Tin Soldier Racecars Low Prep 4-Link Kits

Tin Soldier Racecars Low Prep 4-link kits have taken what they have learned from some of the fastest stock suspension and 4-link small tire cars and combined them into one universal kit. The shorter upper bar allows the car to separate quickly on the launch like a stock suspension car, while keeping the versatility and strength of a traditional 4-link. It's truly the best of both worlds. The chassis brackets are laser cut from 1/4 in. thick plate and feature 1/2 in. staggered holes for all the adjustment you need whether on a radial or slick. The chassis brackets are notched on bottom for 1 5/8 in. tube and have through holes for a 1 5/8 in. tube on top (12 in. spread between). Each bracket has ProJack tabs incorporated into the bottom of the brackets. The axle housing brackets are designed around 275/315 or 28/29 in. tall tires, but still work well with larger tires. They are laser cut from 1/4 in. thick plate and feature 1/2 in. staggered holes for all the adjustment you need whether on a radial or slick. The axle housing brackets are made for 3.5 in. axle tubes and feature 6 in. of shock adjustment in 3/4 in. increments, while including ProJack tabs incorporated into the bottom of the brackets. Steel shock mounts are included. The bars are made from chromoly tube and feature 3/4 in. HD chromoly rod ends with zinc plated jam nuts. The bungs feature a hex adjuster and are constructed from chromoly. Tin Soldier Racecars Low Prep 4-link kits were originally designed for drag radial cars, but after much testing we have found that they really work well on no-prep to moderate prep on any small tire, slick, or radial. If you're looking to increase your traction and lower ETs these kits are for you.

Holley Gen III Hemi Low Pressure Power Steering Pumps

The late-model factory power steering pump on the Mopar Gen III Hemi engines has too much pressure for the steering box on most older muscle cars and trucks, so Holley developed a low pressure power steering pump for Gen III Hemi swaps. These special Saginaw Type II low pressure power steering pumps produce the proper pressure, and the 6-rib billet aluminum pulley is sized to operate the pump at the proper speed when used with the existing drive system on Gen III Hemi engines. The special hardline adapter moves the power steering hose connection to a more accessible location for an easy installation and maintenance. Features and benefits: * Low-pressure power steering pump it—use with factory low-pressure steering boxes on muscle cars and trucks with Gen III Hemi engine * Works with factory "car style" accessory drive system and fits 2003-2008 5.7L and 2005-2010 6.1L Gen III Hemi engines * Also fits some 2009-2013 5.7L and 2011-2013 6.4L with 4.34-inch belt spacing * Prevents damage to steering box on older vehicles * Billet aluminum mount with black anodized finish bolts to existing tapped holes on the left side cylinder head of Gen III Hemi engines * 6-rib billet aluminum pulley with black anodized finish sized for proper pump speed * Power steering pump assembly includes a plastic reservoir * Special hardline moves -6 AN hose connection to a more accessible location

Low Range Off-Road Transfer Case Mounts

All Low Range Off-Road transfer case mounts are engineered to provide perfect alignment, vibration resistance, and superior strength. Their OEM-replacement mounts are tested to ensure they are superior to what other aftermarket suppliers offer. Many competitors' stock replacement mounts are made from inferior materials that make the rubber less pliable and more likely to separate from the steel plates. Serious off-roading, lower-than-stock transfer case gearing, and dual transfer cases can stretch and damage OE rubber, and many aftermarket, mounts. Built for long-lasting performance and durability, LROR's heavy-duty mounts properly securely transfer cases. Construction and materials vary depending on the application, but they typically feature larger mounting surfaces, the highest quality components, and easy installation. Low Range Off-Road transfer case mounts are offered for use with stock and popular dual case crossmembers. Note: Some LROR mounts transfer more vibration during high-speed driving than OEM-replacement mounts.

Low Range Off-Road Budget Lift Kits

Low Range Off-Road budget lift kits are an affordable way to achieve the clearance you need to install larger tires on your 1999-2004 Tracker, Vitara, Grand Vitara, or XL-7. The "Basic Kits" combine Low Range Off-Road's signature red 1.5 in. coil spacers and 1.5 in. front strut spacers to give you a full 2 in. front lift.

The "Complete Kits" include all the "Basic Kit" components with the addition of appropriate length DT3000 Series shocks to get you a great ride and plenty of flex. You can use your factory rear shocks, but they will limit your travel. Select the Low Range Off-Road budget lift kit designed for your vehicle year, make, and model. Note: While these lift kits are designed to provide significant aesthetic and performance improvements, it is important to understand their limitations compared to more expensive, comprehensive suspension lift kits.
