Landrum Bump Stop Springs are used in conjunction with primary springs to limit suspension travel during compression. This allows a race car to have a relatively soft initial spring rate and as the suspension nears its maximum compression the bump stop springs, with a higher rate, progressively absorb force. This cushions impacts, prevents the car from bottoming out, and keeps the tires in better contact with the track.
Landrum Bump Stop Springs are made at our Indiana, USA facility and use the same excellent Landrum engineering, materials and manufacturing techniques as our larger coil springs and coil over springs.
With many bump spring lengths and rates available, race teams can find just the right springs to fine-tune their car’s handling.
