## At a glance

- The listed 4.3-inch height gives a low-profile support option for trailer and RV jack feet.
- The feature description says the blocks have a cone base, reinforcing ribs, drain holes, and an ergonomic grip.
- A bag is listed among the included components for storage and carrying.

## Pros

- Four blocks are listed, giving buyers a set rather than a single support block.
- Polypropylene construction and a listed 11.3-inch square footprint make the dimensions and material easy to compare with a jack foot and storage space.
- The manufacturer lists the set for ATV, car, RV, and trailer use.

## Cons

- At a listed height of 4.3 inches, these blocks provide limited lift compared with taller support options.

## Before you buy

- The listing describes these as trailer jack blocks with a 4.3-inch maximum lifting height. Confirm that this height and the block footprint suit your jack and intended support setup. The listed 12,000-pound capacity is a manufacturer claim, not a verified rating for every configuration or surface. The feature text also claims a 10-inch platform and 2.5-inch hole, which are not reconciled with the listed 11.3-inch item dimensions, so verify fit for your jack foot before buying.

## In the box

- 4 trailer jack blocks (Included)
- 1 bag (Included)

## A good fit for

- RV and trailer owners seeking low-profile blocks to support a jack foot.
- Buyers who want four polypropylene blocks and a listed storage bag in one set.

## Less suited to

- Anyone needing substantial wheel-lifting height or a replacement for vehicle-specific lifting equipment.

## Customer feedback

Aggregate ratings skew positive, with most ratings in the five-star category and a smaller share in four- and three-star categories. The sample is limited, and there are no customer-comment details to explain the ratings. For buyers considering these blocks, ratings alone cannot establish how well they fit particular jack feet or perform under specific loads.

## Frequently asked questions

### How tall are the TOWKING TK-TJB-RL4 blocks?
The listing gives a maximum lifting height and minimum height of 4.3 inches. This is a low-profile support height, not a tall wheel-leveling lift.
### What is included in the set?
The listed package contents are four trailer jack blocks and one bag.
### What is the listed load capacity?
The listing states 12000 Pounds. Treat that as a manufacturer claim and confirm that the product suits your particular jack, load, and setup.
### Will these fit any jack foot?
The feature text claims broad jack-foot compatibility, but it also gives a 10-inch platform and 2.5-inch hole while the item dimensions are listed as 11.3 x 11.3 x 4.3 inches. Check the dimensions against your jack foot before purchase.
