We had a 53 3100 with a V8 that could PULL anything but couldn't STOP anything. We got a side mount spare tire set up and then poured a concrete spare tire replica to mount in the under bed spare rack. With the weight way at the rear it gave great traction and a good ride and didn't take up any space.

Evan, adding that weight in the rear makes for a great ride but doesn't improve anything regarding stopping does it?

Better traction for the rear wheels DEFINITELY helps the stopping ability, especially since the rear brakes are designed to stop a truck with a full load (or an overload) in the bed.

How's the ride with the concrete spare mounted, like the flint stone mobile?

Until the momentum rolls the weight forward, then all bets are off. Adding more weight means more weight to stop, I'd like to see the empirical data on the addition of weight versus stopping data and find out when this function would reverse itself.

My 52 1 ton has a bed floor of diamond tread plate steel, installed long before my time with the truck.
If it's 1/4" thick that's about 400 lb in a 9' bed. Or 300lb if 3/16" thick.
Hardly takes up any space for being so heavy.

While there is an upper limit of total weight which can be added to a vehicle before momentum exceeds the stopping ability of stock brake design, if the weight is added anywhere behind the rear axle, tire slippage on the pavement will be decreased. Its all about increasing downward force, resulting in increased friction.
That is how the sleds work in tractor pulls. As the sled is pulled down the track, the weights are mechanically moved forward, imparting increased downward force directly over the skid plate, thus increasing friction between the bottom of the sled and the ground.

For our application, it would be best to place the weight as close to the rear bumper as possible. This will allow the least amount of weight needed to gain friction where the tires meet the road. Keeping the amount of weight added to the truck at a minimum will address the issue which sstock has illustrated as a real problem if too much weight is added (if I am reading him correctly).

Spare tire carrier in the rear.

Heavy steel bed floor liner.

Bracket a piece of 4" diameter steel water pipe securely between the frame rails as close to the rear bumper as possible. Drill a few holes in the top. Pour it full of melted lead wheel weights. That will be about 500 Lbs. worth. Instant traction and improved braking ability, as well as a softer ride.

How about filling the pipe with fine lead shot and add a cable operated dump valve so you can lose some weight quick like once the race gets started... I mean for when you need to reduce weight so you can haul heavy freight?
