When building a DIY Compact Camping Trailer many folks begin with a Harbor Freight bolt-together style frame kit. The Heavy Duty Harbor Freight frame kit we prefer using has a 2000 lb load capacity. For lightweight home-built camping trailers, this can make for a stiff ride which is why you may need Smooth Riding Camping Trailer Springs.
To remedy this we have developed a Smooth Riding Spring Retrofit Kit.
The Spring Kit has a load capacity of 1150 lbs and rides very smooth compared to the stock setup.
Remove leafs from the pack if you need a lower load capacity for a kayak trailer, bike trailer or motorcycle camping trailer.
For folks building their own welded frames, the springs and many frame building related parts are available from our store.
