Sure-fit LS Transmission Crossmember for Tri-5 Chassis
Installing an LS transmission into a 1955 to 1957 Chevrolet Tri 5 chassis demands exact alignment, and the Sure-fit Crossmember (Only) Tri 5 meets that need with a simple bolt in design. Crafted from premium steel with reinforced welds, this crossmember maintains factory driveline angles under heavy torque to limit vibration and joint stress. It attaches using original frame holes on non convertible models to preserve ground clearance and ride height without cutting or grinding, and builders will notice consistent shift quality and reduced setup time thanks to precise engineering and direct fitment.
Precision Driveline Geometry for Smooth Operation
This crossmember positions the LS transmission at factory specified angles relative to the frame rails of a 1955 to 1957 Chevrolet Tri 5 chassis. By maintaining universal joints within their ideal operating range, it reduces vibration and coupling stress under heavy torque loads. Preserving original driveline geometry prevents premature wear on bearings and joints, ensuring that shift quality remains consistent from the first gear to the last. The precise orientation also minimizes binding during acceleration and braking, resulting in a quieter cabin experience and a more refined power delivery. Builders will appreciate how this attention to alignment translates to reliable performance over thousands of miles.
Reinforced Steel Construction for Dependable Support
Fabricated from premium grade steel with reinforced welds at key stress concentration points, the crossmember resists bending or cracking under the demands of LS powerplants. Its heavy gauge construction spreads loads evenly across both frame rails, preventing localized fatigue in chassis and transmission mount areas. This robust design guards against distortion during repeated hard launches and long highway runs alike, extending the service life of the brackets and bushings attached. Technicians will find fewer metal fatigue issues and reduced maintenance intervals as a result. Whether on the street, strip, or tour, durability remains constant mile after mile.
Effortless Bolt In Fitment to Save Project Hours
Utilizing existing frame holes on non convertible Tri 5 models, the crossmember installs without any cutting or grinding of the original rails. All essential hardware is included and the clear instructions guide builders step by step through a streamlined process. This eliminates hours of custom bracket fabrication and reduces the risk of misalignment that can occur with trial and error methods. Shops and home garages alike benefit from lower labor requirements and quicker project turnover. The end result is a professional grade installation that gets enthusiasts back on the road faster.
Chassis Integration Without Altering Ride Height
The crossmember profile mirrors the frame rail contour of non convertible 1955 to 1957 Chevrolet chassis, preserving factory ground clearance and ride height. By keeping the transmission tucked within the original rails, it avoids interference with body panels and undercarriage components. This careful fit maintains the classic stance of the Tri 5 while concealing modern drivetrains for a clean vintage appearance. Builders seeking authenticity in both look and performance will value how the design respects original proportions without compromise. The result is a seamless union of midcentury style and contemporary engineering.
This crossmember is engineered to maintain precise driveline alignment and preserve factory ride height for dependable performance mile after mile.
