Description

If JKS designed the factory JL Wrangler suspension, this is how it would be done! Introducing the JKS 1.5" J-Spec Suspension System with your choise of specially tuned FOX 2.0 IFP Adventure Series, FOX 2.0 IFP Performance Series, FOX 2.5 IFP Peformance Series, or FOX 2.5 Performance Elite Series shocks. Whether your focus is improving on-road characteristics or suspension performance in the backcountry, this system has been carefully engineered to excel in a variety of terrain while providing clearance for up to 35" tires. The JKS dual rate coil springs are a tried and true design that provides excellent versatility - on-road comfort is provided by the softer rate, while the firmer rate increases capacity for your gear and improved control off-road. All springs are scragged to eliminate settling after install and shot-peened to add more surface area, significantly increasing long term durability. The springs have a longer free length, creating a low-lift height system with excellent wheel travel when you need it during off-road expeditions. The FOX 2.5 IFP Performance Series shocks have been tuned side-by-side these dual rate springs to create a complete fine-tuned package. Tuned specifically for optimum ride and performance on plus-sized wheel and tire packages, these shocks feature the same high-quality aluminum bodies and internal floating piston architecture used in FOX Performance Series 2.0 shocks, now in a new 2.5-inch diameter body. The larger diameter valve shims translate to a smoother feel - think firmness without harshness, allowing for a softer tune. 50% more piston surface area provides less damping fade and more bottom-out control at higher speeds, increasing on and off-road control. Paired with JKS dual rate springs, this shock and spring combo creates control and comfort even with moderate increases in weight, giving you the freedom to loadout your vehicle with the gear you need. Additional weight may affect net ride height - for very heavy vehic

Go to LEER Truck Accessories by H&H for your truck needs. Luis and Justin were perfect, I purchased my own running boards to get installed on my truck. Let’s just say the prices were VERY REASONABLE!!!!!!!!! My appointment was at 2:00pm and out with my truck at 2:45pm. Job well done guys. We just moved to the area and I was looking for a truck accessories company. You cannot go wrong with LEER Truck Accessories by H&H. So if you are in the area of Marietta off of Cobb Parkway stop by and check those guys out. I will definitely be back for more upgrades for sure. Thanks you have a customer for life!!!!!

Stopped in to inquire about a new truck bed cover for my husband’s brand new 2500. Staff was very helpful and gave us options of what he was looking for. Surprisingly the cover my husband wanted was in stock. We were in and out in 30 mins with a new installed truck bed cover. Amazing service.

I was desperate, I couldn’t open my truck topper door. I stopped there to see if they could help. WOW did they ever! Very great service, friendly & mechanically qualified to help. Had the door open & repaired in less than 15 minutes. I tried to pay & they said; “no charge”. I’m definitely going back there! Mike H

Just had Arcane Warrior roof rack installed. Unbelievably quick and convenient service. Blake and Garrett were readily available and exceptionally personable. Highly recommend them for any and all truck accessory recommendations, provisions and installations!
