Rubber vs Aluminum Jack Pads: Which One Should You Buy?

Side by side

Example figures are manufacturer rated, as published on each listing and collected 22 October 2026. Where a listing states a figure two ways, the table follows the title and bullets.

Rubber vs aluminum jack pads: how each side works

The rubber pads compress slightly under load, spreading pressure across the pinch weld. The PLANGER Power PAD Flat is a universal rubber pad for trolley jacks, lifts and axle stands, rated at 3 tons and backed by a 1-year warranty. The TONDA pad is 4.92 inches in diameter and 1.02 inches thick, rated 2 to 3 tons, with a slotted cross-groove that aligns with the pinch weld and a waffle-textured top for grip.

The aluminum pads do not compress: they are machined pucks that hold their shape. Both DEDC pads are aircraft grade billet aluminum with a nylon insert protecting the pinch weld, a 2.7 by 0.47 inch slot opening, 1.38 inch height and a 4-ton capacity. The differences between them are color, magnet count and pack size: the orange pad is a single with 2 installed magnets, the red 2-pack has 1 magnet per pad. The magnets hold the pad on the jack saddle while you position it, which is the aluminum side’s real convenience win.

Capacity

The aluminum pads lead on paper: both DEDC pads list a 4-ton load capacity. The PLANGER rubber pad lists 3 tons and the TONDA 2 to 3 tons. In the listings, the PLANGER names car and SUV, the DEDC pads name car, SUV, truck and van, and the TONDA covers vehicles up to 3 tons; the 4-ton figure matters if you lift heavier trucks. Note the capacities are the listings’ own figures, not independently verified.

Grip and fit

Rubber grips by friction: the TONDA’s waffle texture increases contact friction, and the PLANGER presents a flat face to the weld. Aluminum grips by magnets: the DEDC pads hold themselves in place while you align the jack, freeing both hands. The nylon insert in the DEDC pads is the detail that keeps aluminum from chewing the pinch weld it is meant to protect. All four are made for pinch welds. The TONDA and the DEDC pads are slotted: the TONDA’s cross-groove centers the seam and the DEDC slot measures 2.7 by 0.47 inches. The PLANGER is flat and takes the weld across its face. If your car uses a flat jacking point instead of a pinch weld, the flat PLANGER is the natural choice of the four.

Warranty and listing quirks

The PLANGER is the only one with a stated warranty: 1 year. The TONDA spec table states no warranty. Neither DEDC listing states a term. Two listings contradict themselves: the TONDA bullets give the weight as both 0.11 lb and 245 g, which do not agree, against a spec table 9.92 ounces; and the red DEDC title says red while its bullets say anodized orange, apparently copied from the orange version. In both cases the title wins.

When each material wins

Rubber wins on painted pinch welds and underseal: it deforms just enough to spread the load without biting the coating. That is why both rubber listings emphasize protection from metal-to-metal contact. Aluminum wins on speed and repeatability: the puck goes on the saddle, the magnets hold it, and the lift starts. In a busy home garage doing tire rotations, the magnetic aluminum pads save a fiddly step every time. For a concours car where the welds must stay perfect, rubber’s cushioning is the safer bet.

Frequently Asked Questions

Can one pad serve two cars?

Yes, within reason. All four are universal fit for pinch welds, so one pad can move between vehicles. The 2-pack DEDC exists because lifting usually happens one side at a time, and a second pad means never waiting. Keep a spare in the trunk and roadside tire changes get safer too.

Do I need a jack pad?

If you lift at the pinch weld, yes. The pad spreads the load and stops the saddle from bending the seam or stripping underseal. All four listings here are made for pinch welds. Never lift on the floor pan or a suspension arm with these pads; they are shaped for the vertical seam of the pinch weld, and using them elsewhere defeats the design.

Rubber or aluminum for a daily driver?

Rubber for cushioning: the PLANGER and TONDA pads absorb contact pressure and protect the lifting point from metal-to-metal contact. Aluminum for rigidity and the magnetic positioning the DEDC pads offer.

What do the magnets do?

The DEDC pads have magnets in the slot that hold the pad on the jack saddle while you align the jack under the car. The orange pad has 2 magnets; the red 2-pack has 1 per pad.

What capacity do I need?

Match the pad to the vehicle: the DEDC pads list 4 tons, the PLANGER 3 tons and the TONDA 2 to 3 tons. Any of the four suits cars and SUVs; heavier trucks want the 4-ton figure. Remember the pad is only as strong as the jack under it: a 4-ton pad on a 2-ton jack does not make a 4-ton lift.

Which pads have a warranty?

Only the PLANGER, with a stated 1-year warranty. The other three listings state no warranty term.
