DuroBumps Bump Stops for 4Runner: Front & Rear Picks by Generation

DuroBumps Bump Stops for 4Runner: The Small Parts That End the Big Bang

Every 4Runner has bump stops — little rubber cushions that are supposed to soften the moment your suspension runs out of travel. The factory pieces are an afterthought: hit a ledge, a washboard dip, or a trail obstacle with any speed and the stop compresses to nothing, sending the hit straight through the frame. DuroBumps builds proper replacements for exactly that moment, and they're one of the few suspension parts made for every 4Runner generation — 3rd gen through the 2025+. Here's the whole lineup, who each set is for, and how to pick the right length.

Shop the line: DuroBumps at The Daily 4Runner — fronts and rears from $205.99.

What Bump Stops Actually Do

A bump stop is the last inch of your suspension. When a wheel slams upward — dropping off a ledge, landing a whoop, flexing hard into a rock — the stop is what the axle or control arm lands on. A good stop engages progressively and cushions that hit; a worn or rock-hard factory stop turns it into a bang that shocks, mounts, and passengers all feel. DuroBumps' published numbers tell the story: their stops deflect (compress) a measured amount under a 1,500 lb load — that's the cushioning working before anything metal meets metal.

Front Bump Stops

2003–2024 4Runner (4th & 5th gen): the DBF212 — $214.99. A 5-inch diameter, 2.5-inch tall stop, 2.3 lbs per set, rated for stock height through 3"+ lifts, with .75" of deflection at 1,500 lbs. One front set covers two full generations — the same part serves a 2004 and a 2024.

1996–2002 4Runner (3rd gen): the DBF24R — $205.99. A compact 2.5" × 2.25" stop, just 1.16 lbs per set, .75" of deflection at 1,200 lbs, and no lift required (works with 0–3" lifts).

Rear Bump Stops

2003–2023 4Runner (4th & 5th gen) gets three choices, and the difference is length:

• DBR35 — $229.99. The standard off-road rear: 5×3×3", 1.75 lbs per set, for stock height through 3"+ lifts, .5" deflection at 1,500 lbs. This is the pick for most trucks.
• DBR425 — $249.99. The 2-inch extended version (4.25" tall) for lifted trucks — a 2" lift is required — with .75" of deflection.
• DBR525LT — $269.99. The 3-inch extended long-travel stop (5.25" tall, a full 1" of deflection), built for 12-inch-stroke Dobinsons or Metal Tech rear long-travel kits. A 3" lift is required — this is a serious-build part, not a stock-truck upgrade.

1996–2002 4Runner (3rd gen): the DBR354R — $239.99 (3.5" tall, stock through 3"+ lifts) or the extended DBR525 — $239.99 (5.25" tall, 2" lift required) for lifted 3rd gens.

2025+ 4Runner (6th gen): the DBRTOY2 — $229.99, an OEM-equivalent rear stop (2×2.75×2", .75" deflection at 1,500 lbs, stock through 3"+ lifts), or the DBRTOY3 — $239.99, the +1-inch extended version for 2025+ trucks. (Front stops for the 6th gen aren't in the store yet — the current DuroBumps front covers 2003–2024.)

How to Choose: Standard vs. Extended

The rule is simple: the stop has to reach the axle before the shock runs out of travel. On a stock-height truck, standard length is correct. Lift the truck and the gap grows — an extended stop closes it so the cushion still engages in time. Match the extension to your lift: 2-inch extended for a 2-inch lift, and the long-travel DBR525LT only for genuine long-travel rear setups. Going too long is its own mistake — the stop engages too early and you'll feel it on ordinary bumps.

Install Notes

Bump stops are among the friendliest suspension parts to swap: they're a bolt-on replacement for the factory stops, front and rear, with no cutting or permanent modification. Owners typically do a set in the driveway with basic hand tools and the truck on stands. Do fronts and rears together if you can — a matched set keeps the truck's behavior consistent at both ends when the trail gets rough.

Honest Pros and Cons

Pros

• Real coverage for every generation — including the 3rd gen and the brand-new 6th gen, which most brands ignore.
• Length options that match actual lifts, with deflection specs published for every SKU.
• Bolt-on replacement for the factory stops — no fabrication.
• Individually priced fronts and rears let you stage the upgrade.

Cons

• Fronts and rears are sold separately — a full 5th gen set is $214.99 + $229.99, so budget for both ends.
• Extended stops demand the matching lift; order the wrong length and you've bought a problem, not an upgrade.
• They cushion bottom-outs — they don't fix worn shocks or a lift that needs proper tuning.
• No 6th gen front stop in the lineup yet.

The Bottom Line

Bump stops are the least glamorous suspension part on the truck and one of the most felt. If your 4Runner thumps hard at full compression — or you've lifted it and never touched the stops — start with the standard set for your generation: DBF212 front and DBR35 rear for 4th and 5th gens. They also appear in our 3rd gen accessories roundup and 4th gen accessories roundup — or browse the full DuroBumps collection.

FAQs

Do I need front and rear bump stops, or just one end?
You can replace one end at a time, but a matched set is the better setup — the truck lands at both ends on the trail, and mixing a soft new stop with a tired factory stop leaves the other end still banging.

How do I know if I need extended bump stops?
If your 4Runner is lifted, compare the lift height to the stop: DuroBumps rates the DBR425 for a required 2" lift and the DBR525LT for 3" lifts with long-travel rear kits. Stock height through mild lifts use the standard-length stops.

Will DuroBumps fit a stock 4Runner?
Yes — the DBF212 front, DBR35 rear (2003–2024/2023), DBF24R and DBR354R (1996–2002), and DBRTOY2 (2025+) are all rated for stock height ("No Lift Required" on their product pages).

Is there a DuroBumps option for the 2025+ 6th gen?
For the rear, yes — the DBRTOY2 OEM-equivalent ($229.99) and the +1" extended DBRTOY3 ($239.99). A 6th gen front stop isn't in the store yet; the front lineup currently covers 1996–2024.
