Hellwig Frame FX Kits

One of the most effective ways to improve the stiffness and handling of your vehicle is to box the factory chassis. Hellwig Frame FX kits makes it easy for you. Rather than taking considerable time with measuring, cutting, and fitting steel panels these kits simplify the process effectively. Some vehicles have an open C-channel chassis that's only 3 in. wide at the top and bottom. This design is inherently weak in handling torsion and marginal in bending. Frame FX kits double the width of the tension side of the frame rail and close the area for dramatic increases in torsional and bending stiffness. They're comprised of 14 pre-cut 10-gauge steel panels matching the thickness of the factory frame--and fit into the weak points of the factory chassis. Hellwig engineered another panel that adds an extra mount to tie the floor to the chassis, furnishing even more strength to the entire car. In addition, brackets are provided to mount the transmission crossmember, with enough adjustment to accommodate nearly any drivetrain configuration. The increased strength via Hellwig Frame FX kits results in improved handling and ride quality, while retaining the factory chassis and mounting points.

All-Pro Off-Road Expedition 2.0 Rear Leaf Springs

All-Pro Expedition 2.0 rear leaf springs are developed as an all-around off-road suspension option with long-term expedition capabilities.

So, the expedition products are a natural addition to its product line. A higher leaf count spring allows the use of thinner leaf material that yields a more flexible and progressive leaf stack, or pyramid, producing a much smoother spring rate curve throughout the complete suspension cycle. Expedition leaf springs are designed to carry up to 1,000 lbs. consistently. Expedition 2.0 leaf spring specifications: * Number of leaves 9+1 Overload/Rebound * Eyelet-to-eyelet length (free): 54 3/8 in. (1381mm) * Spring rate: 248 lbs./in.

All-Pro Off-Road Expedition Rear Leaf Springs

All-Pro Off-Road now offers a heavy-duty Expedition version of its popular rear leaf springs for Toyota Tacomas. Long known for the superior quality and off-road performance of their standard-duty leaf springs, All-Pro's new Expedition leafs are specifically designed to combine off-road performance with heavy-duty weight carrying capacity. The popular expedition-style trend in off-road vehicles is resulting in trucks that are carrying heavier loads than normally seen off-road. Specialized long-distance excursion gear such as roof-top tents, recovery and repair gear, camping equipment, and extra water and fluids can add significantly to the cargo weight of expedition vehicles, exceeding the intended operating parameters of typical performance leaf springs. All-Pro's Expedition leaf springs feature a 20 percent higher spring rate than their standard leaf springs. They are otherwise identical in dimension and quality, providing the same eye-to-eye measurements and wheel travel. These Expedition leaf springs are designed to carry up to 500 lbs. consistently.

All-Pro Off-Road Long-Travel Leaf Springs

Looking for super trail flex combined with a stable street ride ... and a great price to boot? Then All-Pro Off-Road has your springs—featuring all the benefits of a custom spring with the advantages of mass production (lower cost and quicker delivery). All-Pro front long travel leaf springs are made to strict specifications, ideal for rock crawling, soft enough to allow flex on the trail, yet stiff enough to drive on the freeway safely. Factory springs and other aftermarket springs are made with different packs, left and right, to accommodate the mismatched factory perches. Using two different springs works as long as the springs are designed for the exact weight of the truck. However, if the weight of the truck differs from the ideal weight for the springs, the truck will lean to one side or the other because these springs have different spring rates. Designed for 1979-95 Toyota pickups and 4Runners in the 3,000 to 4,500 lb. range, all of the All-Pro front springs are identical, left and right. Included with each set is a small pad to be welded to the driver side spring perch, making both perches the same height. Identical left and right springs won't cause your truck to lean the way other aftermarket springs can. Order the pair recommended for your application.
