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.

RideTech MOMENTUM Chassis Kits

Ridetech, a leader in air and coil-over suspension systems for more than 30 years, proudly announces the launch of its MOMENTUM chassis kits. This all-new platform gives classic muscle car enthusiasts a clean-slate foundation for their next project—delivering modern handling, increased performance, and design flexibility beyond the limits of factory frames. Builders can now enjoy the benefits of a fully engineered chassis while tailoring the suspension to their preferred style of driving, whether that's comfortable street cruising, high-performance autocross, or full track use. Key engineering highlights include: * RideTech's MOMENTUM Chassis Series is a new platform for classic muscle cars, offering modern handling, optimized suspension, and modular options, initially for 1968-1972 models * Optimized suspension geometry—the chassis re-engineers pickup points to improve camber gain, caster, roll center, and Ackermann steering geometry * Enhanced stability—the chassis is significantly stiffer than a stock frame, which reduces flex and increases structural rigidity for more predictable handling * Improved cornering—a new integrated sway bar helps reduce body roll and improve balance, leading to sharper cornering and greater stability * Confidence-inspiring control—the design provides improved handling for both daily driving and more demanding situations like autocross or track events * Increased tire and wheel clearance—the chassis is engineered to accommodate larger, modern wheel and tire sizes that would not fit on a factory chassis * More aggressive fitment—allows for wider tires (e.g., up to 275mm front and 295mm rear) with room for larger fitments, especially when combined with mini tubs in the rear * Adjustable ride height—the system allows for roughly a 2-inch drop from stock but can be adjusted to the desired ride height * Kit offers modular suspension options that allow for air or coilover setups * Chassis is compatible with existing Ridetech A-body suspension components * Engine and transmission flexibility provides provisions for various motor mount plates (small block Chevy, Olds, Pontiac, Buick, GMLS, or Gen 5 LT) and features an adjustable crossmember that adapts to popular automatic and manual transmissions
