Description

Carli 4.5" Unchained 3.0 Bypass Suspension System 08-10 Ford 6.4L PowerstrokeThe 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 looking for the best on road ride offered by Carli with a huge boost in off road capability, grab a Dominator.

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 looking for the best on road ride offered by Carli with a huge boost in off-road capability, grab a Dominator. 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, Carli recommends a roll cage and axle truss. This system is far more capable off-road than even the Coilover-Bypass System.

CARLI UNCHAINED SUSPENSION SYSTEM COMPONENTS

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.

SWAY BAR END LINK SPECIFICATIONS:
  • Corrects sway bar geometry on 4.5" lift
  • Direct bolt-in
  • Unhindered articulation, 100 percent rebuildable
  • FK bearing 5/8" rod ends

REAR LEAF SPRING KIT

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 a SRW F-350.

FULL PROGRESSIVE LEAF SPRING KIT SPECIFICATIONS:
  • Block eliminating
  • Light 3/4 ton capacity, full capacity attainable with long travel airbags
  • Includes new u-bolts and rear bump stop drops
  • Provides a 1" rear high stance on matching 4.5" suspension systems
  • 3.5" axle tube

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, Carli recommends wrapping your shocks in 3M to provide a moisture barrier that's replaceable.

WHEEL AND TIRE FITMENT

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, Carli recommends 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:
  • WHEELS: Carli Recommends a 17"-18" Wheel, no more than 9" wide with 5" of Backspacing on 4.5" Lift Systems.
  • TIRES: 37", E-Rated Tire Fitment is Recommended. Recommended unloaded Tire Pressure 45F/40R
  • RECOMMENDED CONFIGURATION: Carli 4.5" Systems are Designed and Tested on Vehicles with 17"-18" Wheels with 37", E-Rated Tires. Stock wheels and tires or running a larger wheel diameter will result in a stiffer ride.
  • REAR DRIVESHAFT Trucks equipped with a 2 piece driveshaft will require CS-CARRIERDROP-F to ensure proper driveline angles.

  • 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.

Two Filters, Quick and Easy
Size: 16-23 Tacoma, Size: 16-23 Tacoma
The RVgolf Engine+Cabin Air Filters Kit for the Toyota Tacoma V6 comes with two air filters. There is a cabin air filter that fits nicely into the compartment accessed through the glove box and an engine air filter that dropped in easily in the compartment under the hood. Replacement of both filters was easy, didn’t require any tools, and it took more time to empty and replace the items in the glove box than it did to replace both filters. The Toyota dealership quoted me $80 to replace the cabin air filter only. I replaced both filters for less than $30. The filters felt like they were good quality. The engine air filter is multi-layered, with a thin foam layer to keep larger debris from blocking the finer paper filter. The cabin air filter said and looked like it had a carbon layer to absorb smells. The only concern I had was size. After I had replaced both filters I went to slide the engine air filter I replaced into the RVgolf box to throw it away. The engine air filter I replaced would not slide into the RVgolf box. It was too big. After driving for a few days and a couple of hundred miles, I popped the hood and checked the fit of the engine air filter. The fit looked perfect. See attached photos.

Fits 2019 accord (gas engine)
Size: 18-22 Accord
Dealer was going to charge almost $200 to change both of these filters in my 2019 accord. These filters fit perfectly and of same quality as the dealer product. Easy to install, saving me lots of money.

Great quality and Easy to install
Size: 18-22 Accord
As someone with zero experience changing air filters, I was honestly surprised at how easy this was. The fit was perfect for my 2010 Honda Accord Sport, and both the cabin and engine air filters installed with no issues at all. It even came with clear, easy-to-follow instructions that made the whole process stress-free. Saved myself money from going to the dealership, and my car is running great. Definitely recommend for beginners wanting to do a simple DIY maintenance job.
