fit them; as the old adage goes, there's no replacement for displacement. The 3.0" shock has a piston surface area 45% greater than a 2.5" King and 126% larger than a factory 2.0" shock making it far more efficient in all situations. Additionally, as explained above, they've added bypass tubes to this pinnacle off-road system. The massive surface area and bypass tubes ensure you'll achieve unmatched off-road performance while receiving a civil controlled on-road ride. To fit these shocks, included are fabricated mounts that lift the upper mounting point and position the shock away from the frame while the standard bump stop extensions were shortened to allow for more up-travel to compliment the additional down-travel from the longer shock. In an effort to provide you with the best product, Carli designed a custom piston to determine proper base flow rates to ensure the shock works well in the heavy duty truck platform; the shocks were then tuned based on seat-of-the-pants feel. ALL of Carli's King shocks are rounded off with shafts machined and polished from a solid piece of 17-4 Stainless. Unlike King's standard shafts, there is no coating to wear off, weather is far less likely to hurt them and if there is a small chip, you can round the edges with emery cloth to ensure the seal housing isn't damaged as they're not brittle like the stock, hardened shafts. The shocks are finished with King oil good to -55° F. Note that all King shocks are built with a plated steel body. If subjected to inclement weather for extended periods, we recommend wrapping your shocks in 3M to provide a replaceable moisture barrier.

OPTIONAL FULL PROGRESSIVE REAR LEAF SPRINGS

The rear is outfitted with a Full Progressive Spring Pack requiring no block to achieve proper ride height; thus, travel is extended and wheel hop/axle wrap minimized at the cost of 15% less load capacity than a stock F-250. If capacity is a concern, upgrade with Long Travel Airbags to restore the payload capacity to that of an SRW F-350.

FULL PROGRESSIVE REAR LEAF SPRINGS SPECIFICATIONS:
  • Carli has made the rear leaf springs optional for those already running Carli's Progressive Full Springs
  • Block eliminating, Full Progressive Springs Pack
  • Includes new U-Bolts and Rear Bump Stop Drops
  • Provides a 1/2" rear high stance on 4.5" systems
  • 37" tire fitment
  • Full Replacement Leaf Spring Option Requires NO BLOCKS to achieve level Stance.
OPTIONAL SWAY BAR END LINKS:
  • Corrects Sway Bar Geometry on 4.5" Lift
  • Direct Bolt-In
  • Unhindered Articulation, 100% REbuildable
  • 17-4Stainless Steel Construction

Aesthetically, there will be one huge bypass shock at each corner. The purpose for which the truck's being built should be a huge consideration when purchasing the Unchained. On Road, it's great; Off-Road, extreme caution should be taken as this system is far more capable than the truck. Being bypass equipped, you can expect to hear clicking from the opening and closing of the check valves in the external tubes of the shocks. On the bright side, the suspension is tuned by Carli but fully adjustable to the your preference. You can turn tubes for more float and ride comfort or engage more valving for better control and off-road performance. From Carli, these shocks are setup with a wide open rebound and neutral compression.

CARLI SUSPENSION RECOMMENDATIONS

As with the Coilover Bypass, it's recommended that users purchase a Differential Guard for axle protection, High Mount Steering Stabilizer to keep the steering as controlled as the suspension and Fabricated Radius Arms for strength and Limit Strap mounting. Again, at this level of suspension, a roll cage and axle truss is also recommended if the system will be used to its full off-road potential. On the 4.5" Bypass equipped Ford Systems, we recommend 17"-18" wheels, no more than 9" wide with 4.5"-5" of backspacing with a 37", E-Rated Tire. The more rubber, the better the small bump compliance will be at proper inflation pressures. The ride will firm up as you go larger in wheel diameter.

IMPORTANT NOTES:

NO LEAF SPRING OPTION NOTES:
  • Diesel Power Products and Carli strongly suggest the use of either options available. These options are designed to work flawlessly with the rest of your kit and, are the best way to go. However, we understand you may already have the necessary provisions and/or products to use with this kit so we give you the option to not include any leaf spring provisions.
NO SWAY BAR OPTION NOTES:
  • Diesel Power Products and Carli strongly suggest the use of either options available. These options are designed to work flawlessly with the rest of your kit and, are the best way to go. However, we understand you may already have the necessary provisions and/or products to use with this kit so we give you the option to not include any sway bar drop or Torsion Sway Bar provisions.

