About the Product
Fits the following: Austin Healey 100 BN2 thru 3000 BJ7
The CapeSport Rear Tramp Bar Kit controls axle movement under acceleration on Austin Healey BN2 to BJ7 models. Engineered to reduce wheel hop and axle tramp, it stabilizes the live rear axle and improves traction without altering ride quality. This revised kit is bolt-on, and replaces the original spring plates with purpose-designed CapeSport plates, so no welding or chassis modification is required.
The kit includes a pair of adjustable tramp bars, replacement shackle plates, and mounting hardware for both sides of the axle. Each component is precision-made from high-grade steel and zinc-coated for corrosion resistance. The design offers the performance benefits of a period competition setup while remaining fully reversible.
Key Benefits
- Prevents axle tramp and wheel hop under acceleration.
- Improves rear traction and cornering stability.
- Maintains correct pinion angle for smooth driveline operation.
- Reduces strain on rear springs and axle mounts.

Installation & Setup
The kit is designed for bolt-on installation using standard workshop tools. Each side replaces the factory spring plate with the CapeSport plate, providing the mounting point for the tramp bar. Once fitted, check that both bars move freely through the suspension range without fouling any components. Torque all fixings to the recommended values and recheck after initial road use.
Professional alignment is advised for cars used in competition or where suspension geometry has been modified.
