Sure-fit LS Transmission Crossmember for Tri-5 Chassis
If you're swapping an LS transmission into a 1955 to 1957 Chevy Tri-5 chassis the Sure-fit Crossmember (Only) Tri-5 tackles gearbox support with a precise mount under the factory frame rails. Beyond strength from heavy gauge steel construction this crossmember preserves transmission alignment and resists flex under load. Builders will find the bolt in installation uses existing holes on non convertible frames so they can move quickly from installation to tuning without custom fabrication headaches.
Precision Fit for LS Transmission Alignment
The Sure-fit Crossmember is machined to precise tolerances, establishing accurate relation between the LS transmission and 1955-57 Chevy Tri-5 frame rails. This exact fit minimizes driveline angles, reducing vibration transfer and enhancing throttle response under acceleration. By maintaining true transmission alignment, it also cuts down on premature wear of mounts, bushings and universal joints. Drivers experience crisper shifting and improved vehicle stability as chassis geometry remains consistent even under spirited driving. Over time, this level of precision helps extend service intervals for related drivetrain components.
Heavy Gauge Steel Structure Ensuring Durability
Crafted from thick, premium-grade steel, the crossmember resists bending and fatigue when subjected to the elevated torque output of LS engines. Strategic weld reinforcements at critical stress points ensure the unit absorbs and distributes loads evenly, preventing distortion of frame rails. The robust design guards against metal fatigue during repeated launch and cornering forces, delivering reliable performance over thousands of miles. Its rugged construction gives builders confidence that the chassis will maintain integrity under daily driving or track use.
Tailored Geometry for 1955 to 1957 Tri-5 Chassis
Every contour of this crossmember has been engineered to sit seamlessly beneath the factory rails of 1955-57 Chevrolet non-convertible models. It preserves original ground clearance and ride height by matching frame line profiles, eliminating the need for trimming or adapter plates. The purpose-built geometry accommodates common LS transmissions while keeping driveline angles in check, delivering a classic stance without compromise. This vehicle-specific approach removes any guesswork, so builders can retain the Tri-5's iconic proportions and under-car appearance.
Straightforward Bolt In Installation with Factory Mount Points
Installation relies entirely on existing frame holes, allowing the crossmember to bolt in without cutting, drilling or welding. All necessary hardware and clear instructions are included, guiding users through each step with minimal tools. By bypassing custom bracket fabrication, builders of all skill levels can move quickly from chassis prep to engine tuning. The efficient process reduces shop time and keeps project schedules on track, so you spend more effort dialing in performance rather than wrestling with fitment.
Engineered for precise fit and reliable performance in your LS swap the Sure-fit Crossmember delivers the durability and alignment accuracy needed for hassle free installation and confident driving.