OPTIONAL UPGRADES:

LEAF SPRING SHACKLE

Factory rear shackles are strong but can make the ride stiff and bouncy. Carli’s shackles are made from thick steel and have serviceable bushings that let the rear suspension move smoothly, reduce axle wrap and wheel hop. Made from strong 1/4" steel, greasable and rebuildable for long life, provides a far better ride than the factory shackle, and fits both factory and Carli springs

 

LONG TRAVEL AIRBAGS

Long Travel Airbags let you carry heavy loads or tow without losing the smooth ride. They support the rear suspension, reduce sag under weight, and keep the ride comfortable while maintaining proper suspension travel for off-road or daily driving.

 

CARRIER BEARING DROP

The Carrier Bearing Drop lowers the driveshaft carrier to prevent vibration and keep your rear suspension running smoothly on lifted trucks. Carrier Bearing Drop lowers the carrier on 2-piece driveshafts to prevent take-off shudder and driveline vibration, and includes stackable 3/8" shims to accommodate 1"-4" of rear lift.

LOW MOUNT STEERING STABILIZER

  • Minimize steering wheel feedback and maximize control
  • Adjustable nitrogen pressure and custom tuned valves for larger tires
  • Includes differential guard and clamp
  • Optimized for Carli 2.5″ systems

A good read
Format: Kindle
A good read, just fluffy cuteness, no antagonism. I like all the characters. It could have used another round of editing however, glanfds being one error that cracked me up, and my personal pet peeve was that the author kept using the word fill instead of feel, which I promise you are not interchangeable haha, but it's definitely better than the majority of books I read on here mistake-wise.

amazing
Format: Kindle
Knot the Bride was a fantastic read! The characters were all amazing and well-developed. It was easy to like them all. Sophia, Luca, Nick, and Gavin were all perfect for each other. It was such a charming story that had me hooked the entire time. I did wish there were POVs from Luca, Nick, and Gavin but it was still an amazing book without it. I am excited to read the next book in the Willowside Omegaverse series! This is definitely a must-read for fans of omegaverse romance!. I received a free copy of this book and am voluntarily leaving a review.

3 Star Read,
Format: Kindle
This book wasn't bad, but wasn't my cup of tea. It's highly disappointing because the storyline is so original. There is no real conflict or resolution, so the entire thing feels flat. As a lover of omegaverse books, I know there is a ton of variety out there, and ov is really up to the author. But this one is weird. Omegas have multiple scent glands all over their bodies and go into week long heats every month. Alphas have knots in the middle of their shaft instead of the base, and the knot doesn't always swell, no explanation of when or why. It doesn't engage at all when the mouth is in play. I also didn't enjoy the author's writing style. Each paragraph is only 1 or 2 sentences long, and the entire book reads very stacato. The conversations are stiff and unnatural feeling. Everything is very repetitive, both in word choice and in thought. The same thing is repeated 3 or 4 times over a single page, multiple times over. I ended up doing so much skimming. The first 50% of the book is all slow burn, and the last 50% is almost straight mediocre spice. This wouldn't have been all bad if the grammar and spelling errors didn't start at the exact same time. Tongue is repeatedly misspelled in the middle of the spice.

This is the true definition of Cozy Omegaverse. LA wedding coordinator meets her pack at the location for a couple’s destination wedding. Low angst because they are scent matched high heat with heats and knots. Everything you love about this genre with very little anxiety. Simply a fun experience to read and a book I will comeback to when I’m in a slump. I simply love reading this book

Cute Omegaverse story
Format: Kindle
3.75 stars and 2 for spice. Adorable Omegaverse story about a wedding planner who has to go to a small town to plan a wedding for a movie star. While there, she meets her pack. This covers her struggles of not living there but trying to keep her relationship going with her 3 Alphas. It's a quick read and cute, so I recommend it for people who like light-hearted RH stories.
