ICON Vehicle Dynamics 2021-2024 Ford F-150 4WD suspension systems are designed with maximum performance and the serious driver in mind. ICON's primary focus is to increase wheel travel and damping ability, which translates into outstanding vehicle control and ride quality.

To achieve this, these systems include high-strength CNC machined ductile iron steering knuckles that replicate the suspension geometry of the F-150 Tremor and are effectively a Tremor Inchconversion Inch for your F-150 4WD. This Stage 4 system includes vehicle-specific tuned 2.5 Inch coilover shocks featuring CDCV equipped remote reservoirs for exceptional cooling properties and ICON-engineered coil springs for superior vehicle Inchfeel Inch through the range of travel.

These coilovers are adjustable for 3.5-4.5 Inch of front lift, allowing the use of larger, more aggressive wheel and tire combos. Their combination with the ICON steering knuckles also allows for a 20 Percent increase in wheel travel compared to other ICON F-150 kits.

Billet aluminum Delta Joint PRO upper control arms not only add strength and durability but help retain factory alignment specs, offer on-vehicle caster/camber adjustment, and allow for the extra lift height this system provides. ICON 2.5 Aluminum Series CDCV piggyback reservoir rear shocks utilize vehicle-specific valving and offer increased damping and heat dissipation, balancing the performance of the truck from front to rear.

The included ICON CDC Valves are externally adjustable valves that restrict oil flow into the reservoir which creates 10 levels of compression damping force ranges. ICON Multi-Rate Leaf Springs allow rear spring rate and ride height customization, improve ride quality, and reduce axle wrap by eliminating the factory rear blocks.

Rear ride height is kept within an acceptable range using the ICON billet aluminum 1 inch lowering shackles. The ICON 2021-2024 F-150 4WD Stage 4 suspension system is an excellent choice for those looking to enhance the capabilities of their pickup.

Features and Benefits:
  • This system features upper control arms with ICON's patented Delta Joint PRO. Delta Joint PRO is ICON's innovative new suspension articulation joint which combines the durability and longevity of factory style ball joints with performance and strength that exceeds traditional motorsports-style ball joints. The Delta Joint PRO features a new rebuildable, serviceable design in which any component may be removed, inspected, and replaced without having to purchase a whole new joint. Strength and durability are improved by using a larger ball with 56 Percent more bearing surface than our standard Delta Joint, along with improved lubrication sealing. But improved performance is at the heart of the Delta Joint PRO, with a full 90 degrees of articulation, from one extreme to the other. This represents a 14 Percent improvement in range of motion, over the highly capable original Delta Joint, allowing for maximum bind-free suspension movement through the complete range of travel. The Delta Joint PRO is built to take the abuse, with a chromoly ball and shaft that has a bearing surface hardened to Rockwell C 55. The replaceable races are made of graphite-impregnated sintered metal, machined to the finest tolerance to provide a flawless, metal-to-metal bearing interface. We also redesigned the lubrication system, with lubricant channels that distribute grease more efficiently without extending past the bearing seal.

Adorable, Complete Set—Great for Special Occasions
Color: Beige, Size: 12, Color: Beige, Size: 12
This suit set is such a great find! It comes with everything you need—jacket, pants, shirt, tie, and bow tie—which makes getting a dressed-up look so easy. It's excellent quality for a suit in this price range. The linen fabric gives it a nice, lightweight feel and a polished look that works well for both formal and semi-casual events. My son looked adorable in it, and it was perfect for the spring wedding we attended. What I love: Complete 5-piece set—no need to buy extras Lightweight and comfortable material Classic, stylish look with nice details (lapel, pockets, etc.) Adjustable waistband is super helpful for fit Versatile for weddings, holidays, and other events Fit was true to size based on the chart, but I agree with the recommendation—if your child is between sizes or growing quickly, sizing up is a good idea. I sized up with the hopes that he can wear it again for another event because it looks fantastic! Overall, a really cute and practical suit set that looks great without being uncomfortable. Perfect for any special event

Boys’ 5‑Piece Linen Suit Set
Color: Beige, Size: 16, Color: Beige, Size: 16
I ordered this 5‑piece linen suit in size 16 in the beige color. The set includes the jacket, pants, dress shirt, bow tie, and a slip‑on tie. The outer fabric is a blend of 70% polyester, 25% linen, and 5% spandex, and the lining is 100% polyester. The material is lightweight, which works well for warm‑weather events, but the pants are noticeably thinner than the jacket. The jacket feels sturdier because of the full lining. The jacket has a peak lapel, flap pockets, and cuff buttons, and the stitching and seams are tight and even. I did notice a few loose threads, but the fabric itself was smooth with no tears or flaws. The pants have an adjustable waistband, which is helpful, but the length was too long and will need to be tailored. The overall cut of the suit seems designed for children on the thinner side. The shirt included in my set was a pleated style rather than a plain dress shirt. It wasn’t the style shown in the product photos, and I would have preferred a standard shirt that could be worn for various occasions rather than a very formal shirt. The tie is a pre‑tied slip‑on style with an elastic band. I would have preferred a traditional tie instead. The suit arrived in good condition with no damage, and the color was even throughout all pieces. The price is on the higher end for similar 5‑piece sets. I rated it 4 stars because the jacket is well made and the set includes all the expected pieces, but the thin pants, unexpected pleated shirt, and slip‑on tie kept it from being perfect.

Adorable and Well‑Made Outfit for Special Events
Color: Light Blue, Size: 10, Color: Light Blue, Size: 10
Got this suit set for my son and absolutely love it. It comes with everything he needs to look sharp, and I really appreciate that it includes both a tie and a bow tie so we can switch up the style depending on the occasion. The quality is impressive for the price — the fabric feels light and comfortable, and the whole outfit has a polished look without being stiff or uncomfortable. The fit was spot on, and the adjustable waistband is a huge help for getting it just right. My son looked great in it, and it’s definitely something he can wear for more than one event. The little details on the jacket and pants give it a classic, dressed‑up feel that works for weddings, holidays, or any special moment. Overall, it’s a stylish, practical set that makes getting him ready so much easier. Really happy with this purchase.

Boys linen fabric suit
Color: Light Green, Size: 16
Boys suit set in a lighter green color. This suit is made with good proportions and seems to fit well. The sizing seems slightly big so maybe size down one size. The fabric does wrinkle easily so be aware that sitting and folding the suit may cause wrinkling. Otherwise it is a very nice suit for a formal occasion. It comes in many good colors.

Nice elegant suit for any occasion.
Color: Light Blue, Size: 12, Color: Light Blue, Size: 12
The suit set is very nice, the fabric material is durable and soft. Overall stitching is tight with nice surging of the hems and great construction on the shoulders. Buttons and button wholes are well done. I'm going to iron in the creases on the front of the pants because they weren't folded properly for shipping. The material does hold on to wrinkles so don't be afraid of your iron to get a super sharp look. The color is a soft baby blue that stands out in a crowd of black suits. With the option of an elastic tie or clip on bowtie this is everything you need to make him look presentable for a variety of occasions. My only complaint about this suit kit is the dress shirt is stiff and thin. I found some loose threads that I don't trust to not get played with. I'll probably trade it out for something with a little more cotton. As far as cost goes mid range, but definitely worth the cost. I might consider something with a vest if it's a super formal event, but I'm very happy with how this suit comes together.
